Coleus is a plant of the Lamiaceae family; people also call it “nettle” because of its external similarity. The leaves are heart-shaped and vary in color; they can combine several shades at the same time: green, burgundy, yellow, red. There are a large number of its varieties (more than 1000), the most common are Blume, Black Dragon, Hybrid, Wizard. When purchasing a plant in a store, you need to pay attention to the presence of shoots, there must be more than one, as well as the absence of a flower, otherwise problems may arise in their maintenance.
Conditions for growing coleus at home
The table shows the basic requirements necessary for flower growth.
Indicators | Description |
Lighting | Avoid direct sunlight; in summer it is better to take it outside (balcony). |
Optimal temperature | In summer +18 °C, in winter +12 °C. |
Watering | Spring-autumn - abundant, lukewarm water, while it is necessary to control the dryness of the top layer in the pot. In winter – moderate, do not allow the soil to dry out. |
Humidity | High, constant spraying of leaves is required. In winter, the ideal place for the plant is the kitchen, where conditions are best during this period. |
Priming | Unpretentious, any soil mixture will do; minerals are added as needed. |
With a lack of light, the plant begins to grow rapidly upward and lose foliage, and its excess leads to stunting and loss of color saturation. Therefore, it is very important to ensure that the light is supplied correctly. The temperature regime is also important - the flower reacts very sharply to its changes. The nitrogen content in the soil helps to increase color saturation.
You can increase the humidity by placing a reservoir filled with wet expanded clay next to the pot.
Red nettle home flower. Coleus flower - house nettle
The beautifully named genus Yasnotkova has more than 150 species, one of which is coleus.
For the shape and texture of the leaves, it received the nickname “nettle”, and for its similar color it is called “poor man’s croton”, because in the beauty of natural patterns it is in no way inferior to croton, but in cost it is significantly ahead of it. So, in addition to attractive colors and an abundance of varieties, coleus can boast a favorable price! Coleus is a tropical flower; it came to us from the forests of Asia and Africa, where it is used not only for decorative landscaping, but also for food. But you shouldn’t follow the example of the aborigines, because we have hybrid varieties growing on window sills, in gardens and indoors, which you can only admire. In nature, coleus are shrubs or subshrubs, 30-50 cm high, whose structure resembles the familiar nettle.
These representatives of the floral world amaze the imagination with a variety of shades and patterns. In terms of beauty, they can give odds to any variegated plant! They can have bright green, brown, purple, yellow, cream, red, burgundy, pink foliage, as well as mixtures of colors to form a unique pattern. The velvety leaves of coleus often have a contrasting edging; they may have dots, stripes, stains, large or small speckles, and a marble pattern. All this gives the flower an extraordinary exoticism!
Do you know that... The closest relatives of homemade nettle are mint, basil, oregano and other spicy aromatic herbs. Although the coleus itself has no smell at all!
By the way, coleus is a flowering plant, but despite all its leafy beauty, its flowering is not particularly decorative. Usually the plant produces an arrow with small white or bluish flowers, like Fittonia.
Gardeners value the Renelta variety (Coleus rehneltianus), which has matte red foliage with green or cream edging.
K. rehneltianus
Coleus pumilus is used as a hanging plant; its lodging stems can be shaped and guided to form a lush bush.
K. pumilus
Bloom's Coleus (Coleus blumei) is a derivative of the Scutellarioides variety, from which countless species with a full palette of colors have been bred. The botanist Carl Blum gave it his name; it was he who developed this variety.
If desired, you can create your own colorful composition by combining different types.
Coleus transplant
This process occurs in the spring after pinching. The acidity of the prepared soil should be within 6-7 pH. However, it does not need to be moved repeatedly because its root system is poorly developed.
The plant is considered an annual, but if certain conditions are met, it can grow for more than one year, you just need to periodically change the soil, and if the pot becomes small, then replant it. In this case, it is necessary to carefully examine the roots for the presence of bad ones (rotten or dead), and, if possible, remove as much old soil as possible.
Pests and diseases
Most often, the stimulus for the appearance of diseases and pests is a decrease or temperature difference. Then it can be affected by fungus, whiteflies, scale insects, mealybugs, and spider mites. They quickly appear on weakened plants.
If pests are detected, the flower should be treated with a biological control agent. It is important to use gloves and a respirator. Make sure that the drug does not fall into the hands of children or pets! This is poison!
Coleus pruning
The flower should be subjected to this procedure systematically. The following reasons for its implementation can be identified:
- better formation of branching, subsequently leading to the creation of a large bush (produced half a month after the dive);
- planting by cuttings (cut off older sprouts);
- reduction in growth (the top is cut off, thereby forcing it to grow in width rather than in height, giving the plant splendor);
- planned pruning (done on flowers older than a year, all shoots are cut off, leaving only 2-3 shoots);
- giving shape, decorating (cut from a formed bush).
Caring for coleus in the garden
Caring for coleus involves abundant watering (especially in hot weather and drought) with settled tap water or rainwater in the evening or morning. The soil should not dry out. When watering, make sure that moisture does not get on the shoots and leaves. Periodically loosen the ground and weed out weeds.

After two weeks, fertilizers are applied to the flowers, halving the dosage indicated in the instructions. In the active growth phase, feed with nitrophoska once every seven days, then with a solution of wood ash. Next, mineral and organic fertilizers are used. This makes the leaves decorative and slows down flowering.
Formed inflorescences are removed so that the bush does not waste nutrients on their development. Pinch when the flower reaches 10-12 cm and trim 2-3 times per season. At a height of 4-5 cm, the buds on top and side shoots are removed, then the flower will take the shape of a ball. Bushes that are too tall and heavy are strengthened with supports.
Coleus (indoor and outdoor) does not tolerate sharp drops in temperature; its growth slows down in cold summers.
Coleus propagation
This process is very easy, their germination rate is 100%. In order to avoid loss of the delicacy of the leaves, it is propagated by seeds (picking) and cuttings (vegetative method).
Sowing seeds, small in size, occurs in the spring in small clay cups (bowls), placing a pre-prepared peat substrate on the bottom and sprinkling a little sand on top. The first sprouts will appear only after two weeks, after which they are transplanted into small boxes with an interval of 2x2 cm, and the soil must be combined: leaf, peat, turf, sand.
It is advisable to include a drainage layer (you can use small expanded clay or small pieces of broken brick) to avoid water stagnation.
After the formation of 1-2 leaves, the plant is transplanted one at a time into pots 7 cm high, and the composition of the soil does not change. Then, after a month, it is moved to larger pots (9-11 cm). In order to increase the number of branches on the coleus, pinching is done, that is, pruning the apical shoots. After just six months, the grown shoots can be used to decorate a room or flower bed.
Cuttings begin at the end of winter (February) and end in May. A specially separated part, approximately 10 cm long, is placed in distribution boxes. The appearance of roots is observed already on 8-12 days. After which it is moved into a pot 9 cm high. This method is the easiest and most reliable, however, when planting seeds, the number of seedlings will be larger.
Maintenance of the plant requires timely watering and high-quality lighting.

Popular questions and answers
We talked about coleus with agronomist-breeder Svetlana Mikhailova - we asked her the most popular questions from amateur gardeners.
How to choose coleus?
When buying coleus, pay attention to its appearance: the leaves should be bright and elastic. If possible, remove the plant from the pot with a lump of earth and inspect the roots. Ideally, they are well entwined and have no signs of rotting.
What should be the pot for coleus?
Pots with a diameter of 9 cm are suitable for young plants and rooted cuttings. For adults - about 20 cm. Coleus look good in clay slides, but in this case they will have to be watered much more often.
Is it possible to grow coleus outdoors?
Can. And even necessary - in the open air they grow much better and look brighter. It is generally recommended to take them out onto the balcony in the summer. But you can also plant it in the garden - at the end of May, when the threat of spring frosts has passed. And in the fall, the plants can be dug up and planted again in the hills. Or cut and root the cuttings and leave the old coleus in the garden.
When and how to take coleus cuttings
In fact, you can cut coleus throughout the year, but, naturally, in spring and summer this percentage is much higher for objective reasons (longer daylight hours, more comfortable air temperature).
Cuttings for rooting are cut only from the tops of healthy shoots that have at least two fully formed leaves.
The length of the cutting, preferably, should not be less than 10 cm, and a cut on a young plant can be easily made with a pre-disinfected sharp knife, blade or scalpel. Scissors are not suitable for these purposes, as when cutting they crumple and deform the plant stem.
If cuttings are taken in winter from coleus growing in a room, then additional artificial lighting is necessary for their rooting.
