How to start poplar trees from cuttings


Can You Plant a Poplar Branch & Will It Regrow? | Home Guides

By Rachel Lovejoy Updated May 11, 2022

Poplars (Populus spp.) are fast-growing trees that can be successfully grown from stem cuttings. Lombardy poplar (Populus nigra) and hybrid poplar (Populus deltoides x nigra) are hardy in U.S. Department of Agriculture plant hardiness zones 3 to 9, says Arbor Day Foundation, while the tulip poplar (Liriodendron tulipifera) is hardy in USDA zones 4 to 9.

Vegetative Propagation

In poplars, as well as many other species of woody plants and trees, rooting hormones are stored in the vicinity of buds or undeveloped leaf nodules. When exposed to heat and moisture, roots develop at these sites to produce new plants. The practice of producing new trees and shrubs from stem cuttings is called vegetative propagation.

Whereas growing plants from seeds doesn't always produce the desired result due to the hybridization of different varieties, growing a poplar tree from a stem cutting assures that you will get the exact same type of tree, or clone, as the parent tree. Whether you are growing one poplar tree or many, using your own poplar cuttings saves money and produces quick results in a very short time.

Types of Cuttings

According to North Carolina State University, "The four main types of stem cuttings are herbaceous, softwood, semi-hardwood and hardwood." The categories refer to the growth stage of the parent, or stock, plant, and is important to consider when deciding when to take cuttings. Their classification as woody plants means that poplars can be propagated by means of softwood or hardwood cuttings, each of which is done at different times of the year.

Softwood cuttings use the new growth on a poplar tree just before it matures or hardens. Shoots growing at the base of the tree or elsewhere along its roots can also be used and generally appear between May and July. Hardwood cuttings are done in late fall to early spring and are taken from dormant mature stems.

Making the Cuts

Poplar cuttings do best if taken from healthy trees, especially if taken in the early morning. Use a sharp, thin-bladed knife or sharpened pruning shears and remove all the leaves from the bottom half of a 6-inch stem. If the leaves on your cutting are large, cut them in half to reduce water loss during rooting. Place the cutting up to half its length in a medium made of half peat and half sand; water well and keep in a spot that receives indirect sunlight. Keep the soil moist but not saturated by occasionally misting the cutting.

When it has rooted, transfer it into a larger container or into a separate bed with others as its chances of survival are improved if not immediately planted in its permanent location. Cuttings, also called whips, can be harvested in late fall and refrigerated until planting time. If using this method, be sure to soak the cutting for 24 hours before planting and keep the area weed-free during the first two years of growth as young poplars are easily overtaken by other vegetation.

Considerations

One of the reasons that poplars grow so rapidly is that their roots aggressively seek out water and nutrients, which can be problematic in a small yard or close to a septic system. New trees often sprout at points along the extensive root system and should be mowed or dug up by hand. The rule of thumb is to plant poplars at least 100 feet from a building or drainage field, and be sure to eliminate any sprouts that may pop up within that space. New plants can be discarded, given away or planted in another location as long as you adhere to the 100-foot minimum rule.

How to Grow Poplar Tree

Tall and elegant, the poplar tree is an ideal way to bring structure, focus and shade into your garden. An attractive deciduous plant, the poplar tree is a great choice if you want to introduce privacy or shelter to an outdoor space.

Thriving in warm weather and moist soil, most varieties are hardy in USDA Zones 3 to 9.

Most poplar tree varieties are easily identified by their foliage. This is often heart shaped, and if you look closely, edged with small teeth. Green in the autumn, the foliage turns a golden or yellow shade, depending on the variety, in the fall. Interestingly the poplar tree sets both male and female flowers, meaning that it can self pollinate. This leads to the plant producing yellow flowers and small fruit.

The poplar has long been used to add height and structure to an outdoor space. As well as a great way to introduce natural privacy, they can also be used to line paths and driveways.  

With over 35 different species, as well as numerous hybrids, to choose from, you are sure to find a plant that suits your situation. Here is your complete guide to growing a poplar tree.

Different Poplar Tree Varieties


Fast growing but not long lasting, these plants have a lifespan of around 50 years. Selecting the right variety for your garden and caring for it correctly can help to extend this lifespan for as long as possible.

While there are over 35 recognised species, very few are commonly grown in domestic settings.

The most commonly grown are

  • White (Populus Alba), this cultivar is native to Southern and central Europe and South Asia. With a distinctive pale grey bark, the leaves of this plant can reach up to 20 cm in size. Its colorful flowers, or catkins, turn red if they are male and yellow green if they are female. Following fertilization the plant produces masses of cotton like seeds. This cultivar can reach a height of 65 to 100ft, depending on growing conditions.
  • Eastern or Cottonwood (Populus Deltoides). Reaching a height of around 80 ft, and a spread of 60 ft, this is another large specimen. Pleasingly drought tolerant, its dark green leaves turn a pleasing shade of yellow in the fall. The bark of mature plants turns ash-gray in color.
  • Lombardy (Populus Nigra Italica) is a reliable and popular cultivar. A fast growing plant, growing roughly 6 ft a year, Lombardy is a good choice if you want to create a wind break or a privacy screen. Helping to create the iconic column shape of the poplar tree, Lombardy has an unusual branching structure. The branches start close to the ground and grow upwards, in parallel to the trunk. While the foliage does yellow in the fall, the plant is not, unlike other cultivars, grown for its autumn foliage. Another distinctive feature of the Lombardy is the trunk which blackens as it ages.
  • Balsam (Populus Balsamifera) reaches heights of up to 100 ft. Balsam grows in an attractive, cylindrical shape. This is also a fragrant cultivar. During the spring, as the buds open the resin which coats them emits a distinctive, almost exotic smell. The Balsam cultivar is commonly found in damp or swamp-like conditions.


The distinctive pale foliage of the Populus Alba. Take the time to find a variety that best suits your growing conditions and situation. 

Source your saplings from a specialist supplier or plant nursery. They will be able to help you select the ideal variety for your situation.

Be careful when selecting your sapling. Some nurseries sell male only plants. This means that the plant won’t produce masses of cotton like seeds which can be scattered on the wind. However male plants produce lots of pollen, which can be a problem if, like me, you suffer from hayfever.

Saplings are usually sold as 10 inch plants. If your garden is prone to foraging deer and other pests, select larger saplings, about 18 inches tall. The larger the sapling, the quicker it grows.

Where to Position Your Poplar Tree

If planted in the right location, care is pleasingly simple.

The poplar tree does best in a fertile soil. Use a soil test kit to assess the condition of your soil. The soil should be either acidic or neutral, a pH reading of between 5 to 7.5 is ideal. These plants struggle in extremely acidic soils.

Your chosen location should be a full sun position. Low lying moist ground is perfect. While they prefer well draining soil, these plants can also cope well with wet and boggy conditions.

Remember, when selecting your location to consider the final size of the plant. The poplar tree can be 50 to 165 ft in height. It’s trunk can achieve a diameter of 8 ft. To maintain this spread and size the plant must grow a large and extensive root system.

This root system can easily disrupt foundations, paths, pipes and sewers. Make sure that your chosen site has enough empty space for the plant and its root system to grow into. If you are unsure what is beneath your soil, contact your local utility or water company. They can mark out exactly where any pipes and sewers are, helping you to avoid any costly planting mistakes.

To minimise root spread dig a planting trench and line the sides with a durable, heavy duty material such as Deeproot Bamboo Barrier.

These plants do best in light, sunny positions. If you are planting more than one, be sure to space them out correctly. 

If you are planting a windbreak, aim to plant the saplings at least 50 ft, but no more than 200 ft, away from the area you want to shade.

How to Plant

Before planting, prepare the ground by digging over the soil and weeding well.

The poplar tree should be planted during its dormant season. This lasts from November until mid-May. Try to plant as early in the dormant season as you possibly can. This gives the saping time to settle and establish itself before the first frosts hit. Alternatively, wait until the last frost date has passed before planting. Whenever you plant, the soil temperature should be above 50 ℉.

Dig a hole deep enough to hold the saplings root ball. Ideally, the finished hole will be twice as wide as the root ball. Use a shovel to roughen up or loosen the sides of the hole. This helps the roots to spread more easily. When placed in the hole, the sapling should sit at roughly the same depth as when it was in the pot.

Position the sapling in the center of the hole. Carefully backfill the hole, being careful not to disturb the plant too much. You may need someone to hold the sapling in place as you do this.

After planting mulch around the base of the plant. This helps to suppress potentially damaging weed growth.

Planting is the ideal time to install a stake or support such as the Kradl Tree Staking Kit. This is an easy to use kit that is both robust and reusable.

You may also need to cover the trunk of the spaling with a guard or mesh to protect it from rabbits or other destructive pests. Tree Guard’s Plastic Mesh Bark Protector is easy to install and protects against both rabbits and deers.

If you are planting more than one poplar tree, space them at least 3 ft apart. The exact distance varies depending on the variety that you are growing. For example Lombardy’s require spacing of at least 8 ft.

Caring for a Poplar Tree

Weed regularly around the base of the plant. Weeds sap the soil of moisture, causing plants to struggle, particularly during warm weather. After weeding, laying a 2 to 3 inch thick layer of mulch helps to suppress weed growth.

When to Water

Water newly planted saplings regularly until they are established. This can take several weeks.

Once established water requirements are minimal. These plants require about 1 inch of water every two weeks. You may only need to water during particularly dry or warm periods.

Fertilizing Your Plants

A poplar tree in good or rich soil is unlikely to require fertilizing every year. If you apply an organic mulch to the soil around your plant it will gradually break down through the year, adding nutrients to the soil.

If the distinctive heart shaped foliage is not as large or as green as it should be, you may need to fertilize the plant.

If the stem adds less than 6 inches of new growth in the spring, or if the foliage seems small and pale, you may need to fertilize the plant. This is best done in the fall.

To fertilize, work a multi purpose granular fertilizer onto the soil, under the poplar tree canopy. Cover as much of the area under the branches, also known as the drop line, as possible. Don’t allow the fertilizer to contact the trunk.

Alternatively, you can apply a water soluble or liquid fertilizer.

Do not fertilize during the first season.

The amount of fertilizer you need to apply varies depending on the size of the plant and the product you are using. Consult the information on the fertilizer packet before applying.

Pruning Your Plant

The poplar tree is a surprisingly low maintenance plant. Most cultivars develop and maintain their own structure. However Lombardy cultivars are known for dropping leaves and twigs which will need to be cleaned away.

Regularly inspect your plant for signs of disease or broken limbs. Use a sharp pole saw to remove diseased and damaged sections as soon as you notice them. This helps to keep the plant healthy and prevents serious issues such as canker from developing.

How to Propagate a Poplar Tree

While the poplar tree does produce seeds, propagation via cuttings is a lot easier.

Take hardwood cuttings in late spring. The cutting should be about 6 inches long, and taken from a healthy stem about a quarter inch in diameter. Use a sharp pair of garden scissors to take a cutting just below a pair of leaves.

Remove leaves from the lower three quarters of the cutting, leaving about 4 or 5 leaves on the top half.

Pot the cutting in a 6 inch pot filled with well draining, fresh potting soil. You can also plant the cuttings in an even mixture of coarse sand and perlite. Firm your chosen potting mixture down and water well.

Place the pot in a shaded, sheltered position, either indoors or outdoors. Mist it regularly, keeping the leaves moist. Water the soil only when it feels dry.

Roots should form within two weeks. To check that roots are present, gently tug the cutting. If you feel resistance it is a sign that roots are forming.

Once roots have formed, transplant the cutting into a 6 inch pot and continue to grow on in a shaded position for up to 3 months. The cutting can be transplanted into its permanent location in the fall, in milder climates, or in the early spring in cooler USDA Zones.

Common Poplar Tree Problems

Borers, bacterial wet wood and canker can all affect the poplar tree. Many varieties will develop stem canker at some point. If allowed to go untreated, this issue can cut the plant’s lifespan significantly.

Canker can cause physical deformities and can be a sign of a serious disease. Initially canker causes dark or sunken areas to form on a branch or trunk. This gradually spreads across the plant. If allowed to cover over half of the plant’s circumference the plant will be almost impossible to save.

Different varieties of poplar tree are prone to different strains of canker. For example the Silver Leaf, Lombardy, Carolina and Simon cultivars are more likely to develop Cytospora chrysosperma or Leucocytospora nivea than other forms of canker.  Lombardy cultivars can also develop Crytodiaporthe populea. Most other poplar tree species are resistant to this issue. White cultivars tend to develop Hypoxylon mammatum. European aspens and pussy willows are also prone to this canker strain.


Regularly inspect your plant for signs of damage or disease. Noticing problems early is vital if you want to keep your plants as healthy as possible. 

While canker can’t be cured, you can stop it from spreading. Weak or sickly trees are more likely to develop this as well as other health issues.

To keep your plant healthy, water only during dry periods and fertilize sparingly. Also take care when pruning and tidying up your plants. Canker is caused by fungi entering the plant through open wounds.

Regularly inspect your plant for signs of disease and canker. Prune away broken or diseased branches as soon as you notice them. Also remember to sterilize your tools before and after use.This helps to prevent the disease from spreading.

If a plant is severely affected, dig it up and destroy it before the disease can spread to other plants. Do not place the plant on the compost heap.


Attractive and easy to care for, these plants bring structure and color to a garden throughout the year.  

Elegant and attractive, the poplar tree is a great way to add structure and definition to a garden. A useful way to introduce shelter or privacy to a space, once planted the poplar tree is also pleasingly easy to care for. By following the advice laid out in this guide you will be able to enjoy the cool shade of the poplar tree for years to come.

Propagation method of white pyramidal poplar (male form) in the culture of isolated plant tissues for landscaping settlements in the Irkutsk region

Method of propagation of white pyramidal poplar (male form) in the culture of isolated plant tissues for landscaping settlements in the Irkutsk region

Poplar is the most suitable tree species for landscaping settlements, as it grows rapidly, forms a large leaf mass, effectively protecting the air from dust and harmful gases. One of the disadvantages of poplar is the formation of fluffy seeds in female plants, which sometimes forces us to abandon its use for landscaping. Among a large number of poplar species, white poplar is of particular interest for landscaping ( Populus alba L.), which has highly decorative foliage, due to which it is called silver poplar. In addition, it is resistant to leaf rust, due to which the most common balsam poplar in the cities of the Irkutsk region sheds its leaves early and ceases to perform a protective function already in August-September.

In the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (Novosibirsk), a form named "In Memory of Vavilov" was selected. These are male, non-fluffy, with a narrow pyramidal crown, with leaves that have a dark green surface and a white-felt underside. This gives such trees a high decorative effect. In addition, the foliage lasts a long time in the autumn, as it is resistant to rust. This form is recommended for landscaping Irkutsk (Sizykh et al., 2012). An example of the successful use of white poplar "In Memory of Vavilov" for landscaping is its planting along the perimeter of the "Eye Microsurgery" complex in Irkutsk (Figure 1).

Figure 1. White pyramidal poplar (form "In memory of Vavilov") growing on the territory of the Eye Microsurgery complex in Irkutsk.

An obstacle to the widespread use of this form of poplar is the difficulty of its reproduction, since green and lignified cuttings taken from the crown of an adult white poplar tree practically do not take root (Bakulin, 2012), which was also observed in our experiments.

To overcome the weak rooting of this poplar, a biotechnological method was used - clonal micropropagation. Awakened buds on a branch taken from one of the trees growing on the territory of Eye Microsurgery were introduced into an isolated culture and have been constantly multiplying in test tubes since 2011 (Fig. 2). When they are planted in containers with soil, they form seedlings (Fig. 3). This seedling is used to grow seedlings, which are then planted in a permanent place (Fig. 4).

Figure 2. Clonal micropropagation of white poplar. It can be seen that microplants easily form roots.

Figure 3. White poplar seedling obtained from test-tube plants.

Figure 4. White poplar trees growing for the third year on the territory of the Institute. The height of the person in the picture is 155 cm.

In 2014, about 150 plants were obtained, which are grown on the territory of the institute to obtain seedlings.

Propagation of poplar. Poplar: cultivation and care

All poplars have two great advantages - fast growth and unpretentiousness. Poplars are often used as a "pioneer" crop to develop new areas, as well as to protect the garden by forming windbreaks.

Never plant poplars near the house, gazebo or paths - a strong root system can cause you a lot of trouble in the future!

  • Height: 12 to 30 m
  • Width: 3 to 10 m
  • Foliage classification: deciduous tree
  • Frost resistance: high
  • Soil: ordinary garden, cool
  • Growing method: as tapeworm, in row planting, in ornamental group
  • Pruning period: autumn-spring, from October to April

Planting

The planting pit must have at least a cubic meter in volume. Cultivate the soil inside the pit and on its walls - the presence of loose earth favorably affects the growth of the seedling. Place a peg support in the hole, then a seedling, fill it with soil, tamp it down, form a watering place (sides) and spill it abundantly. Don't forget to tie the stem to the support.

Pruning

Shaping pruning

After planting, keep only one apical leader growing vertically upwards - it is thanks to him that the plant will stretch in height. The main criterion is that the crown should have an even shape, the shoots should not stick out of it. No pruning is required for columnar forms.

Sanitary pruning

Poplar tolerates pruning well. So you can not be shy and, for the purpose of rejuvenation, feel free to cut off an adult plant (30-40 years old) - at least 15-20% of the height.

Propagation

Propagation by cuttings

Everything is very simple here. In February-March, prepare cuttings 25 cm long, it is necessary that the buds on these shoots are well formed. Place the cuttings in a damp mixture of sand and peat.

Care and agricultural technology

Poplar is a big fan of moisture. In the first year of planting, water two to three times a month, as well as during the dry season. Trunk circles to preserve moisture in the soil are loosened after each watering. It is desirable to mulch with humus, peat or sawdust immediately after planting and watering. As already mentioned, poplars lend themselves well to shearing and pruning and easily restore the crown. Immediately after any trimming, all wounds with a diameter of more than 2.5 cm should be covered with garden putty or painted over with oil paint on natural drying oil. Shield prophylaxis is required.

Everyone knows beautiful tall trees - poplars. They are in almost all yards, some plant them in their summer cottage or near a private house. In our article, we will tell you what a pyramidal poplar is and give a description of it.

Pyramidal poplar belongs to the Willow family. In height, it can reach 40 meters, and in width - up to 1 meter. It has a pyramidal crown: the branches rush upwards. Flowering falls on March-April. One poplar can live for over 300 years. The tree has a smooth gray bark, a well-developed root system. Growth is pretty fast.

The willow family also includes willow and its species: weeping, goat, dwarf, spherical, whole-leaved.

Important! Despite the fact that poplar belongs to light-loving plants, it is better to provide it with shade in the first year of life. This can be done artificially - by creating a canopy or shelter. Grows best on loamy, slightly acidic and neutral soil, loves moisture, light and tolerates frost well. Often found on roadsides.

How to choose seedlings when buying

If you decide to buy seedlings, we do not recommend going to the market. To find a really healthy tree, it is better to contact a specialized store or a farm that is purposefully engaged in growing seedlings.
Pay attention to the fact that the young tree should have a light bark, several shoots. Look at the root system - if it is not visible due to the large amount of land - it is better not to buy such a plant. It is better to purchase male seedlings - they do not produce fluff, which adversely affects people's health, causing allergies.

Selection of landing site

When choosing a place to plant, be sure to consider that the tree will grow and have a powerful root system that can damage the foundation, destroy the asphalt. That is why it is not recommended to plant poplars closer than 50 meters from buildings, and also too close to the roadway.
Pyramidal poplar loves open sunny areas - this must also be taken into account when choosing a landing site.

Step by step seating process

In order for a tree to take root, certain rules and recommendations must be followed. It is best to plant in autumn or spring - it is at this time that the trees take root best. It is necessary to plant cuttings, on which there must be several live buds.

We invite you to familiarize yourself with the step-by-step instructions for planting poplar:

  1. It is necessary to dig a hole 1 meter deep.
  2. Give the seedling good drainage.
  3. Deepen the seedling into the hole. In this case, the root neck should not be deeper than 2 cm.
  4. Sprinkle the seedling with earth.
  5. For more stability, tie a young tree to a support until it is strong.

When creating a row of pyramidal poplars, trees should be planted at a distance of 1.5x3 meters or 2.4x4 meters.

Care of young trees

Planting and caring for pyramidal poplar require some effort. Young trees are recommended to be watered twice a month. Since the tree has a developed root system, it is necessary to pour at least 25 liters of water under each seedling. Periodically, it is recommended to loosen the soil around the trunk - this will contribute to the rapid growth of the tree.
In autumn and spring, it is necessary to bayonet to a depth of 10-15 cm.

Care of mature trees

After 6-7 years loosening of the soil can be omitted. Watering is done extremely rarely, once a month is enough, and with regular rainfall, you can not water the tree at all. After this time, the trunk circles are usually sown with lawn grass. From time to time it is necessary to carry out pruning to form a crown. After this procedure, all sections with a diameter of more than 2.5 cm are covered with garden putty.

Pruning should be done every year from a young age. It is worth cutting half the length of the shoots, leaving 10-20 cm on the poplar. Shoots should not stick out of the crown, it should be even. Since the rate of growth of the pyramidal poplar is quite high, pruning may be required more frequently.

Do you know? Poplar is the only tree that continuously saturates the atmosphere with oxygen. The rest of the trees are able to produce oxygen only during daylight hours.
If you want to rejuvenate the plant, you only need to cut off the tops, which are about 10% of the total height of the tree. After the pruning procedure is carried out, fertilizers are applied without fail, regular watering and loosening of the trunk circle are carried out.

Strong pruning should be carried out in winter or early spring, before active sap flow begins. Pruning a pyramidal poplar is a rather painstaking work, but the beauty and health of the tree depends on it.

Diseases and pests

Among the most common poplar diseases are necrosis. Also, a tree can infect certain types of tree cancer. In case of disease, the plants must be eliminated and the stumps treated with creosol and fuel oil.
Young trees are often affected by fungal diseases. Pests that lay larvae on foliage can also have a negative effect on plants. To prevent their invasion or to destroy existing ones, insecticides are used.

Landscaping applications

Among the main useful functions of poplar - purification of air from dust, gases, so it is extremely necessary to plant it in big cities. Often it is used to create compositions in parks, alleys. It can be planted both singly and en masse.

Important! If your goal is to grow trees for sale, you need to plant male and female plants next to each other - this will improve seed reproduction. The beautiful crown of pyramidal poplars makes them in demand when creating original landscapes. Also, with the help of trees, beautiful, high green protective walls are created.
Poplar, like sea buckthorn, blackthorn, mountain ash, birch, maple, linden, is the most unpretentious plant for hedges.

Home breeding methods

There are two ways to propagate poplar: seeds and cuttings. Let's consider them.

Growing from seeds

This method is rather complicated, so it is practically not used at home. If, nevertheless, you decide to try to grow poplar in this way, you will need to purchase seed, germinate it, plant it in containers with special soil and wait until seedlings appear. However, as practice shows, in most cases, this method of growing at home does not give the expected results.

Cuttings

If you want to plant and grow a pyramidal poplar yourself, it is better to propagate it by cuttings.

Rooting tree branches is quite simple - they germinate very quickly. It is necessary to place them in a container with water or slightly deepen into moist soil. If you want to grow seedlings from cuttings yourself, it is necessary in the spring, before the leaves begin to bloom, to cut off annual shoots.
They are the thinnest branches on large shoots or at the top of the trunk. The annual growth is approximately 20-30 cm long. Do you know? The oldest poplar grows in Ukraine. The girth of its trunk is more than 9 meters, and the age of the centenarian is about 200 years. It is better to plant cuttings in the spring, as soon as the snow melts. Cut shoots must be planted in moist soil, the distance between them should be 10-15 cm. A quarter of the cutting should be above the ground. After planting, it is necessary to regularly water. By autumn, the cuttings will reach the required height and will be ready for planting in a permanent place.

As you can see, there is nothing difficult in planting and caring for poplar. The main thing is to have a desire, and you can be proud that you have contributed to nature in the form of a beautiful and useful tree.

Everyone is familiar with the poplar (plant). The description of the poplar is also known to everyone, but there are some features of this tree that not everyone knows about. These are traditional ornamental plants that "live" in every settlement. They grow very fast, making beautiful green hedges. In ancient Greece, they planted squares and called them "folk" - "populus", from which the name of these plants came. All its types are ideal for both single and group plantings.

Alleys with poplars are a classic of park landscapes. One of the varieties of these plants is fragrant poplar. Description, care, reproduction of a fragrant tree - all this is discussed in this article.

What kinds of poplars exist in nature?

The genus of these plants includes 110 species. Very beautiful poplar tree! Poplar species are all somewhat different from each other, they have become simply indispensable for landscaping parks and streets. Breeders crossed them with each other, as a result of which there are now a lot of fast-growing hybrids.

Poplar species are divided into five sections:

1. Leucoid.
2. Mexican.
3. Turangi.
4. Deltoid.
5. Balsamic.

Balsamic is the fragrant poplar, which got its name from its fragrant buds. It is these fragrant trees that will be discussed further in the article.

Fragrant poplar: description

The height of fragrant poplar is about 20 m, the crown is dense, ovoid. The bark of the trunk is brown-gray, the branches are olive-gray. strongly developed, powerful roots are located close to the surface and take up a lot of space.

The buds are resinous and, as mentioned earlier, fragrant. Young shoots are round, greenish-brown, resinous and very fragrant. The leaves are leathery, oval, pointed at the top. The color of the leaves is dark green, shiny above, and whitish below with pubescent petioles. With the blossoming leaves, the color immediately blooms.

Fragrant poplar is a monoecious species very rare. The poplar begins to bloom even a little earlier than all the leaves fully bloom. Male and female specimens form spike-shaped inflorescences that differ in appearance. As they mature, they turn from erect to drooping. Among the people, such inflorescences are called earrings (earrings for men - 10 cm, women's earrings - 5 cm). At the beginning of summer, boxes ripen - poplar fruits. Very small seeds are equipped with a huge amount of the thinnest villi, this is the well-known poplar fluff.

Places of distribution

In nature, fragrant poplar is distributed in Northern China, Eastern Siberia, and Mongolia. This tree is also found in the reserves of the Far East and Siberia. It grows in floodplains and on islands, less often it can be seen in mountainous areas along small rivers and streams.

Propagation

The fragrant poplar is propagated by seed. The same method can be used in nurseries, but there is one difficulty: the seeds must be sown immediately after being harvested, and they must be ripe. In order to achieve this, it is necessary at the time when poplar fluff flies, to choose a suitable place, fence it off and water it periodically with water. The site should be placed so that a large amount of fluff is collected on it. Because of such difficulties, little is used by the seed method.

Propagation of poplar by cuttings is a way that is much easier and more convenient. For this, cuttings are used only for male specimens of poplar, and this must be done before the buds begin to bloom. For rooting, take last year's shoots up to 12 cm long with two buds. It is recommended to plant them at a distance of at least 10 cm from each other, the kidneys should remain on the surface. Immediately after planting, it is necessary to water the cuttings well, then they need to be watered daily until they grow to 15 cm, then water as the earth dries. After a year, the seedlings will be ready to "move" to a permanent place of residence.

There are poplar species that propagate by root shoots. But this method has big drawbacks. Plants grown from shoots have underdeveloped roots and are often affected by pests and diseases.

Fragrant poplar: care, cultivation

When young, the tree grows very quickly, for which it is valued when creating living fences. Poplar fragrant loves sunny places, tolerates too wet soil, is able to withstand severe frosts. The tree is quite unpretentious, but prefers fertile, well-aerated, mineral-rich soils. Poplar does not live long in cities, although it gives many shoots.

As mentioned earlier, this fragrant plant is unpretentious and does not require special care, but some rules still need to be followed in order for the poplar to please with its beauty. The land around the tree should be aerated, for this it is necessary to periodically loosen it and weed out. The soil surface must not be allowed to sod, this can lead to the death of the plant. To avoid such a nuisance, shrubs are planted next to the poplar.

Poplar does not need to be sheared. To maintain a beautiful plant, you need to remove dry branches and lower branches in time.

Diseases and pests

Like every other plant, sweet poplar sometimes gets sick and is attacked by pests from time to time. The most common diseases of these beautiful trees are some and cancer. A diseased tree must be urgently cut down, and the stump treated with fuel oil.

Young plants are often exposed In this case, silvicultural and agrotechnical measures must be applied urgently. In addition, waterlogging of the soil should not be allowed.

The list of poplar pests is quite large. There are a lot of insects that like to lay their larvae on the leaves of trees. To combat them, insecticides are used. Each pest has its own drug, so you first need to find out which enemies attacked the tree, and then look for a “weapon” against them.

Curious facts about poplar

Even children know what poplar looks like and what poplar fluff is, but besides this, there are many interesting facts about this beautiful tree:

1. Poplar leaves emit aromatic substances, thanks to which a breathtaking aroma hovers around, besides, they disinfect the air.

2. Poplar blossoms and leaves are used to make natural dyes.

3. Kidneys are used in the manufacture of "Riga Balsam" and are used in folk medicine to treat many diseases.

4. Poplars are valued for their beautiful crown shape. In addition, they have very beautiful foliage. In some species, it sometimes turns yellow or golden in autumn.

5. Poplar leaves are located very close to each other, at the slightest breath of breeze they touch and emit a very unusual and pleasant “whisper”.

Almost all types of willows and poplars growing in Russia can be propagated by stem cuttings. Only aspen and goat willow reproduce poorly with stem cuttings (aspen can be propagated by root cuttings or root suckers, and goat willow - mainly by seeds). From cuttings within one year, you can grow very large seedlings of willows and poplars - about 1 m high, and sometimes more. For growing seedlings, you can use both lignified cuttings (cut in spring from young parts of branches - last year's growths) and green ones (cut in summer from growing shoots of the current year with leaves). It is much easier to use lignified cuttings: they take root more easily and allow you to get seedlings of the desired quality and size in the first year.

Woody cuttings for planting should be taken in the spring, before the leaves begin to bloom (note that poplars and willows are among the first to open their leaves, and try not to be late with cutting cuttings). Cuttings that have already begun to blossom leaves take root worse, and as a result, seedlings are smaller and of poorer quality. For cutting cuttings, use only the growths of the previous year (they are easily recognized by the presence of buds). Cut the growths of the current year into pieces 15-20 cm long. If you want to get more seedlings, then you can use shorter cuttings - 10-12 cm or even less, the main thing is that each cutting should have at least two three buds (smaller seedlings usually grow from shorter cuttings).

Try to plant cuttings as early as possible: the sooner you do this, the better the cuttings will have time to take root before bud break, the better the young shoots will grow. Plant cuttings in rows at a fairly large distance from each other - 40-60 cm between rows and 7-10 cm between cuttings in a row: with a denser planting, the seedlings will be smaller. Bury the cuttings into the soil to such a depth that 2-3 buds remain above the soil surface (1-2 buds if the cuttings are short). If the soil is loose and the cuttings are thick, they can simply be pressed into the ground; if the soil is compacted, it is better to first make holes with a special peg. Make sure that the upper end of the cutting is pointing up (this is easy to determine by the direction of the kidneys: they are always pointed with sharp ends towards the top of the shoot). After planting, water it - this will contribute to rapid rooting, and the formation of a crust on the surface of the soil is not as scary for cuttings as it is for seeds. Water the cuttings regularly enough until the young shoots reach a height of 10-15 cm; after that, it will be enough to water only in severe drought.

Introduction.

A person's life is connected with plants that affect his health, carry a certain energy and affect the human biofield.

There are a lot of different trees and bushes growing in our village. Poplars grew near my house. These green friends, beloved by us, brought us much joy. Their huge crowns covered almost the entire area from the sultry sun. There, in the shade, there used to be calves, geese with goslings, even a cat would climb a thick, branched trunk and stretch out with pleasure, only lazily waving its tail. Yes, and we - the children loved to play under the poplars. But gradually our favorites began to turn yellow and dry, and completely disappeared. I wondered if it was possible to grow new trees. Then I studied the material about poplars and decided, without waiting for spring, to get down to business.

The purpose of my work: To study the material about the plant - poplar, its growth in nature and independently grow poplar seedlings in room conditions from cuttings. Observation and its accounting is important for conclusions.

Relevance. This project can be used as a recommendation for the cultivation of poplar seedlings, which are used for landscaping streets, in folk medicine, a source of inspiration and joy.

I . Theoretical part.

I .1.Plant - poplar . This wonderful plant belongs to the willow family. The main homeland of this handsome man is considered to be Ancient Greece. There, they planted squares and streets with them and called them “folk” - ‘populus’, so the genus of poplars began to be called by this name. These are large dioecious trees up to 40 m high, with small flowers collected in catkins, which appear before the leaves begin to bloom. The fruit is a box with small seeds, equipped with volutes in the form of a bunch of hairs (“poplar fluff”). Their negative qualities are fragility and damage by pests. A valuable quality is sufficient resistance to smoke and gases, the ability to enrich the air with phytoncides and kill pathogenic microbes.

I .2 Species of plants. The genus of poplars includes 110 species. This poplar is balsamic, white, silvery, fragrant, Canadian, pyramidal, black. Leaves glabrous or pubescent or broadly ovate. The crown can also be various ovoid, pyramidal, tent-shaped, weeping. Poplar is a long-liver, living for about 300 years. Old trees have a dark trunk, and there are growths on the bottom of the trunk. The tree has a wide, spreading crown with branches that are directed to the sides. Poplar buds are covered with resin. Most poplars are very photophilous. Poplars grow very quickly, which is not the case with other tree species.

I .3 Household use. Poplar wood is light, white, soft, well processed and used very widely for technical purposes: as a raw material for the paper industry, for producing artificial silk, making match straws, plywood, simple furniture, lumber, containers, dugout boats and much more. Wood also goes to firewood and low quality charcoal. In the southern, sparsely forested areas, wood is used for the construction of buildings; it was also used for a long time in the construction of railways as sleepers. .Purple dye is obtained from the kidneys.
In winter, the vertical position of the poplar trunk becomes noticeable, which served as a wide distribution of poplar in the landscaping of streets and alleys. Poplar is a tenacious chemical laboratory - an oxygen production plant. Absorbing all harmful waste from the air and soil, the middle-aged poplar absorbs up to 40 kilograms of carbon dioxide per hour throughout the summer. According to scientific data, for larch this figure will be 118%, for pine - 164%, for linden - 254%, for oak - 450%, and for poplar - 69one%. It has been verified that poplar fluff does not cause allergies. are seeds, and seeds are not allergens. The reason is other plants blooming at the same time.
Due to its rapid growth, it is used to produce fuel (ethanol) and heat (combustion). The poplar is growing fast.
Genetically modified poplar is currently being field tested in the US, Canada, EU, and China to improve wood quality, pest resistance, and uptake and storage of heavy metals for soil cleansing.

I .4.Properties a plants. Poplar has medicinal properties. Traditional medicine recommends that freshly blossomed sticky leaves be boiled or rubbed with butter, and applied to abscesses, cuts, boils. Ibn Sina used black poplar leaves infused in vinegar for dressings for gout. Kidney tincture is drunk for pulmonary tuberculosis, gastritis, fatigue, fatigue, as well as mixed with other herbs for cancer, various internal bleeding. Young leaves are used for soothing baths, and freshly squeezed juice from the leaves is used for toothache, with increased nervous excitability. In cosmetology, poplar is used to get rid of freckles and age spots. Poplar bark - as an antimalarial.

I .5. Mythology. In many countries, poplar is associated with mythology. One of the Greek legends tells how poplars appeared on Earth. Phaeton (the son of the sun god), in order to prove his divine origin, decided to ride across the sky on the chariot of Helios, but could not cope with the team, which, sweeping away everything in its path, rushed from the sky to Earth. Zeus struck the chariot with lightning and smashed it to prevent all life on Earth from perishing. Phaeton died in the waves of the river. Phaethon's sisters grieved immeasurably, and the Sun did not shine that day. The gods took pity on the grief of the sisters and turned them into slender, sacred trees for the Greeks - poplars.
I .6. Reproduction. Poplar is propagated by seeds and cuttings. It is not very easy to propagate the plant with seeds. Poplar seeds are small and therefore difficult to sow. After collecting the seeds, they must be immediately sown in the soil. Sowing seeds is carried out as follows: the seeds are scattered over the soil and sprinkled with water on top so that the hairs stick together and the seeds remain on the surface of the soil. It is not necessary to pour soil over the seeds. If the weather is dry, then the seeds are covered with a film. Poplar can also be propagated by cuttings. It is better, and much easier, to use lignified cuttings for growing, because they will take root faster and produce developed seedlings in the first year. Harvest cuttings in the spring, even before the leaves bloom. You can cut cuttings only at the branches of the last year. Each cutting must have at least 2 buds. Planted cuttings as early as possible and in rows. A distance of 10 cm must be observed between the cuttings. The cuttings are deepened so that the buds remain above the soil surface. Immediately after planting the cuttings in the soil, watering is carried out so that the cuttings take root quickly. The plants are watered every day until the young shoots grow up to 15 cm. And in the future, the shoots are watered only as needed.

I .7. Tree pruning . Poplars lend themselves well to shearing and pruning and easily restore the crown. Immediately after any trimming, all wounds with a diameter of more than 2.5 cm should be covered with garden putty or painted over with oil paint on natural drying oil. Pruning should start at an early age and be done annually. Cut off 1/2 the length of the shoot, leaving 10-20 cm on the tree. The shape of the crown should be even, without protruding shoots. Strong pruning is carried out in winter or early spring, before the start of sap flow. A powerful shoot is formed from the stump, which should then be formed. When rejuvenating plants, only the tops are cut off, that is, about 10 - 15% of the height. After a strong pruning, it is necessary to fertilize, regularly water and loosen the near-trunk circle. Shelter for the winter is not required. Frost-resistant.

II .Practical part.

II .1 Taking cuttings poplars . Lignified cuttings of different sizes 15-20 cm were cut, so that each cutting had several live buds, especially in its upper part (the one that was closer to the top of the shoot. (Appendix). The cuttings lay in the room for a day at room temperature. Then they were placed in a jar of water (Appendix).

II .2. Growing seedlings. Care for them. After the appearance of the roots, the cuttings were planted in pots. The optimal composition of the soil for this plant is as follows: three parts of the earth, which in equal shares consists of sod, leaf and humus, and one part of sand. The size of the pot for cuttings is twelve to sixteen centimeters in diameter. The soil was compacted and watered. The greenhouse was placed in a warm and bright place. (Application). A month after planting, the cuttings increased by 12 cm. (Appendix). Poplars are unpretentious, they easily adapted to the conditions of the house. Before planting the cuttings in the ground, they were hardened. To do this, pots with cuttings were taken out daily for 2-3 hours under a canopy, protected from wind and direct sunlight.

Hardened new plants were planted in the ground in early spring. (Application). Watered as needed so that the soil was saturated to the depth of the roots.

Conclusion.

Having studied the material about poplar, the seedlings were grown in room conditions.

During the period of observation and cultivation of a new plant, we made the following conclusions:

1. We have experimentally shown that it is possible to grow poplar seedlings at home. The plant has adapted to home conditions. Proper care of it contributes to good development and abundant root formation.

2. The best propagation of poplar is cuttings.

3. Plants grown from cuttings are stronger, have a good root system, which is a necessary condition for survival.

4. Poplar is an amazing plant that is used for landscaping village streets and, in addition to beauty, has unique healing properties.

The materials of this work can be used for practical application in the reproduction and cultivation of poplar at home, which is used for landscaping and in folk medicine. The poplar is a decoration of the village, a source of inspiration and joy.
