Coleus: plant description
Coleus belongs to the group of evergreen shrub and herbaceous annual plants with opposite foliage on the petioles. Perhaps it is the leaves that act as the most conspicuous part of the plant, featuring different colors and original patterns.
Coleus flowers are collected in the apical spike-shaped inflorescences, which are particularly well seen in single plantings in a flower bed.
In nature, there is a fairly large number of the most diverse species of this plant (both annual and perennial), but Coleus, growing in the garden, has its own characteristics. It reaches 80 cm in height, has a carved powerful stem, which begins to harden within 6-8 months. The leaves of the plant are presented in a variety of color variations, and their shape is often different. In some species, there is a well-marked multicolored edging.
When flowering, Coleus resembles sage, as it has nondescript blue flowers.
Unlike other types of tropical plants, any varieties of coleus are characterized by low demanding in terms of care, however, in order to grow a really beautiful plant, it is still necessary to follow some rules.Choosing a landing site
If you are going to get a Coleus at your summer cottage, the first thing to do is to choose the right place for it to land. This plant prefers a well-lit area, where under the influence of sunlight the color of the leaves of the flower will become as bright as possible.
However, here it is necessary to remember some rules. For example, varieties with red or white leaves are well tolerated by the direct rays of the sun, while varieties with green leaves (of any shade) react much better to bright light.
Because of this, during periods of increased solar activity, they need to be shaded, although it will be more practical to perform landing in partial shade immediately. If this is not done, there will be burns on the leaves, and the flower will lose all appeal. 
Soil requirements
In addition to the illumination of the selected area, the composition of the soil plays an important role in planting Coleus. By and large, the soil can be completely different, the main thing is that it contains a large amount of nutrients and nitrogen. The more of this element in the ground and feeding, the greener the leaves of the plant and less stencilled pattern.
A mixture of chernozem, pine needles, cow dung and sand in a ratio of 4: 2: 2: 1 is well suited for seed germination, and the earth should be sifted and well warmed. It is better to sow the seedlings in separate containers and only after germination the plants should be transferred to the open ground.
How to plant coleus
Having understood what a Coleus is, and having prepared a place for its landing, you can proceed directly to the process itself. Plants are planted more often in open ground, although in some cases gardeners use the seed method.
How to grow coleus from seed
Coleus reproduces well both by seed and by using seedlings., but before you put a nettle, it is worth weighing the pros and cons of each of the options. For example, it is not a secret that in the first case of sprouting you will have to wait a little longer, while from the seedlings you will quickly get a full-fledged ornamental plant. However, the seed method is much cheaper, since the price of seedlings is often very high.
On sale you will find excellent Dutch and English varieties that should be sown at the end of March.Sometimes the sowing of seeds is carried out at other times of the year, but in this case, it is quite likely that it will be necessary to arrange additional shoots for the seedlings.
The soil for the plant must be fertile and well warmed, so for breeding Coleus by seed it is necessary to use a flat box, spreading the seeds evenly on the surface of the soil. Seedlings are sprayed from a spray bottle and lightly sprinkled with a thin layer of sand.
After that, cover the container with glass and place in a warm and gloomy place, keeping the ground in a slightly damp state.
Planting Coleus seeds fully justifies itself, so if you are in no hurry and want to save a little, it is better to give preference to this method of planting.
Selection and planting seedlings
The planting of Coleus seedlings in open ground is carried out after the end of the cold weather, as soon as the earth warms up well. If you grow your own seedlings on your window sill, then all that is required is to simply transplant it in a flowerbed or garden.
However, if you want to buy ready-made seedlings, then first you need to decide on the variety. The cultivator of all cultivated Coleus species is considered to be the Blume variety, which also became the ancestor of the well-known hybrids of this plant (Rainbow series, Fantasia group, Dark Chocolate and Black Dragon varieties).
When choosing seedlings of this type, you should pay attention to the color of the leaves (usually they are rich pink with a green frame around the edges), the thickness of the stem and the elasticity of the shoots. Sluggish, dried or yellowish leaves with thin legs should be avoided.
Transplantation of seedlings in open ground can be carried out from the beginning of June, as soon as the earth warms up and the night frosts recede. To do this, keeping a certain distance, dig holes in the desired location of the desired size, add a fertile substrate to them, and land a Coleus. After that, all plants are watered moderately with water.
In general, in terms of care, Coleus can be called an undemanding plant, and during reproduction in any way, the growing process will not take much energy from you, especially if you are going to grow it as an annual flower. As for perennials, then they are dug out for the winter from their habitual place of growth and kept in pots until spring.
Features care for coleus in the open field
As in the home, and when growing Coleus in the open field, you must follow some rules for watering, feeding and trimming plants.
How to water the plant
From spring to mid-autumn, nettles growing in the garden and on a bed are watered abundantly with soft settled water (rainwater can be used), and on hot days they are additionally sprayed (make sure that the topsoil is always wet).
In winter, the frequency of irrigation should be reduced, while avoiding the drying of earthen coma. The lack of the right amount of moisture causes the plant to wilt, in particular, the leaves lose their elasticity. With temperature indices of + 14 ... +16 ° C, watering is rarely required, and a "dented" plant will tell you about the lack of moisture in the soil.
Coleus feeding rules
Any kind of Coleus (it doesn’t matter if it is an annual or a perennial) needs periodic feeding. The first introduction of nutrients is carried out two weeks after the dive of the seedlings, for which complex fertilizers are used. Each pack contains instructions with recommended doses, but for young sprouts, it is better to reduce the indicated dosage by 3-4 times.
During the period of active growth, Coleus is fed weekly, adding a mineral complex of fertilizers to the flower, intended for decorative leafy plants, but the growth and color of the leaves is also positively affected by the introduction of organic dressings.
For example, once a week it would be good to use potassium compounds for fertilizers (0.5 g per 1 liter of water), although in winter the frequency of such supplements should be reduced to once a month, using half-diluted fertilizers.
How to make Coleus compact shape, trimming plants
It is necessary to care for the flower Coleus (both indoor and garden species) in a certain way, and it is not limited to irrigation and fertilization.So, the plant also needs periodic pruning, although garden species need this procedure much less often than their indoor counterparts.
It helps to give the plants a compact and neat form, as well as save them from the emerging inflorescences and wilted leaves, which adversely affect the decorative functions of the flower. Pruning is carried out before each new season and helps to extend the decorative properties of the plant for at least two years. During the procedure, all shoots are cut at a height of 5-7 cm, and the resulting cuttings are often planted in the ground to produce a new plant.
Coleus breeding methods
Coleus breeds in two main ways: using cuttings and by sowing seeds. Cutting is the most popular method, which allows you to quickly get new large and bushy plants.
Cuttings for breeding Coleus are cut in February or March, planting them in a tank with sand or rooting in water. After 7-14 days, roots appear on them, after which these parts of the plant can be planted in peat pots, pinching the tops of the longest shoots.
Seeds are sown in small containers with nutrient soil, after which they are lightly sprinkled with sand (this procedure has already been described above). If the indoor temperature is at an average level (about +20 ° C), then you will receive the first shoots in 1-3 weeks.
After the emergence of sprouts, Coleus seedlings spar in special peat pots filled with nutritious soil mixture, leaf earth, sand and sod, in proportions of 1: 1: 1: 1, after which they are regularly watered until the moment they land in open soil.
Placing young plants in a country bed, you should consider their ability to grow rapidly. Therefore, in addition to timely watering, loosening the soil and regular fertilizing, they need enough space for intensive growth.
It should be noted, and the rapid development of Coleus. Within 2.5 - 3 months, a large and strongly branched plant with large leaves grows from a seedling, and the specimens obtained by grafting grow even faster.To create beautiful bushy flowers, simply pinch the shoots.
Given all the features of the proper cultivation of coleus in the garden, you can create an excellent flower arrangement in which this plant will occupy one of the main places.
