Landing

If you plan to plant a Coleus in the open field, then the place should be chosen carefully. This plant prefers well-lit areas, due to which the shrub is covered with variegated and healthy foliage. When choosing a place to plant nettles, it is worth attaching importance to some nuances.

• White and red nettles can be planted directly in direct sunlight.
• The variety, which is characterized by green foliage, does not like the brightness of light so much, therefore, during the active phase of the sun, the grower will have to shade the plant. The best option would be to plant a representative of the flora in a shaded place, otherwise it may suffer from burns.

The second important point when planting Coleus is the correct selection of soil. This type of plant can be planted on any soil, but nitrogen and nutrients must be present in it.

The correct substrate contributes to normal growth, foliage beauty and the expressiveness of the pattern on it. The best soil composition for Coleus is as follows:

• black soil - 4 servings;
• pine needles - 2 servings;
• cow dung - 2 servings;
• sand - 1 portion.

For proper preparation of the soil, it must be heated and sieved. Coleus can be planted by seeds or as seedlings. When using seeds, the grower will have to wait longer for seedlings to appear. By planting seedlings, you can quickly get a beautiful decorative dwarf shrub. Sowing of seeds is carried out in the second half of March, after 7 days, shoots begin to appear.

From the moment the sprouts appear, the cover can be removed, and the container should be sent to a well-lit area, the best option for this would be a window in the east or west. The temperature should be maintained at +17.19 degrees Celsius, while it is worth protecting the nettles from the direct influence of the sun's rays. Planting coleus with seeds is an effective method that will allow the grower to become the owner of a chic ornamental plant.

Seedlings should be planted in open ground after thorough heating. If young coleuses were grown on a windowsill, they are transplanted into open ground without effort. When buying seedlings, it is worth considering the color of the foliage and stem, as well as the elasticity of the stem. Planting in open ground should be carried out in the first half of June in warm soil.

The flower grower will have to make the holes of the required size, and then fill them with a nutritious substrate. Planting seedlings should be carried out subject to the distance between plants.

Care rules

In order to grow Coleus at home in an apartment or in a garden in the country, it should be properly looked after. A flower in a flowerbed and in a pot needs moderate irrigation, fertilization and pruning at home, in some situations it should be kept in the shade.

In the warm season when growing nettles moderation of watering is required … For this procedure, it is necessary to use water that has settled. During hot weather, the shrub will need additional spraying, which will not allow the upper soil layer to dry out. In winter, the amount of irrigation decreases, but it is not worth overdrying the land. With a lack of moisture, the plant wilts, as well as the loss of its elasticity.

Perennials and annuals need proper feeding

1. The first fertilization occurs 2 weeks after the dive of the seedlings . Top dressing of young seedlings should be less saturated than indicated on the package, an ideal option would be to reduce the concentration by 3-4 times.
2. In the phase of active growth of nettles, it is necessary to fertilize it every 7 days . For this purpose, it is worth purchasing a complex fertilizer that is intended for this decorative representative. Potash fertilizer is considered a good option.
3. In the winter season, feeding the Coleus should be done once a month ., while it is worth diluting the dose of the substance by 2 times.

A florist should know that do not allow spontaneous growth of shoots … The first pinching is carried out at a time when the plant grows to 10-12 centimeters. After that, it is worth shortening the shoots from the sides, and forming a half-shrub at your discretion. The twigs that are cut can be used to propagate the Coleus. If the nettle blooms at the wrong time, then it throws out an arrow that has no decorative features. It is better to cut the flower arrow, so the plant will save its energy.

In spring and summer, Coleus, which grows indoors, requires similar care measures as for a garden representative. A florist must not forget on the regularity of watering, as well as the introduction of fertilizers with a high nitrogen content, the formation of room nettles . Humidification should be carried out with settled water at room temperature, sometimes using a spray bottle. The flower should be taken out to the balcony, as it has a positive attitude towards fresh air.

In the cold season, the Coleus growing in a pot should be fertilized once a month and watered several times less than in the warm season.

Reproduction methods

Each owner of a decorative coleus should know about the methods of its reproduction. There are two of them: cuttings and seeds. The half-shrub propagates by cuttings is quite simple; for this procedure, you can even use the shoot that remained after pruning. The planting material must be at least 10 centimeters high . It is worth removing the foliage from the lower part of the cutting and deepening the coleus into wet soil.

To create a greenhouse effect, young flowers should be covered with plastic wrap or a plastic cup. For successful rooting, the pot must be shaded at a temperature of 20 degrees Celsius.

After 14 days, rooted coleus can be planted in a permanent place of growth. Some growers place the cuttings of the plant in cups of water, which contains a drug that stimulates the formation of the root system. Containers with cuttings are sent to the windowsill and wait for the roots to appear. After the formation of the root system, young nettles are planted in the soil.

For sowing Coleus seeds, it is worth preparing containers with a shallow depth . A fertile light substrate and seeds are poured into the container. The location of the latter should be carried out on the soil surface, after which the seeds must be sprinkled with sand a little without covering. The last stages of sowing will be to moisten the nettles with a spray bottle and cover the container with a transparent cloth. Germination of seeds is carried out on a warm and light windowsill.

The temperature, which contributes to the rapid and high-quality germination of planting material, ranges from 20 to 25 degrees Celsius. Aeration and removal of liquid droplets from the covering material have a positive effect on the condition of the germinating coleus. The first shoots appear 2 weeks after sowing. At this time, it is worth removing the cover from the container.

For rapid further cultivation to occur, the boxes with vegetation should be defined on the western or eastern windowsill.

Flowering features

The flowering of coleus cannot be called a decorative process, therefore, at this time, many growers do not pay much attention to the semi-shrub. In this phase, blue-violet flowers appear at the nettle, which are collected in complex inflorescences. At this time, the flower spends a large amount of vitality, so the best option after the formation of the inflorescence is to remove it … In some varieties, the flowers exude a pleasant aroma, but the shrubs look inconspicuous at this time.

Diseases and pests

The decorative appearance of the Coleus is influenced by the correctness and regularity of taking care of it. The depressed appearance of a plant is a consequence of various circumstances.

1. High soil weight . Poor drainage causes water stagnation near the roots of the shrub. This situation causes decay of the roots, and the flower, in turn, becomes weak and loses its leaves.
2. Excessive watering . Despite the fact that Coleus has a positive attitude towards abundant watering, it does not tolerate waterlogging. The soil should be kept moist, avoiding swampiness.
3. Not enough water . Uneven watering and insufficient watering can cause the soil coma to dry out, which causes loss of leaves and death of the coleus.
4. Lack of light . Since the nettle is a light-loving plant, improper illumination will lead to a loss of decorative qualities. Poor lighting leads to elongation of the shoots and the absence of a bright color of the leaves.
5. Direct sunlight . Burns on the leaves can occur on a hot sunny day. As a consequence of this situation, the leaves dry and shatter.

In a weakened state, pests such as whiteflies, aphids, ticks, mealybugs often attack the Coleus. If aphids are found on a houseplant, it is worth treating it with a soap-based solution. This procedure is repeated after 7 days. Florists should remember that before treating the nettle with soapy water, cover the soil with material that does not get wet. In the garden, aphids are fought with the help of insecticides, good results are given by "Aktara", "Fitoverm", "Aktellik ".

Whitefly is eliminated by the above methods. To combat ticks, use "Akarin", "Apollo", "Oberon".

Use in landscape design

Currently, the use of coleus in a flower arrangement by landscape designers is not uncommon. A beautiful combination can be obtained by combining plants with a solid color . The most harmonious can be called the compositions of Coleus with the participation of sage, cineraria, lily, daylily, gypsophila. The classic option is the combination of purple nettle with yellow marigolds, red salvia, cineraria with a silvery tint.

Red nettle with silver alissum looks perfect . From several types of coleus, you can create an attractive carpet bed or arabesque. The "Persian carpet" is capable of beautifully decorating the lawn, which includes different varieties of dwarf shrubs. To decorate a small courtyard, you can use a container that contains a composition of colorful coleus, cannes with red leaves in addition to green or yellow flowers.

Dwarf coleus, which is combined with a curb sheared boxwood, is an excellent decoration for rose gardens. Red and burgundy roses can be successfully combined with pale green or golden coleus. Often, ampelous nettles are used to decorate loggias. The balcony, which is decorated with such original bright vegetation, looks unique and attractive.
