How to plant poplar trees
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.

Superior hybrid poplar trees are a popular hardy, low-maintenance option for fast-growing shade trees or privacy screens with visual interest in the fall.
Reviews by This Old House Reviews Team 07/22/2022 12:00 am
Superior hybrid poplar trees are an excellent choice for anyone trying to grow a shade tree or living privacy screen quickly. These towering trees can grow 5-8 feet per year until reaching a maximum height of around 50 feet.
Superior hybrid poplars are so low-maintenance that they’re practically hassle-free trees, disease-resistant and able to grow in a wide range of soils and light conditions. But with Superior hybrid poplars, it’s not all about practicality—in fall, the foliage is a beautifully vivid yellow.
Superior Hybrid Poplar Trees at a Glance
- Extremely fast-growing
- Excellent privacy screens
- Spectacular yellow leaves in fall
- Produce no cottony seeds
- Attract deer
Superior hybrid poplar trees grow in a pyramidal form, with triangular leaves that are 3-6 inches long and silvery-green on the top, with paler green undersides. In fall, the foliage is brilliant yellow, and their leaves drop in winter.
The trees grow to be 40-50 feet tall with a spread of 30 feet. They reach the height quickly, increasing in height by 5-8 feet per year.
|Appearance||Pyramidal form with 3-6 inch long, triangular leaves that are silvery-green on top with pale green on undersides that turn brilliant yellow in fall|
|Hardiness Zones||Zones 3-8|
|Type of tree||Deciduous|
|Sunlight requirements||Full sun to partial shade|
|Soil composition||Highly adaptable, with preference for acidic or alkaline wet soils|
USDA Hardiness Zones indicate the regions where plants can grow based on minimum winter temperatures. Superior hybrid poplars grow in Zones 3-8, across almost the entire country. They do not grow in areas like the coldest parts of Minnesota, or the hottest parts of southern Texas and Florida.
The best time to plant a Superior hybrid poplar is during spring or fall. We recommend following these steps:
- Choose a planting site with full sun or partial shade.
- Clear away any turfgrass, weeds, or debris.
- Dig a hole that is the same depth as the root ball and three times as wide.
- Remove the Superior hybrid poplar from its container and spread the roots gently with your fingers or a small spade.
- Begin backfilling the hole, then stop halfway and add water. Once it drains away, finish backfilling the hole.
- Apply a 2-3 inch layer of mulch around the root zone to help conserve moisture, being careful not to let it touch the trunk.
Superior hybrid poplar trees are very low-maintenance and adaptable to a wide range of soils and levels of sunlight.
Sun and shade
These trees flourish in full sun, or at least six hours of direct, unfiltered sunlight per day. However, they can also grow in partial shade.
Superior hybrid poplar trees are highly adaptable to a wide range of soils, with a preference for alkaline, acidic, and wet soils.
These trees require about an inch of water per week, accounting for rainfall in the forecast. They may need more frequent watering during hot, dry spells in summer.
Do not fertilize your Superior hybrid poplar tree during planting or during the first season after planting. Feed your tree annually in the fall, using ½ pound of fertilizer with a ½-inch trunk diameter at the base. If the tree is larger, use one pound for each inch.
Superior hybrid poplar trees do not require any pruning, since they naturally grow into an oval shape. If you want to prune a branch, do so in late winter or early spring before new growth begins.

tree description, planting and care, species, cuttings
The poplar plant is the most common tree in Russia. It is most often used for landscaping both rural and urban streets. To date, the fast-growing rather spectacular poplar has lost its former popularity among gardeners. It's all about the abundant fluff, which can be a real problem for a summer resident. However, professional landscape designers believe that this is a rather interesting plant that deserves special attention.

Features of poplar
Poplar belongs to the class of dicotyledonous deciduous plants, while it is part of the willow family. The plant is characterized by rapid growth during the first 40-60 years. After that, it begins to grow more slowly. On average, the life expectancy of poplar is from 60 to 80 years. However, there are specimens whose age is from 120 to 150 years.
This tree can reach a height of about 40 meters, and its trunk across - up to 100 centimeters. The shape of the crown directly depends on the species and can be pyramidal, ovoid or spherical. The surface of the trunk is covered with gray bark, which may have a light black or brown tint. Over time, a large number of cracks form on the bark. The surface of the gray branches is smooth and even, and it has a delicate olive tint.
The root system of poplar is quite strong and well formed, often superficial. Over time, growing roots go beyond the border of the crown. Alternate green leaf blades may be lanceolate or ovoid. The surface of the foliage is covered with a well-defined reticulate venation.
This tree is characterized by rapid growth and development. Its wood has found application in both the timber and furniture industries. The first time the poplar forms seeds only after it is 10-12 years old. Flowering begins simultaneously with the opening of leaf buds. In some cases, the tree blooms even before the opening of the leaf blades. Hanging spike-shaped inflorescences are formed on the branches, which are called earrings. After pollination, a single ovary is formed. When the poplar fades, a fruit is formed in place of each flower, which is a box that has from 2 to 4 wings. Over time, they open up. The box contains oblong very small seeds 0.1–0.3 cm long. In 1 gram of seeds, there are about 1 thousand pieces. Each of the seeds has a whole bunch of thin hairs, thanks to which, with the help of the wind, they can “fly away” a decent distance from the parent tree. This phenomenon was called "poplar fluff". Already next spring, young shoots can be found at a distance equal to several kilometers from the mother plant.

Types of poplars with photos and names
The poplar genus includes about 90 species. However, most of the species are wild. However, there are varieties of poplar that were born thanks to the work of breeders. Such hybrids combine endurance and unpretentiousness, as well as the decorative qualities of wild plants.
White poplar (Populus alba)
People also call this species Belle, silvery, snow-white. Most often, such a plant is found in Europe and Asia. Its height can reach up to 30 meters. This species is long-lived, its age can vary from 65 to 400 years. Its trunk is thick, but not too high. The crown is spherical. Only at a height of 200 cm from ground level is there an active growth of branches. The surface of the gray bark is smooth and may have a pale green tint. In very old plants, the bark becomes almost black.
Small silvery buds form on the branches. The shape of the leaf plates is deltoid. The front surface of the foliage is green, and the underside is pale silver. Flowering is observed in the spring months. At this time, elongated inflorescences appear on the branches. Seeds look like cotton wool, which is easily carried over long distances by gusts of wind. The most active flowering occurs in the second and third weeks of May, and the full maturation of seeds occurs by July.
Canada poplar (populus deltoides) or deltoid
This variety is obtained artificially. This tree looks very similar to the deltoid poplar. Its trunk is very high, and the crown is spreading. In spring, relatively large brown buds form on the branches, the surface of which is covered with a thick layer of gluten.
The shape of the sheet plates is almost triangular, while there are small teeth on the edge. The leaves are up to 7 cm long and up to 10 cm wide. They have long petioles (about 30 mm).
The beginning of flowering falls on the period of bud swelling. Long earrings are formed on the branches. The most active tree begins to bloom in April. Seed formation is observed in the first summer weeks, after which they are carried by the wind in different directions. This variety is the most vigorous among all poplars.
Two types of fast growing California poplar

Black poplar (Populus nigra)
This species can be found in nature in Western Siberia, Central Asia, the Crimea, and also in the middle latitudes up to Perm. Such a strong tall plant prefers to grow on river banks and in light forests, while it loves loose soil.
In young trees, the greyish bark has a smooth surface. However, over the years, it turns almost black and becomes covered with many cracks. Dark green leaf plates are triangular or diamond-shaped. This plant is drought and frost resistant. Poplar does not impose special requirements on the soil, but fertile land rich in humus is best suited for it.
Sweet poplar (Populus Suaveolens)
This species originates from the Far East, and it is most widely distributed in nature in the eastern part of Siberia. Another such tree can be found in Mongolia and Northern China. As a rule, the height of the trunk does not exceed 20 meters. In a large number of cities in Russia, you can meet many alleys from this already familiar plant.
The branches of this not too tall but powerful tree grow at an angle of 70 degrees. This contributes to the formation of an unusual oval-shaped crown, which can reach up to 15 meters in diameter. Young branches are covered with smooth and thin bark of a pale yellow or greenish-gray color. Over the years, aging of the bark is observed, while it becomes covered with cracks. The length of the oval sheet plates, narrowed towards the top, is about 10 centimeters, while the width is up to 6 centimeters. The color of the foliage can be very different: from greenish to olive. The reverse surface of the plates has a slight silvery tint. A network of veins is clearly visible on the surface of the leaves.
This species does not impose any special requirements on the soil. However, it grows best on clay soil or black soil. It has high winter hardiness, poplar is able to withstand frosts down to minus 40 degrees.
The beginning of the flowering period falls on the opening of the leaf blades. By the second half of June, active flowering is observed, and a lot of poplar fluff is formed, which scatters in different directions.
Pyramid poplar (Populus pyramidalis)
This light-demanding poplar is one of the most vigorous. The height of the trunk of an adult plant can vary from 35 to 40 meters. The average life expectancy is about 300 years. This plant is most widely distributed in Russia, Central Asia, Ukraine, the Caucasus and Italy.
This tree grows best in a sunny position with neutral to slightly acidic soil. During the first 10 years, the development and growth of poplar occurs most rapidly. Strong stems grow at an angle of 90 degrees relative to the main stem. Due to this, a narrow crown is formed.
A large number of small cracks are located on the surface of the dark bark. In an adult plant, the trunk in diameter can reach more than 100 cm. The surface of young branches is covered with olive or greenish smooth bark. Immediately after the opening of the first leaf plates, elongated inflorescences appear on the branches, consisting of small flowers.
The upper side of the foliage is bright green and the underside is a lighter shade. On the edge are small teeth. Such a poplar feels great in urban conditions, while the exhaust of enterprises and cars does not harm it.
Laurel poplar (Populus Laurifolia)
The maximum height of this tree is about 18 meters, it is found in Siberia. This species grows well in shady areas. It is distinguished by a wide spectacular crown of a tent-like shape.
The trunk is adorned with many stems that are covered with dense foliage. It is bright green and has a lanceolate shape and short petioles. At first glance, it may seem that the leaf plates grow in bunches. Such a poplar does not develop very quickly, but it tolerates gas pollution on the streets of the city well.
A tree such as poplar is most widely distributed in nature in the northern hemisphere. Differs in the Holarctic type of distribution. This plant comes from China, or rather from its subtropical region, from which poplar grows to the boreal zone. On the territory of America, it can be found in the southern part to Mexico, and also in Canada and other regions.
Most species in the wild prefer to grow near rivers on slopes, and are not harmed by high humidity. The tree grows well in light areas, and it develops best in the area where spruce or oak used to grow. The soil can be any, most importantly, it must be fertile and breathable.
Planting and caring for poplar
In order for poplar to grow spectacular and healthy, it is necessary to choose the most suitable site for its planting. This crop grows best in a sunny area. In this regard, it is better not to choose shaded places for planting a seedling.
It is recommended to choose a draft-free location. You should also immediately think about the place where the broken branches will fall.
Poplar is undemanding to the composition of the soil. However, it grows fastest on loose, fertile soil, while optimal moisture must be ensured. It is recommended to plant seedlings in spring, because when planted in autumn, seedlings have very weak immunity. Often the tree is affected by infectious or fungal diseases.
A distance of at least 100 cm should be observed between seedlings. As the root system of poplar is deep and well developed, the planting pit should reach a depth of about one meter. At the bottom of the prepared hole, make a good layer of drainage, which will prevent stagnation of fluid in the roots. Also, any mineral complex fertilizer, for example, nitroammophoska, should be added to the pit. Immediately after planting, the seedling must be tied to a previously prepared support. The planted tree needs to be watered with plenty of water, then the trunk circle is covered with a layer of mulch, for example, sawdust or peat.

Caring for poplar
This tree is easy to care for and undemanding. For normal growth and development, timely loosening, fertilization, watering and pruning are enough for him.
Pruned poplar at the beginning of spring or late autumn. Remember that this procedure can be carried out only when there is no sap flow. There are two types of pruning:
- Shaping . Initially, the seedling actively grows 1 stem vertically upwards. Therefore, to obtain a spectacular crown, regular shaping pruning will be required. Remember that the columnar type cannot be trimmed.
- Sanitary . This pruning is carried out annually. To do this, cut out all injured, dried and dead stems.
When the plant is 30-35 years old, it is recommended to rejuvenate pruning or crowning. In this case, 1/5 of the crown should be cut, while the topmost branches are removed. All places of cuts should be smeared with garden pitch. Next, carry out watering and top dressing of the plant. After some time, young shoots form on the trunk, which can again be used to form a crown.
As a rule, only young poplar trees need watering during the first few years of their growth. The soil under the tree is moistened three times a month. At the same time, at least 25 liters of water are poured under one plant. During the dry season, the tree is watered more often.
During the first year of growth after planting, do not forget to regularly loosen and weed the surface of the tree circle. You need to loosen the ground every time the poplar is watered, and even when the snow cover completely disappears. When the plant is six years old, the earth can no longer be loosened. It is recommended to sow lawn grass in the near-stem circle.
Top dressing is carried out systematically. The first application of the nutrient composition is carried out immediately after planting the tree. Further, it is systematically fed with fertilizer containing nitrogen.
Two methods are used for poplar propagation: seeds and cuttings.
Growing from seeds
The seed method of poplar propagation is quite difficult, so it is not popular with gardeners. Seedlings can only give fresh or stratified in a special nursery seed material. Every day, matured seeds are increasingly losing their ability to germinate. And after only 7 days, they will never be able to ascend again.
If stratified seed material is used for sowing, then a container is prepared for this, which is filled with loose soil consisting of peat and sand. From the moment of sowing to the appearance of seedlings, about 4 weeks should pass.

While the shoots are young, they easily root. They quickly take root and do not need any special care and conditions. For the preparation of cuttings, one-year-old branches are chosen, while they are cut at the beginning of the spring period. Cuttings can be prepared in late autumn. Thin branches about 100 cm high are well suited for this. Kidneys must be present on the cuttings. Cut branches must be cut into several pieces with a length of 17 to 20 centimeters.
For rooting, cuttings are planted at the beginning of the spring period (when the snow cover disappears) or in autumn (after the end of leaf fall). The segments should be planted in moist soil, while about 70–80 mm of the cutting should remain above the ground.
If the cuttings are properly cared for, then young stems will soon grow from the buds. By the onset of September, the height of the young tree should already be about 100 cm. After 12 months, the young tree is transplanted to a permanent place.

Diseases and Pests
Poplar is resistant to many pests and diseases. However, it may suffer from:
- tree cancer;
- various small pests that suck plant sap or eat young leaves (eg psyllid, aphids, moths).
To save the plant, it is necessary to treat it with a suitable chemical agent. For example, Karbofos is used to destroy poplar-spruce aphids. The gall psyllid is destroyed with an intraplant insecticidal agent. If the plant has a lot of caterpillars of the tailed moth, then organophosphorus insecticidal preparations are used for treatment. From scab and rust, oxygen sulfur should be used.
Significance and use
Poplar wood is widely used for industrial purposes. It is distinguished by its softness and lightness. The wood is used for the production of: rayon, lumber, boats, paper, plywood, furniture, etc.
This wood has a low thermal conductivity, but it is still used for firewood and charcoal, which are of poor quality. The leaves are used to make yellow dye, while the buds are used to make purple. Young shoots, as well as stems with foliage, are used as food.
Healing properties of poplar
It has long been known that poplar has medicinal properties that are used in alternative medicine. At the same time, the stems, foliage and buds of poplar are quite widely used. Benefits:
- The bark contains many tannins, alkaloids and glycosides. Decoctions are prepared from it, which improve the condition of the digestive and nervous systems.
- Leaves are used to make an infusion with wound healing properties.
- A tea is made from the kidneys, which has a tonic and anti-inflammatory effect.
- Ointments and decoctions are prepared from leaves and buds, which are used for depression and insomnia.

Poplar in landscape design
Poplar is distinguished by endurance and unpretentiousness. It can grow normally on depleted soil, and it is also not afraid of frost, drought and heat. Large poplar forest parks can often be found in regions with a harsh climate. However, large plantings are quite difficult to care for.
Poplar has a dense, spectacular crown, giving partial shade. Decorative varieties are often used to create spectacular group plantings. Good poplar neighbors are thuja, acacia and juniper.
With the right planting of seedlings, you can create a real "living" wall. The average height of such dense spectacular hedges is 150–250 cm. The disadvantage of such hedges is that their lower part is bare. In this regard, it is recommended to use a two-row planting. In the foreground, low-growing crops are planted, for example, shrubs.
Allergy sufferers and people with bronchial asthma oppose the widespread use of such a tree in landscape design.
The disadvantage of this crop is the need for regular pruning, because it is characterized by rapid growth. In place of the cut stems, after a short time, a young shoot is formed, which is used to form a new crown.
Roads and streets are often landscaped with this tree, and it can also often be found in an industrial area. The fact is that it quickly cleans the air of harmful components. In order to exclude the appearance of poplar fluff, only males are planted.
To create a spectacular green frame near the building, as a rule, it is enough to choose the right variety and size of poplar. To create beautiful compositions, poplar plantings are diluted with a variety of shrubs, chestnuts, lindens, maples or birches. Poplars are planted in a row to highlight the boundaries of squares, parks, gardens, etc. Such a tree creates a pleasant shade, and also adds a decorative effect to the composition.

Topol Popol much fluff and brittleness, when branches fall on the roof in any wind, and undergrowth breaking through the asphalt. Attempts to grow only male plants that do not bear fruit and do not scatter fluff led to the fact that the latter began to change sex and began to bear fruit.
However, white poplar Richardii favorably differs from wild poplar - it never reaches gigantic sizes, grows very weakly and practically does not give root shoots. But the main difference is in the unique color of the sheet. Its underside is pure white, like a regular white poplar , and its upper side is not dark green, but lemon yellow. The plant recovers well when planted on a stump, it can be grown using the coppice culture method. In this case, the height will be no more than 1–1.5 m, which means that it may well create an accent in flower beds. On coppice shoots, the leaves are much larger (up to 8 cm) and denser. White poplar 'Richardii' is spectacular not only near, but also at a distance, especially in windy weather, when the swaying leaves shimmer with yellow-white flashes. It tolerates prolonged flooding, and this is a problem in many areas in spring and autumn.
Another interesting but rare poplar large-leaved poplar ' Aurora ' (sometimes called Ontarian poplar ) - reaches 7–9 in Europem in height. In our climate, it is lower, but this is for the better - as a result of freezing, coppice shoots begin to grow, which carry large leaves (up to 10 cm long) at the ends, covered with cream and pink spots. At the end of summer they become light green. From afar, the leaves give the impression of large inflorescences crowning the shoots. Large-leaved poplar ‘Aurora’ is especially effective in coppice culture, which, in addition, excludes its dispersion over the territory.
Stands alone quivering poplar , or, as it is often called, aspen . Indeed, aspen belongs to poplars and is also perceived as a garbage tree. It is possible that the typical aspen is quite actively spreading by shoots, but this ability was not noticed in its variety ' Erecta '. This is a vertical plant that immediately adds color to the site. It grows quite quickly (growth up to 1 m per season) - it cannot be compared with the pyramidal forms of oak or juniper. In autumn, the foliage turns honey-yellow tones, which in itself is interesting for verticals - there are no analogues. At the same time, aspen is frost-resistant and unpretentious. She suffers only from severe drought.
