Consider some simple rules for growing Coleus. in the garden.
Where to plant coleus
I was able to get rid of ARTHROSIS AND OSTEOCHONDROSIS PER MONTH! Operations are not needed. Read more here.
If you plan to plant Coleus in open ground, you should choose the right place for its cultivation. The flower prefers sunlight, its leaves best show their color under bright rays. But there are some nuances here:
- If the plant has white or red leaves, then it is planted under direct sunlight.
- Varieties with green leaves and its shades are not so fond of bright light. While the sun is very active, the plant will need to be shaded. Or you can immediately plant green flowers in a dark place. If this is not done, the leaves will burn.
Interesting! Although initially the plant had only one name - Coleus, in everyday life you can often hear another name - nettle. Perhaps this is because some of its foliage is similar to nettle.
Soil selection is also one of the important points for planting Coleus. In principle, the composition itself can be any, but the presence of nitrogen and nutrients in the soil is obligatory. This contributes to the full growth and development of beautiful, bright leaves with a more pronounced stencil pattern.
That the seeds germinated, the most nutritious will be the mixture:
- 4 portions of black soil,
- 2 portions of pine needles,
- 2 servings of cow dung
- 1 portion of sand.
Ground for the preparation of the mixture should be well warmed and sieved. In order for the plant to begin for sure, it is necessary to plant the seedlings in a separate container, and after germination, transplant into the ground in the garden.
Growing from seed
Coleus can breed and seedsand seedlings. To determine the appropriate option, you must familiarize yourself with all and decide which method is best to use.
For example, using seeds, seedlings will have to wait longer. When planting seedlings can quickly get a full-fledged ornamental plant. But often the price of seedlings is too high. And you can buy seeds of various colors, English and Dutch species, which are sown at the end of March.
If seeds are sown at another time, it may be necessary to additionally arrange artificial lighting for seedlings.
- You should take the fertile land and thoroughly heat it.
- Seeds are laid out on the ground surface, it is better to use a flat box.
- Seedlings sprayed with a spray bottle and sprinkled with a thin layer of sand.
- Capacity covered with glass, transferred to a dark warm place.
- The ground should always be slightly wet.
Tip! It is better to choose seeds in special stores to be sure of their quality.
- Shoots will appear in a week.
- When the first shoots appear, the glass is removed, and the container is transferred to a bright place, preferably to the east or west window.
- The best temperature is 17-19 degrees, and direct sunlight should not be allowed.
Planting coleus seeds is a simple but effective method for growing an ornamental plant. If you have time, then it is better to resort to this method. Moreover, it is more economical.

The seedlings are planted in open ground when the soil warms well. And if the seedlings are grown independently on the windowsill, then you just need to plant it on a flower bed.
If you plan to buy seedlings, then first choose the variety that will be grown.
The first of all varieties, which began to grow in the garden - is "Blume". From him a lot of popular hybrids:
To choose the right seedlings, you should pay attention to the color of the leaves, the stem and the elasticity of the plant. If the shoots are sluggish and dried, then it is better not to take them.
In open ground, seedlings are planted in early June, when the earth is already completely warmed up and there will be no more night frosts.
Having dug holes of suitable size, a nutrient substrate is placed there and seedlings are planted. It is necessary to measure the distance between the bushes.
After planting, the plant needs moderate watering. Caring for Coleus does not require much effort, especially if you plant annual plants. Perennial need to dig out from the garden and store them until spring in pots.
How to water
In the warm season, the nettles that grow in the garden should be watered moderately. It is better to use separated or rain water. When the air temperature is very high, the plant is additionally sprayed, and it is monitored to ensure that the topsoil does not dry out.
In winter, watering should be reduced, but the soil should not dry out. If the moisture is not enough, the plant will start to wither and lose elasticity. If the temperature is less than +14 degrees, water will be rarely needed.
How to feed coleus
Both annual and perennial types of stinging must necessarily be fed:
- For the first time complex fertilizers are applied 14 days after picking the seedlings. Feeding up young plants, it is better to reduce the dose, which is indicated on the package, approximately 3-4 times.
- When the active growth of coleus begins, you should feed once every 7 days. To do this, you can take and mineral fertilizers, which are used specifically for ornamental plants, and potassium compounds (0.5 g per 1 liter of water).
- In winter, you can feed once every 30 days, but fertilizers should be diluted 2 times from the indicated dose.
Pruning and shaping
Both indoor and garden coleus should be trimmed to give it a certain shape. Garden plants practically do not need pruning, unlike indoor. But Coleus should be cleaned from the leaves that have withered, as well as dried flowers. Cut the plants before each new season, it will help to save the plant for another few years. Pruned shoots at a height of about 5 cm, which can be used to germinate cuttings.
How to grow coleus
Reproduction of Coleus occurs in two ways:
Planting cuttings is the ability to quickly get large and healthy plants.
- Cut cuttings in late winter or early spring.
- They are planted in the ground or put in the water.
- Roots appear within 1-2 weeks.
- When the roots get stronger, the nettle is planted in peat pots.
- In order for the plant to grow, you should pinch the tops.
- In the ground at the dacha plant sprouts only when the temperature during the day will be within +16 degrees.
Seeds are sown in boxes with nutrient capacity and sprinkled with sand, as described above.
- With proper care and temperature conditions (approximately +20 ° C), shoots can appear from 7-20 days.
- Planted sprouts in peat pots, in a mixture of leafy earth, sand and sod for one piece.
- Water them regularly, until planting in open ground.
Important! It is worth remembering that Coleus is growing quite rapidly.
Those plants that are sown with seeds, turn into large and strongly branched plants with large leaves within 90 days.
If cuttings were planted, the process is even faster. In order for the bush to grow not only in height, but also in width, you just need to pinch the tops of the shoots.
Unpretentiousness and undemanding care, makes Coleus a good decorative inhabitant of many flowerbeds and garden plots. Flower arrangements that are created in the garden with the help of Coleus will please the eye of gardeners.

The separation takes place in the form of growth. In nature, there are many varieties of this shrub. Among gardeners, the following have gained popularity:
- Hybrid. The plant reaches up to 80 centimeters in height. Stems have a fine down. The leaves are oval-shaped. Good for growing in the garden.
- Blum. Java is considered the birthplace of this species. Among the varieties there are dwarf representatives, as well as high. Tall shrubs reach up to 70 centimeters in height. Leaves have a traditional form. The shape of the sheet resembles nettle. The color of the leaves is represented by a wide range of colors. The most common varieties of this species: Saber, Firebird, Golden Bedder.
- Renelta. Sri Lanka is considered the birthplace of shrubs. From this kind of wonderful hybrid varieties. Renelta used in decorative design.
All varieties are different from each other, however, there are common external similarities for most species:
- The shrub has almost transparent stems,
- The leaves have a velvety pile,
- Coleus is grown for its leafy beauty. Nevertheless, the shrub has flowers. The flowers of this plant are very small and inconspicuous,
- Leaves can be a variety of colors and shapes. The most common red, scarlet, orange and green leaves. The leaves look like nettle leaves,
- This is a pretty unpretentious plant.
Reproduction occurs in two ways:
- With the help of cuttings
- Planting seeds.
Among these methods there is no preferred. In flower shops for sale is already ready for planting seedlings. Coleus feels good both at home and in the garden. In this plant, flowers are not valuable. In turn, the leaves have a pleasant aroma. Transplantation in the open ground is carried out with the arrival of spring. This is an unpretentious plant, but does not tolerate drafts. Landing should be carried out on a well-lit area of land.
Cultivation with seeds
Coleus is amenable to growing with seeds. Not only the professional, but also the beginner will cope with this business. This method allows you to grow seedlings in a pot. If there is a need seedlings are transplanted into the garden.
For planting coleus in the garden will need:
- Choose a suitable landing time. This is a thermophilic plant, so sowing it is necessary after warming. Should focus on the climatic conditions of their area. Before planting, it is advisable to make sure that the onset of sudden frosts will not occur again.
- You should choose a quality planting material. The success of the event directly depends on the planting material. It is advisable to buy seeds in specialized flower shops. Attention should be paid to the shelf life of seeds. The expiration date is indicated on the seed package.
- Choose a well-lit area. It is desirable that the site was protected from the wind.
- The wells for planting seeds should be at a short distance from each other.
- It is advisable to treat the seeds with special dressings.
- Seeds are laid out in the hole, and then watered. Water for irrigation should be at room temperature.
- It is advisable to cover the crops with polyethylene. Such a shelter will protect the seed from sudden night cold.
This method is intended for sowing annual crops. Shrub will have to dig to save it for next year. Digging occurs to the onset of cold weather. The plant is placed in a pot with the earth and stored in a dwelling. Shrub requires lighting. Therefore, it should provide the backlight with a lamp.
Growing with cuttings
Cutting is the most convenient way to grow Coleus.. This procedure allows you not only to plant, but also to rejuvenate the plant. If the plant loses its beautiful appearance, then grafting saves this situation. You just need to nip off the sprout and then put it into the water. The coleus stump quickly takes root in the water. In this position, the stalk is able to stay all winter. Strengthened cuttings transplanted into the ground.
The cutting quickly take root in the ground. Planting is carried out in the land treated with fertilizer. Top dressing allows you to accelerate the growth of the cutting, as well as strengthen the root system. Treated with top dressing, the root system acquires protection from diseases. The cutting practically does not require any maintenance. It is necessary to plant it when the frost has passed. Planted stalk begins to grow. It should pinch to get a beautiful shrub. Pinching occurs in a situation where the stalk becomes a dried stem. From the site of pinching begin to move the branches.
This plant requires care. However, difficulties with care will not arise. For the cultivation of healthy shrubs need to adhere to the following points:
- Selection of the correct lighting. Coleus is a light-loving plant. Nevertheless, plant it in direct sunlight is not worth it. You should choose a lighted plot of land, but with a light shadow. Coleus will not die from exposure to the sun, but the leaves will not be so bright.
- Shrub does not like drought. But overmoistening is desirable to avoid. It is advisable to conduct evening spraying. Drops form a kind of lens. These water lenses focus the sun's rays, after which burns appear on the leaves.
- Coleus tolerates heat, but does not tolerate winds. It is necessary to protect the bush from a sharp change in temperature. This applies to home plants. It is advisable to place a pot with a flower on the east side of the house.
- Suitable for planting any soil. It grows well in almost any suitable land.
- The plant quietly dispenses with fertilizer. But the shrub well perceived in the diet supplements. For fertilizing any mineral fertilizers are suitable. When applying fertilizer should use the instructions.
- Coleus loves loose soil. Loosened soil allows the root system to saturate the air and moisture.
- Dry leaflets should be removed.
Diseases and harmful insects
Coleus in open ground exposed to diseases and pests. There are the following difficulties with this plant:
- There is a risk of stalk being exposed. The stem is exposed in the lower sections of the bush. The reason for this is the lack of timely pinching.
- In direct sunlight, the plant loses its leaf color. The leaves fade gradually, and then become pale. In such a situation, it is desirable to transplant the shrub in a more shaded place.
- Insufficient water leads to leaf fall.
- The stems are drawn from a lack of sunlight.
There is also the risk of attacking insects. Coleus is attacked by aphids, spider mites and whiteflies. Disposal of these insects occurs with the use of insecticides. For the treatment of plants from harmful insects used Karbofos, Spark and copper sulfate. After spraying, it is advisable to cover the shrub with polyethylene.
Adding an article to a new collection
Coleus is known for its incredible shades of leaves, fancy patterns and contrasting border. In order for the flower garden to play with bright colors, the plant needs to be properly planted and proper care provided.
Large-leaved forms (for example, Coleus Blume, or Blum) are most often planted in the garden, as they quickly form fluffy bushes. In addition, this plant can be propagated by cutting over the entire season and creating bright flowerbeds with it.
Landing Coleus in the ground
Coleus is planted in the ground in spring (as soon as it gets warmer) or in summer. To do this, choose a well-lit and protected from the wind place, dig holes there at a short distance from each other so that the bushes do not interfere with each other, fill them with fertile substrate and plant plants there.After that, moderately watered and slightly shaved, so that the bright spring sun did not burn the leaves.
The brighter the pattern on the leaves of the plant, the more sun it needs, because in the shade the color fades and the stems are drawn out. The optimum air temperature for the normal development of the young Coleus is above 10 ° C, and the adult bushes in the fall are able to withstand short-term cold spells of up to 7 ° C.
Coleus seedlings can be grown from green cuttings or seeds.
Coleus Blume is watered as the topsoil dries. Ideally, the soil should always be slightly wet, because during drought the leaves of the plant wilted and lose their decorative effect.
In the garden, watering can be made from a hose: the sheet plate will not be affected if water gets on it. However, it is important to prevent fluid from stagnating. Otherwise, the roots of the plant may rot.
During the growing season, Coleus is fed once a week with mineral fertilizers for decorative foliage plants, but it is important that the dressing contains the minimum amount of nitrogen. The fact is that with an excess of this element the leaves become pale. In winter, fertilizers are not applied at all, but if coleus overwinters with artificial and insufficiently bright light, then it can be continued to be fed once a month.
Coleus shrub formation
To young plants better branched, they have 1-2 cm pinch tops. When the flower arrows begin to appear, they are removed for the first time so that the bush grows its roots and leaves, and does not spend all its power on flowering.
Peduncles leave only fully formed bushes
As required throughout the growing season Coleus pruned. After pruning, the bushes grow better in breadth and form a lush carpet on the flowerbed.
Fight against diseases and pests
Most often, Coleus is attacked by a spider mite, aphid and whitefly. They are fought with insecticides. It is advisable to use biological products: Actophyte, Bitoxibacillin, etc.
Coleus Blume - the plant is quite resistant, but with the wrong care can get sick. So, when the gulf plants grow rot, the lack of pruning leads to the stalk of the stem, and the lack of lighting affects the state of the leaves: they fade, turn yellow and fall off. To prevent this, carefully observe the rules of growing Coleus.
Coleus care in winter
Often, Coleus is grown in the open ground as an annual plant and is removed from a flower garden to a balcony, loggia, winter garden or house on a well-lit window sill located on the south or south-west in late autumn. Old bushes, as a rule, do not replant. From them in the first half of September, cuttings are cut and rooted at home in peat or water.
Coleus cuttings are usually rooted in 0.5 l containers
It is important that coleus get enough light in winter, so in dark rooms you may need artificial illumination with phytolamp. The air temperature should not fall below 8 ° C, reduce watering and protect plants from drafts. Then during the winter they will retain their decorative effect.
In late February - early March, coleus rejuvenate: in adult bushes, old leaves are removed, and shoots are pruned. This stimulates the development of new stems at the base of the plant.
When warm weather sets in in the spring (the air temperature does not drop below 10 ° C), coleus are resettled to the ground again. With this care, colorful bushes "netting" will be bright and healthy all year round.
Coleus: types, varieties and description
The above-ground part of the inhabitants of the tropics is represented by silvery shoots, which are covered oppositely arranged, toothed leaf plates resembling nettle, for which the people received the name culture "nettle". Leaf color is varied - green, yellow, burgundy and red. Flowers that do not represent special value, form racemes of blue or lilac color.
Despite the fact that the genus in the wild has more than 150 species, in culture it is represented by only a few species.
The open shrub is a semi-shrub up to 80 cm high with lignified base from tropical zones of Southeast Asia, which became the basis for the work of breeders in breeding many varieties.
The most popular representatives of the species:
- Coleus "Black Dragon" - a variety that stands out brownish-purple foliage with corrugated edges and pronounced streaks of red.
- Coleus "Wizard" is a variety series deserving attention due to the motley coloring of leaves framed by borders of various sizes and shades.
The species gained the greatest popularity in indoor floriculture, although it is sometimes possible to meet it in the garden. Small plant capable of reaching a height of one meter. The color of the oval-shaped elongated leaves with serrated edges may vary depending on the amount of light produced. In the shade, the leaves of the representative of the tropical Laura are green, but if the flower grows in sunny areas, the leaf plates become burgundy.
Ampel form is grown in hanging pots, used for decoration of balconies, terraces and courtyards. The species is distinguished by heart-shaped petioles, which are decorated at the edges with multi-colored streaks, giving the appearance of special charm.
The most famous species and varieties of plants
The coleus are popularly called the croton of the poor. They themselves come from hot Africa and the rainforests of Asia. They are characterized by ribbed stems, lignified at the very base, as well as very attractive heart-shaped, toothed, pubescent leaves, which are a bit like nettles. The color of the foliage of these plants is simply enchanting, it can combine shades of maroon, green, bright red and even yellow tones. Purple or blue flowers of coleus are collected in small spike-shaped inflorescences. However, the cultivation of this plant is made solely because of the stunning decorative beauty of its leaves.
Fantastic Coleus, annual and perennial, today has about 150 different species.
For example, polyhybrid varieties and types have earned enormous popularity in indoor floriculture. One of their parents was Coleus Blume. The height of the representatives of this species is about 1 m, and its leaves have an oval shape and serrate edges. The shade of the foliage may vary, depending on whether they are in the shade or in the sun.

From lack of moisture, as well as from waterlogging, the leaves can just fall off, and poor lighting will affect the color of the foliage.
Spider mites, whiteflies and aphids can affect Coleus. In the fight against aphids use processing soapy water. Ticks are destroyed with drugs such as Oberon or Akarin, and whitefly with Aktara.
Use in landscape design and combination with other plants
Because of the rich and rich colors, coleus are best combined with monochromatic plants with openwork greens. For example, coleus perfectly harmonize with cineraria, sage, which will create a magnificent background for them. In addition, gypsophila, all kinds of lilies, daylilies, etc. will become wonderful neighbors for them.
Having planted a Coleus of several varieties on a flowerbed, you will get a fantastic composition, very effective and colorful. This plant is best suited for creating ceremonial flower beds with patterns that often adorn urban parks and alleys.
In short, this is a real find for modern landscape design. You can see the use of Coleus in various design options for the plots in the photo
Coleus, a thermophilic plant. For him, the temperature below 12 0 C is already destructive. There is not enough time for seedlings and development of the bush in favorable conditions. Therefore, in the middle lane, coleus is grown in the open field by planting and caring through seedlings. Seeds can be harvested on their own, but they will not pass on the coloring of the parent bush. It is better to use varietal material from specialized farms. Grown from seeds, coleus well take root in open ground.
Young plants quickly grow foliage, and the gardener's task is to provide:
- lighted place with shading and protection from the wind,
- watering regular and abundant,
- weekly fertilizer, in the spring with a predominance of nitrogen, later, ash extracts for bright leaf color,
- bushes as they grow shave, giving the desired shape.
With proper care, coleus in the garden will look like in the photo.
How to grow seedlings Coleus
Coleus can be propagated by seed and cutting. If you get young plants from seed, the seedlings will turn out different leaf color. To obtain the same bushes reproduction is used cuttings.
Sowing seeds carried out in March or April, depending on the period of the onset of summer in the region. The seeds are very small, they are laid out on the surface of the substrate and lightly sprinkled with sand. The container is covered with glass, kept warm, constantly moistening the surface. The sprouts that appeared in two weeks will interfere in a cool, bright place so that they do not stretch out.
The time when it is necessary to dive the coleus into separate cups is determined by the condition of the young seedlings. If they stretch, interfering with each other, it means that the time of transplantation has come. Therefore, it is important to decompose the seeds of Coleus as rarely as possible so that at the school stage you get a strong plant with developed roots.
Coleus pick will be easy. The survival rate of seedlings is good, grow quickly. After the trunks have grown to 10 cm, they begin to pinch, forming a bush. If the summer is delayed, you can make another transfer of the plant into a larger glass.
To ensure planting in the open field and caring for Coleus from seedlings, you need to dig holes, fill them with fertile soil, water and cross the bushes, injuring the roots as little as possible. Novocadki cover for several days for better survival. Watering plants need soft and warm water.
In order to highlight the beauty of the carved leaves and the bright color of Coleus, you need to plant it against the background of monochrome plants. Created by them drawstring will be an excellent protection from the wind.
In autumn, annual plants should be dug up and added to heat for future grafting. Bush perezimuet perfectly at home on the window, delighting with its bright leaves. But caring for coleus is associated with pruning. Otherwise the bush will simply stretch and lose its decorative effect.
From February to May, all cut-off upper shoots give roots in water or in wet sand for ten days. Then they are seated in cups, they provide proper care and receive young bushes for spring gardening of balconies and gardens.
Cuttings of seedlings completely repeats the colors of the mother bush.
Coleus care at home
At home, the plant does not need special attention. The plant should be planted in a deep spacious pot. Fertile land and good drainage will create conditions for the development of the root system. The plant is wetter, but from stagnant water the leaves will fly, and the root will rot.
Bright window, but without direct sunlight. Summer spraying on the leaves with warm soft water is essential in the care of Coleus, as factors of good farming. The flower loves fresh air and in the summer will decorate a balcony or a veranda with a bright spot.
Peak decorative Coleus falls on the age of 5 months from sowing seeds. Small-leaved varieties grow faster and cover the soil better. The higher the air temperature, the more often watering the plants.
Water for irrigation from the water supply must not only be separated, but also boiled, so that no salt or chlorine compounds are left. In the summer, for a bright color, the plant needs trace elements in the feed and nitrogen for rapid growth at the very beginning of development. In winter, watering is reduced, but the land is not dried. It is enough to carry out top dressing once a month. It is best to cut shortly regrown branches in order to make the ornamental bush in early spring. The plant will rejuvenate, there will be a material for grafting. Proper care for Coleus at home will create a bush worthy of a photo on the cover of a magazine.
Plant Diseases and Pests
Coleus care is considered an unpretentious plant, but some rules must be followed. From improper care, the plant can be weakened, lose its decorative appearance, pests will settle on it. More often at the same time houseplants suffer.
The main and frequent reasons can be:
- rotted stem down, it can happen with stagnant moisture, soured soil,
- the leaves begin to dry out from the tips - insufficient watering, dry air in the room, the plant is not sprayed regularly,
- the leaves on the nettle began to fall off - drafts and cold plant,
- spots on the leaves - sunburn,
- leaves dim - not enough light or not fed for a long time,
- flower growth has slowed down - there is not enough nutrition in the soil.
All this will lead further to the colonization of a weakened bush. They will show their presence by deformation, discoloration and drying leaves.
For seedlings seeding is carried out at the end of March according to the following scheme:
- The flat container is filled with the prepared substrate.
- Seeds are distributed over the surface of the ground, slightly pressed down and moistened with the help of a spray bottle.
- The container is covered with glass and moved to a shaded, warm place where the substrate is kept in a slightly moistened state.
- After emergence of shoots glass is removed.
- The box moves to a window with diffused light, where the temperature value varies between 17-19 ° C.
- When seedlings form the first pair of true leaves, they are swooped into special cassettes for the development of the root system.
- When two pairs of true leaves are formed, seedlings are planted in half-liter cups, where they are pinched for better branching.
After the onset of stable heat, when the threat of recurrent frosts has passed, you can start planting seedlings in open ground:
- A solar site is selected that is protected from the winds and slightly shaded during the period of solar activity.
- The holes are dug out with the size corresponding to the root system of the seedlings, with a small distance from each other.
- Each well is poured over the peat or compost to improve aeration and fertility.
- Then the bushes roll over from the cups and sprinkle with the extracted soil.
- The soil is slightly compacted and watered.
Caring for coleus in the open field
The flower has won the love of flower growers not only for decorative foliage, but also for undemanding care. To grow a healthy, lush plant will require a short list of simple procedures.
For the full development and preservation of decorative exotic flower in need of abundant watering, in which between new portions of water the earth should not dry out completely. Humidification should be carried out with separated water at room temperature, for which a barrel is well suited, where tap water will be collected, and then warmed up during the day.
Attention! При поливе необходимо руководствоваться чувством меры, поскольку переизбыток либо постоянная нехватка влаги может стать причиной сброса культурой декоративной листвы, за которую колеус и ценится.
Периодически приствольный круг под кустом необходимо рыхлить, чтобы не допускать образования непроницаемой корки. Weed control should be fought as necessary. As a rule, removing the weeds when loosening, to spend time separately for such a procedure is not required.
How to feed the plant?
In order for the plant to increase its green mass intensively, it should be fed weekly with liquid nitrogen-containing fertilizers during the growth period. High nitrogen concentrations will also contribute to the onset of the onset of the flowering phase.
To stimulate branching and get a lush bush with motley foliage that will maintain decorativeness throughout the season, Coleus cuts and pinches:
- The first pinching is carried out in the seedling phase to give the flower a bushy shape.
- During the summer period, Coleus is cut three times, which allows you to form a dense and well-groomed crown.
- When the flowers appear, the flower stalks should be removed immediately so that the plant does not spend any force on flowering to the detriment of the beauty of the leaves.
If you want a grower, he can save the flower life, but it will require:
- dig a bush out of the garden
- transplant the plant in a pot
- placed in a room with a temperature range of 8-15 ° C,
- reduce watering and fertilizing.
After the ground warms up sufficiently and the risk of frost disappears, the flower can be planted back into the garden or on a flowerbed.
In addition to the seed method of reproduction, which was described above, there is a vegetative method of breeding using cuttings when:
- From apical shoots that are cut when sheared, cuttings 10 cm long are harvested.
- Leaf plates are removed from the bottom of the resulting cutting.
- The resulting planting material is embedded in a special soil mixture of equal parts of sand and peat.
- Landing covered with plastic bottles.
- After 10-14 days, the formation of roots.
- New plants are planted on their designated places.
Thus, the garden can be decorated not only with flowering plants. Decorative Coleus with spectacular leaves of variegated colors, not requiring special care, will be a great addition to any landscape compositions.
