How to care for rosemary tree


How to Care for a Rosemary Tree

By Erin Marissa Russell

Rosemary trees are a common holiday gift for gardeners, home cooks, and those new to caring for plants alike. These little trees are easy to care for and make a handsome addition to the home or outdoor garden as well as being easy to put to use in the kitchen. But if you’re receiving a rosemary tree for the first time or have cared for one unsuccessfully in the past, you’re probably wondering how best to care for your rosemary tree. We’ve got you covered with this guide to keeping your rosemary tree in top condition throughout the year.

Prune Your Rosemary Tree as Needed to Maintain its Triangular Shape

When you first receive your rosemary tree, its shape will be well defined, but as it grows, the edges will get shaggy and uneven. Every three to four weeks, use clean, sterilized shears to clip off the branches that are out of bounds. Trim the branches back all the way to where they meet the trunk of your rosemary tree. If you leave a small piece of the branch behind, the tree can become stressed trying to care for it, so make sure to clip the branches as close to the trunk as possible. After you’ve pruned your rosemary tree, mist it with a spray bottle full of water.

Find the Right Location for Your Rosemary Tree

Your rosemary tree needs plenty of sunshine to stay healthy. You can either keep it indoors in a sunny windowsill year round or move it to the outdoor garden when the weather is warm enough. A south-facing window is normally the best indoor spot for a rosemary plant, as long as it doesn’t get too hot. 

Just make sure that the spot in your outdoor garden where you place your rosemary tree has soil that drains well, if you’ll be removing the tree from its container and planting it in the ground. This plant even loves to grow in sandy soil, but it won’t tolerate too-wet soils that keep its root system wet. And even outdoors, rosemary needs a spot with full sun—that’s at least six to eight hours of sunlight each day. It can stay in the outdoor garden from the spring to the fall season. 

Rosemary also requires good air circulation, so whether it’s indoors or out, make sure that your rosemary plant isn’t too sheltered from the wind or cramped against other plants that will keep air from circulating around it. Whether you keep your rosemary plant in its container or put it in the ground, it will need to come back indoors before the first frost in your area, so you’ll need to put it into a container if it’s been growing in the ground. More on that in the next section.

If You Keep Your Rosemary Tree Potted, It Will Need a Larger Container

If you move your rosemary plant into the outdoor garden permanently, it will be happy to grow in the ground and keep getting larger. But if you keep it in the pot, eventually the plant will need to be upgraded to a larger container. Every year in spring, choose a container that’s the next size up from the one your rosemary plant is currently growing in. Signs that a rosemary plant is ready for a new container include if the plant has recently broken out in lots of new growth or if you just can’t seem to get the plant well hydrated enough.

Gently remove the plant from its current container. Fill the new container about halfway full with potting soil, then place the plant inside the new container on top of the new soil. Use more potting soil to fill in around the edges of your rosemary tree, making the soil firm enough that the tree will stand up in place securely. Water the plant deeply (until the moisture drips from the container’s drainage holes) as soon as you are done repotting it.

You can avoid the need for larger containers and keep your rosemary tree at the same size instead if you prefer. To do this, you’ll need to prune the roots of your rosemary tree, slicing off a few inches from the root ball of your plant, both at the bottom and the sides. Then simply place the rosemary tree back in its current container and re-pack the soil around it.

Keep Your Rosemary Tree Well Hydrated

Rosemary plants can be harder than others to keep well watered, as rosemary won’t droop, wither, or show other signs that it is low on water until the situation is really dire. Although rosemary plants are tolerant of drought, they will still need some watering from the gardener. The basic guideline is to water your plant deeply once every week or two. Watering a plant deeply means watering until the moisture drips from the drainage holes of the container. If your plant is growing in the soil outdoors, leave the water on near the base of the plant until the moisture has soaked several inches into the soil. However, don’t water your rosemary tree again until the soil where it is growing is dry to the touch. Rosemary plants are sensitive to their root system getting too wet when the soil they grow in is waterlogged. Soil that stays too wet can lead to root rot, so you want to be sure to let the ground dry out between your watering sessions.

Bring Your Rosemary Tree Indoors During Cold Weather

Rosemary trees are tolerant of hot weather and high temperatures, and they also perform well in a wide range of humidity levels. However, weather that gets too cold can be fatal for these plants. Rosemary is usually hardy until the temperature reaches 30 degrees Fahrenheit (-1.1 degrees Celsius). That means that before the first frost arrives in your area, you’ll want to remove your rosemary tree from the outdoor garden and bring it back indoors. If it has been growing in the ground, you’ll probably need to get a larger container for the plant than it used the previous year at this point. If you repotted your rosemary tree in the spring and have kept it in its container while it was outdoors, then all you will need to do is move the tree inside when the weather cools down.

Give Rosemary Trees a Boost in Spring with Fertilizer

In the springtime, it’s a good idea to feed your rosemary tree with a fish or kelp emulsion to help foster lots of new growth and keep your tree healthy. Every once in a while, you can also spray your rosemary tree with the same fertilizing fish or kelp emulsion to keep it growing strong. It’s an especially good idea to do this if you notice that your tree is looking a little under the weather.

These few guidelines are all you need to know to take good care of your rosemary tree and keep it in excellent shape. Even if you move your rosemary tree into the outdoor garden, if you maintain its watering and pruning schedule, you should be able to put the rosemary tree back into its container when next Christmas rolls around so you can bring it back indoors. Some people use their rosemary trees as miniature Christmas trees. If you do this, just be careful not to use lights that get too hot (large lights tend to do this) or to keep your tree too near to candles or other Christmas decorations that can cause fires.

How to Plant Rosemary

When to Plant

Rosemary is best planted in the spring once the weather has warmed and there’s no frost in the forecast. Containers indoors generally can be started at any time of year.

Selecting a Planting Site

Rosemary grows best in a sunny spot that has soil with sharp drainage. Make sure no taller trees or shrubs in the area are so close that they will shade the rosemary. Rosemary also grows well in containers both outdoors and indoors, as long as it can get enough light.

Spacing, Depth, and Support

Space rosemary shrubs at least 2 to 3 feet apart. Plant seedlings and nursery plants at the same depth at which they were growing in their previous container. Seeds should be just barely covered with soil when planting. A support structure is typically not necessary for this shrub.

Rosemary Plant Care

Light

Rosemary likes full sun and does not tolerate shade. This means it requires at least six hours of direct sunlight on most days. A south-facing window is ideal for indoor growth, and grow lights are often necessary to provide supplemental light. Bring indoor plants outside in warm weather to allow them access to natural sunlight. Inadequate light can cause leggy and weak growth.

Soil

A well-draining sandy or loamy soil is best for rosemary. It doesn’t grow well in heavy clay and wet soils. A slightly acidic to neutral soil pH is ideal (6.0 to 7.0).

Water

Rosemary shrubs have good drought tolerance once they are mature, and it’s better to underwater rather than overwater them. Allow the top few inches of soil to dry out between waterings, and then water so that the soil is evenly moist but not soggy.

Temperature and Humidity

This shrub likes warm weather and moderate humidity levels. Most rosemary varieties can’t survive temperatures below 30 degrees, but they have good heat tolerance. They prefer temperatures between 55 degrees and 80 degrees. Moreover, high humidity can lead to rot and fungal issues, especially if there isn’t enough air circulation around the plant.

Fertilizer

Rosemary is not a heavy feeder. Mixing compost into the soil at the time of planting can help to give the shrub a healthy start. Then, using a balanced liquid fertilizer, following label instructions, will continue to promote quality growth.

Pollination

Rosemary shrubs self-pollinate and attract bees and other pollinators to the garden. Bring indoor plants outdoors in warm weather when their flowers are open to allow the blooms to naturally pollinate.

Types of Rosemary

There are several types of rosemary to grow, including:

  • ‘Arp’: This plant has light green foliage with a lemony scent, and it’s known for its cold tolerance.
  • ‘Golden Rain’: This plant stays compact at 2 to 3 feet high and wide, and it features yellow markings on its foliage. 
  • ‘Albus’: The trademark of this cultivar is its white flowers.
  • ‘Prostratus’: This cultivar has a low, spreading growth habit at around 2 feet high and 2 to 3 feet wide.

Rosemary vs. Lavender

Rosemary and lavender are similar in appearance. Both are shrublike with woody stems, and they feature aromatic leaves that are long and thin. However, rosemary plants generally grow larger than lavender. Rosemary blooms form among the foliage while lavender blooms rise above the foliage on flower spikes. And lavender has a lighter and more floral taste and aroma than rosemary.

Harvesting Rosemary

Rosemary can be harvested at almost any time of year, though spring and summer are when it grows most actively. And the leaves are most flavorful and aromatic just before the plant blooms. To harvest, use pruners to cut off 4- to 6-inch stem tips.

Use fresh rosemary sprigs or leaves in cooking as you like. Or hang the stems upside-down in a dry, cool, well-ventilated area for drying, which should take a couple of weeks. Once the stems are dry, strip off the leaves and keep them in an airtight container in a pantry.

How to Grow Rosemary in Pots

Growing rosemary in pots allows you to bring it indoors during cold weather. You also can keep containers on a patio or deck near your kitchen for easy access while cooking. Select a pot that’s slightly larger than the plant’s root ball. Make sure it has drainage holes. An unglazed clay container is best to allow excess soil moisture to evaporate through its walls.  

Pruning

Prune rosemary as necessary to shape its growth after the plant is done flowering. Rosemary responds well to pruning and can be trained into topiary shapes. But don’t prune off more than a third of the plant at a time, as this can stress the shrub and leave it vulnerable to diseases and pests. 

How to Grow Rosemary From Cuttings

If you would like to propagate your own rosemary plant, the best option is to start with a cutting. Not only is this an inexpensive way to get a new plant but taking cuttings from a mature plant can help to promote more branching and bushier growth. The best time to take a cutting is in the spring or summer. Here's how:

  1. Cut a piece of healthy stem that’s a few inches long. Choose new softwood growth for best results.
  2. Remove the leaves on the lower portion of the stem, leaving at least five leaves. 
  3. Dip the cut end in rooting hormone.
  4. Plant the cutting in a moist soilless potting mix in a small container that has drainage holes.
  5. Place the container in a warm spot that has bright, indirect light. Mist the cutting daily, and make sure the growing medium doesn’t dry out.
  6. In about two to three weeks, gently tug on the stem to check for roots. If you feel resistance, you’ll know roots have developed. After that, the cutting is ready for transplanting.

How to Grow Rosemary From Seed

Growing rosemary from seeds can be difficult because they don't germinate easily and they often do not grow true to their parent plant. If you wish to try growing rosemary from seed, plant several more seeds than the number of plants you hope to grow. Start seeds around three months prior to your area’s projected last frost date in the spring. Take these steps:

  1. Scatter the seeds in a tray filled with moist seed-starting mix, just lightly covering them with the mix.
  2. Cover the tray with plastic wrap to trap moisture, and make sure the mix doesn’t dry out.
  3. Place the tray on a heat mat to keep the soil between 80 degrees and 90 degrees Fahrenheit.
  4. As soon as seedlings appear, remove the plastic wrap, and place the tray in bright light.
  5. Once seedlings are around 3 inches high, move them to individual pots or outdoors if the weather is warm.

Potting and Repotting Rosemary

Use a light, well-draining potting mix when growing rosemary in a container. Plan to repot every year into one container size up, using fresh potting mix. The best time to repot is in the spring. Gently loosen the plant from its previous container, and situate it at the same depth in the new one, filling around it with soil.  

Overwintering

Bring rosemary indoors well before any frost is predicted in the fall forecast. Keep it in a warm room and away from any drafts or drying air from heat vents. Continue providing it with at least six hours of sunlight per day via a bright window and/or grow light. And slightly back off on watering, though don’t allow the soil to fully dry out. Once frost is out of the forecast in the spring, the plant can go back outside.

Common Pests and Plant Diseases

High humidity and poor air circulation can result in powdery mildew—a white, powdery fungus—on rosemary plants. Powdery mildew typically won't kill a plant, but the disease will weaken it. To prevent powdery mildew, make sure the plant's soil isn't too wet, and provide a few feet of space around it for airflow.

Also, be on the lookout for aphids and spider mites, especially on indoor plants. Use an insecticidal soap as soon as you spot an infestation to prevent it from spreading.

Rosemary officinalis (ordinary, wedding flower, dike, bride's dress, incense grass) - evergreen fragrant subshrub of the Lamiaceae family native to the Mediterranean, Western Europe, Turkey and North Africa, reaching a height of up to 2 m. The literal translation of the name of the plant from Latin is “sea dew”: according to legend, a few drops of sea moisture fell on rosemary from Aphrodite emerging from the waves of the sea, and the passion-ridden plant turned bluish and took on a strong camphor smell.

The themes of love, eternal youth and devotion associated with rosemary have run like a red thread through the cultures of many peoples. So, the ancient Greeks and Romans attributed to rosemary an increase in vitality, an improvement in memory and potency; in medieval Europe, the plant was considered a symbol of marital fidelity and at the same time, oddly enough, the eternal memory of the dead; in the late Middle Ages, an unknown perfumer created the famous "Water of the Hungarian Queen", thanks to which a certain 72-year-old representative of the Hungarian ruling dynasty charmed youngsters indiscriminately and actively replenished financial assets at the expense of the older wealthy population.

Rosemary is rich in trace elements, borneol, essential oils, camphor, cineole, plant resins, tannins and acids. It has an aroma somewhat reminiscent of the smell of pine, its leaves have a pronounced bitter taste, so you need to use this spice in a dosed and correct way. Rosemary is suitable for roast lamb, pork, goose, duck and fish. The famous French vegetable stew "Ratatouille" also includes this classic spice. Often, to give an exciting aroma to dishes cooked on an open fire, smoldering coals are sprinkled with leaves and sprigs of rosemary. In combination with other spices and components, rosemary can not only shade, but unusually change the taste of seemingly thoroughly familiar dishes: for example, a perfect combination of eucalyptus, bay leaf and rosemary; rosemary is perfectly complemented by garlic, capers and lemon zest - in general, a whole field for your culinary experiments.

Rosemary is a good immune stimulant and has antioxidant, anti-inflammatory, tonic, wound healing and choleretic properties. Rosemary is contraindicated in pregnant women, young children, as well as people with hypersensitivity of the skin, suffering from epilepsy, convulsions and hypertension.

In general, this odorous southerner is unpretentious in care, but, like any individual, requires a special approach, “promising” in return medicinal help and unbroken taste sensations, so go for it!

Recommended cultivars

  • 'Prostratus' - a variety with soft shoots creeping along the ground, height 15-20 cm.
  • 'Roseus' is a variety with large pink flowers, used in garden/greenhouse landscaping in warm climates.
  • "SevernSea" - a variety up to 50 cm in height, used in garden landscaping in warm climates.
  • "Albiflorus" - a variety with large and fragrant white inflorescences, excellent for growing at home.
  • Rosemary ordinary, varieties "Tenderness", "Rosinka", "Veshnyakovsky Semko". It will be discussed below.

Growing equipment: planting container 15 cm deep; clay, ceramic or terracotta pots Ø35 cm and 40 cm high with a drainage layer of 15% of the volume (for example, expanded clay PETER PEAT of the VITA line) and holes at the bottom; drip tray for excess water; picking peat pots 7x10 cm; small scoops and rakes; phytolamp; prepared nutrient soil.

Seed preparation

If you decide to grow rosemary from seed, the best time to do so is early March. It is best to purchase encrusted rosemary seeds ready for planting in advance from a trusted outlet / nursery, but you can also get hold of seeds from friends and prepare them for planting in advance:

  • disinfect rosemary seeds in a 2% solution of potassium permanganate for 15 minutes to prevent fungal diseases and infections.
  • Next, immerse the seeds in woven bags (napkin, multilayer gauze) for 1-2 days in a solution of wood ash (1 tablespoon of ash per 0.5 l of water; + 20-24 ° C) or a solution of liquid humic fertilizer PETER PEAT " Living force: for soaking seeds. As soon as the sprouts begin to hatch, remove all unsprouted specimens with disinfected tweezers. Do not allow the roots to germinate - the plants will slow down in development.
  • Perform a sparging operation - place rosemary seeds in a jar of water for 12 hours and dip the aquarium processor into it. Seeds are saturated with oxygen and moisture, after which they must be immediately planted in a planting container. Bubbling is an optional but desirable procedure for seeds older than 6-8 years, which significantly affects the growth and strength of seedlings.

Growing seedlings

Rosemary loves light loose soil of neutral acidity Fill the planting container with light, loose, moisture-absorbing soil of neutral acidity, at least 8 cm thick, options:

  • mix high, leaf soil, compost, sand and peat in a ratio of 2: 2:1:1:1;
  • , use the ready-to-use PETER PEAT Seedling Primer from the HOBBY line.

Sprinkle the soil with warm (+28°C) water, then make 0.3-0.5 cm indentations in the soil with the tip of a pencil, spacing 10 cm between rows, in a checkerboard pattern. Dip 2-3 seeds into each recess and carefully sprinkle with soil. Cover the container with rosemary seeds with transparent glass / film and keep it in a room with a temperature of + 18-22 ° C, preferably under a phytolamp (at least 12 hours a day, at a height of 90 cm from the container) - in 12-14 days the first shoots will appear. All this time, the soil with seeds must be sprayed with warm water from a spray bottle, without overflowing, i.e. the top layer of soil should be only slightly damp. Once a week, it is allowed to feed the seedlings with PETER PEAT liquid humic fertilizer "Living Force: Healthy Seedlings", it is also necessary to air rosemary seedlings 3-4 times a day for 20 minutes.

Seedling picking

After the appearance of 3-4 first leaves on rosemary sprouts, pick the young seedlings either into individual 7x10 cm peat pots (when they reach a height of 8-10 cm, transplant them to the final places of growth), filled with soil PETER PEAT Microparnik "HOBBY line, or directly into "adult" pots 35x40 cm. When picking, try not to damage the tender roots: take them out along with adjacent clods of soil and plant them in new containers. Temperature - not lower than + 24 ° С, phytolamp - 12-13 hours a day, otherwise rosemary will grow and develop poorly. 10 days after picking, feed the plants with liquid humic fertilizer PETER PEAT "Living Force: Healthy Seedlings", and after another 2 weeks - complex mineral fertilizer PETER PEAT "NPK 15-15-15" of the MINERAL line.

Care

  • Do not keep rosemary in a draft - the plant will actively shed its leaves.
  • Temperatures below + 12°С will already be uncomfortable for the plant: at home, be careful with airing and taking rosemary into the fresh air in spring / autumn to “breathe”.
  • Rosemary is quite drought-resistant, but does not tolerate overwatering very well. Watering is carried out every 4-5 days, when the topsoil dries out by 3-5 cm. Also, the plant really likes spraying with warm settled water 1-2 times a day.
  • After each watering, loosen the soil in pots 1-1.5 cm deep and remove possible weeds.
  • Top dressing of adult rosemary is carried out once every 4 weeks, and it is better to use complex fertilizers once a quarter, and liquid humic fertilizers once a month. Ideally, nitrogen fertilizers are suitable in spring, complex fertilizers in summer, and phosphate fertilizers in autumn.
  • Do not skimp on a phytolamp (12-14 hours/day): your apartment lighting will not be enough, and with its help rosemary grows 1.5-2 times faster. Lack of lighting will impair development, reduce the amount of essential oils, and, accordingly, the aroma of the plant.
  • To form a beautiful crown (in early March and after flowering) and rejuvenate the bush (every 7-8 years, “under the stump”), rosemary should be cut periodically.

Propagation by dividing the bush

The easiest way to propagate rosemary is by dividing the bush. In March, carefully remove the rosemary bush, previously spilled with warm water, along with a clod of earth from the pot. Secateurs, trying to disturb the lump as little as possible, separate the parts and immediately plant them in new pots.

Propagation by cuttings

Most commonly propagated by cuttings of annual shoots. The best time for harvesting them is September-October. Bark-covered and peeled bottom cuttings 10 cm long with 3-4 internodes immediately plant in a prepared container, deepening them by 3-4 cm at an angle of 45 °. For a week, it is a good idea to cover the rosemary cuttings with a transparent film / plastic bottle with small holes for ventilation. Rooting with this method will be 60-80%. With a feeding area of ​​10x10 cm per seedling and good care, standard future rosemary bushes are grown throughout the year.

But you can first dip them into glasses with a solution of liquid PETER PEAT humic fertilizer "Living force: for soaking seeds", while the place of residence should be illuminated, but without direct sunlight. It is important to maintain a temperature of + 22-24 ° C all the time, spray and water the plantings with warm settled water and once a week feed with liquid humic fertilizer PETER PEAT "Living Force: Healthy Seedlings". After 3 weeks, roots will appear, then rosemary cuttings can be transplanted into separate pots with nutrient soil PETER PEAT "Microparnik" of the HOBBY line. Carry out cuttings at the end of June.

Harvesting and storage

Since the highest concentration of essential oils in rosemary is observed during its flowering period, at this time prepare dry spices for the winter. It is advisable to cut only young shoots. The twigs can simply be tied together with string and hung to dry in a shady spot. Store dried seasoning in glass jars or canvas bags - this way it will retain its aroma and beneficial properties for 3 years.

Fresh rosemary leaves give a stronger and brighter aroma, and this spice does not lose its aroma during long cooking, it can be added at the beginning of cooking, and then removed before serving, however, calculating the dosage, otherwise the bitterness of rosemary can spoil the dish.

Diseases and pests

  • Mu pure dew – rosemary leaves develop a coating that is barely visible due to their color, they darken and crumble.
    Treatment: spray with cooled wormwood decoction (100 g of dry wormwood per 400 ml of boiled water, bring to a boil and simmer for 5 minutes) or strong tincture of garlic. In extreme cases, spray rosemary with special preparations - colloidal sulfur or copper sulfate. But after insecticides, rosemary leaves cannot be used, you need to wait for new ones.
  • Spider mites, whiteflies, aphids are harmful insects that undermine the health of rosemary.
    Treatment: spray with cooled wormwood decoction (100 g of dry wormwood per 400 ml of boiled water, bring to a boil and simmer for 5 minutes) or strong tincture of garlic. Or use insecticides - FAS, Aktara, Kinmiks, Strela, Intavir.

Attention! After treatment with insecticides and other chemicals, rosemary leaves cannot be used, you need to wait for new ones.

outdoor and indoor cultivation, propagation

The rosemary plant (Rosmarinus) is part of the Lamiaceae family. This genus is represented by evergreen shrubs and shrubs. Under natural conditions, this plant can be found on the territory of such European countries as Portugal, Italy, Spain, Greece, in the southern part of France and in the countries of the former Yugoslavia, and also in North Africa: Tunisia, Libya, Morocco, Algeria, and also in Turkey and in Cyprus.

From Latin, "rosemary" is translated as "sea freshness", this is due to the fact that the ancient Greeks associated rosemary with the sea Aphrodite, which appeared from the sea foam. However, the smell of this plant is not at all similar to the iodine marine aroma. It is more like a combination of the smell of camphor and pine, so the Greek name of the plant, which translates as "balsamic shrub", is closest to the truth. Previously, people believed that rosemary improves memory, in connection with this, in ancient Greece, students often put wreaths on their heads that were woven from rosemary branches. In culture, this plant has become popular due to its special aroma. This plant is included in the composition of the "bouquet garni" and the collection of Provence herbs, and it is also put in drinks, marinades, and vinegar is also insisted on rosemary. Such an evergreen shrub is distinguished by its thermophilicity, therefore it can be grown in open ground only in those regions where winters are warm. And in those countries where the climate is cool, rosemary is grown as a container and room culture.

Rosemary Features

Rosemary is a shrub that can grow from 0.5 to 2 meters in height. Its root system is very powerful and developed, it penetrates the soil to a depth of 3-4 meters. There is pubescence on the surface of grayish, obtusely four-sided young shoots. Perennial woody stems with peeling bark are painted in a dark gray shade. Sedentary linear leaf plates are leathery to the touch and have edges bent down. The leaves are about 0.4 cm wide, and up to 3.5 cm long, their front surface is glossy, and on the wrong side there is pubescence. Lush paniculate inflorescences consist of flowers of pale purple, dark purple or white. This plant is related to the following crops: hyssop, basil, lavender, mint, motherwort, thyme (thyme), oregano and lemon balm. The upper parts of annual shoots, along with foliage and flowers, are used fresh, adding to dishes of legumes, cabbage, eggplant and meat.

Planting rosemary seedlings

When to sow seedlings

Rosemary is propagated by seed, cuttings, dividing the bush and layering. In regions where winters are cold, this plant is recommended to be grown from seed through seedlings. Sowing seeds is carried out in the last days of February or the first - March.

Seeding features

Before sowing, the seed material is soaked in water for several hours. When the seeds swell, they are sown in moistened sand or vermiculite, and they need to be buried in the substrate by only 0.3–0.4 cm, and the container must be covered with a film on top. If you want seedlings to appear as soon as possible, the crops are constantly kept warm (25 to 30 degrees). Do not forget to systematically remove the shelter and moisten the substrate with a spray bottle so that it is constantly slightly damp. If everything is done correctly, then the first seedlings should appear after 6-8 weeks. Immediately after this, the shelter is removed, and the crops are moved to a well-lit place. Remember that the substrate in the container must be watered regularly, for this they use warm, well-settled water. After the height of the seedlings is 70–80 mm, they are planted in open ground.

Planting

The first step is to grow rosemary seedlings from seeds, how to do this is described in detail above. After the height of the seedlings is 70–80 mm, they dive into separate pots (it is better to take clay ones), which should reach 9–11 centimeters in diameter, there must be drainage holes at the bottom. The container should be filled with a substrate that is well permeable to air and water; to create it, a universal soil mixture is combined with vermiculite or sand. You can make a soil mixture from humus, sand, soddy and deciduous soil (2: 1: 2: 2). A small hole is made in the wet soil mixture, the depth of which should be equal to the height of the seedling root. Carefully remove the plant from the container, taking it along with an earthen clod, and plant it in a pot in a prepared hole. Lightly tamp the substrate around the plant.

It is recommended to place the planted bush on a south-facing window. In order for the crown of rosemary to be beautiful, and not one-sided, regularly once every 7 days the container with the plant is rotated around its axis by 180 degrees. In the spring and summer, it is recommended to move the bush to fresh air (terrace, garden or balcony) if possible. With the onset of autumn, after the air temperature begins to drop to minus 1 degree, the plant is transferred to the house. It is undesirable to ventilate the room where rosemary is located, as cold air from the window can harm it. However, if there is no air circulation in the room, then mold may appear on the bush. To avoid this, a fan should operate in the room daily for 3-4 hours. In winter, the air temperature in the room should be below 16 degrees, and the humidity level at this time the bush needs to be low.

Pests

When grown indoors, aphids and arachnids can settle on the plant. If you notice pests on the bush, then treat with a solution of an acaricidal or insecticidal agent. At the same time, remember that several treatments may be required to completely destroy pests.

Watering

Make sure that the soil mixture in the pot with the plant is constantly slightly moist (not soggy). You can understand that the shrub lacks moisture by the lower foliage: it turns yellow. If there is too much moisture in the soil mixture, then the foliage begins to fly around the bush.

It is recommended to moisten the substrate in a pot with a watering can with a long and narrow spout, because water should not fall on the surface of the leaves, as this can cause mold. Before watering, the water should stand for at least a day, and its temperature should be close to room temperature.

Fertilizer

During the growing season from March to September, the plant needs to be fed with mineral fertilizers, which must include calcium. Top dressing is carried out regularly twice a month. In winter, the plant is not fed at all, or it is done much less frequently (once every 4–6 weeks).

Growing rosemary outdoors

You can also grow rosemary outdoors. To do this, choose a well-lit place that has reliable protection from gusts of wind. The soil needs light, loose, well-permeable water and air, and it is desirable that it be limed.

Seedlings are planted in open ground from the middle to the end of May after the warm weather sets in, by which time the seedlings should reach a height of 70 to 80 mm. If you plan to grow large bushes, then when planting seedlings, a distance of half a meter is kept between them. And if you do not plan this, then it is enough to maintain a distance of 10 centimeters between the plants. Planted bushes need to be watered.

Care instructions

Growing rosemary in your garden is not as difficult as it may seem. You need to take care of it in almost the same way as for other garden crops, or rather, it should be systematically watered, fed, weeded, cut, and do not forget to loosen the soil surface in a timely manner.

After 7 days after planting, the tops of the stems should be pinched off near the bushes, in this case they will grow more magnificent and spectacular. Remember that the first flowering of such a plant can be seen no earlier than the second year after planting in open ground.

Pruning

Upright rosemary bushes, starting from the age of two, are cut at a height of 3-4 internodes on last year's growth, and this is done in April. Prostrate rosemary does not need pruning.

Pruning in order to rejuvenate the shrub is carried out once every 7 years, for this all the stems are cut at the level of the soil surface. In the spring, formative pruning is also carried out. You can form a plant in the form of a cube, a ball or a miniature tree (for example, in the form of a cypress). Rosemary broom-shaped bonsai is very popular among gardeners.

Wintering

This shrub is heat-loving, so in mid-latitudes it can die in winter. In order to keep the plant until spring, it is dug up and planted in a container, which is transferred to a well-lit and cool (not higher than 16 degrees) room. If it is not possible to dig up rosemary, then it is cut off at the level of the surface of the site and covered with a layer of dry foliage or sawdust, then a tent is made around the plant from spruce branches.

Watering

Rosemary is distinguished by its drought tolerance, but it still needs timely and proper watering. If the plant feels a lack of moisture, then because of this, its lower leaf plates will begin to turn yellow. And due to the regular stagnation of fluid in the soil, part of the root system of the shrub dies off, and its foliage is also observed flying around.

Watering should be moderate. Pour water gently under the root, because if its droplets fall on the foliage, then mold development may begin because of this.

Fertilizer

In the springtime, it is recommended to apply a nitrogen-containing fertilizer to the soil on the site, this will be a great start for the growth of rosemary. And then, throughout the entire growing season, a complex mineral fertilizer is systematically applied to the soil once every 30 days. In autumn, fertilizers are used for top dressing, which do not contain nitrogen, but it should contain a lot of phosphorus.

What to grow on the plot after rosemary?

This plant is a perennial, but if you decide to remove it from the site, then you should dig up the bush and clear the soil of plant debris. Digging the soil, while adding compost or humus to it. Onions, carrots and garlic will grow well in such a site.

Propagation methods

How to grow rosemary from seeds is detailed above. However, this is not the only way to propagate such a shrub. So, it can also be propagated by layering, cuttings and dividing the bush.

Cuttings

Cuttings are taken in September-October, for this, annual stems are used. The length of the cuttings should be from 8 to 10 centimeters, and they should also have 3 or 4 internodes. From the bottom, tear off all the leaf plates and treat the lower cut with a drug that stimulates root growth. Planting cuttings for rooting is carried out in a container filled with a loose and light substrate, well permeable to water and air, and pre-sterilized (for example, you can take a mixture of vermiculite and peat). Store the cuttings in a warm place out of direct sunlight.

Keep the soil mixture in the container slightly moist at all times, and the cuttings themselves must be moistened with water from a spray bottle every day. When new leaf blades grow on the cuttings, they are transplanted into individual pots in diameter reaching from 70 to 90 mm. 7 days after transplantation, the tops of the cuttings are pinched, thanks to which they will grow more magnificent and spectacular.

Cuttings

To propagate rosemary by cuttings, you need to choose shoots from the bush that grow very close to the soil surface. The shoots are bent to the ground, then they are fixed and dug in with soil so that the top of the stem remains above the surface. Give the layerings regular watering so that the ground around them is always slightly moist. After the tip begins to grow, the layer is cut off from the parent plant and planted in open ground or a pot.

Dividing the bush

Propagation of rosemary by dividing the bush is most often resorted to when growing it at home. After the bush is pulled out of the container, its root is divided into parts. Please note that each division must have stems and roots. Sprinkle the cuts with charcoal powder and plant the delenki in individual pots.

Diseases and pests

When grown outdoors, rosemary is very resistant to pests and diseases. However, a bush growing at home is sometimes affected by downy mildew in winter, and whiteflies and aphids can also settle on it. To get rid of pests, gently lather the bush, and then rinse it under a warm shower. Moreover, the surface of the substrate in the container must be covered with a film so that soapy water does not get into it. To prevent downy mildew, do not allow excessive humidity levels in the room and potting mix. And also experts advise using a fan in winter to create air circulation in the room.
