Color-leaf grass is a warm plant with strong adaptability. The temperature in winter is not lower than 10 °C. It is slightly shaded in summer, and it is full of sunshine. The light is sufficient to make the leaves bright.

Coleus is rich in humus and well-drained sandy loam. At the time of pot cultivation, bone powder or compound fertilizer is applied as the base fertilizer, and the organic liquid fertilizer is applied once every 10 to 15 days in the growth period (the application is stopped in the summer season). When fertilizing, do not spill the fertilizer on the leaves to avoid burning and decay. The color-leaf grass is light, and the shade is easy to cause the leaf surface to become lighter and the plant to grow thin. In addition to keeping the soil moist, it is often necessary to spray the leaves with clean water to flush out the accumulated dust on the leaves and keep the leaves bright. In the seedling stage, the heart should be topped several times to promote the side branches and make the plant full.

After the flower of the color leaf grass, the lower part of the branch can be kept for 2 to 3 knots, and the rest is cut off and the new branch is re-issued. The suitable temperature for growth of colored grass is about 20 °C. The cold dew is moved to the indoor and outdoor, and the room temperature in winter should not be lower than 10 °C. At this time, the water should be dry and wet, keep the soil moist, otherwise it is easy to rotten.

The potted plants are small in size. Generally, the inner diameter of the seedlings is 10 cm in the inner pot. After 20 days to 30 days of maintenance, the plant can be placed up to 15 cm to be placed. The indoor place should be selected from the south window. Keep the soil moist and moderate, fresh air and clean environment. Outdoor maintenance, shading environment should be placed in the summer. The thin liquid fertilizer can be applied 3 times a year. If the main stem grows too high, it should be topped in time. In the case where the seed is not harvested, it is best to remove it at the beginning of the formation of the spike, because the posture of the plant is mostly loose and the posture is reduced after the heading, and the ornamental effect is lowered. At the beginning of October, wintering in the middle and high greenhouses, this period can be re-cut to update the old plants, and at the same time, combined with the turn basin for soil replacement. The maximum diameter of the basin is 14 cm, which is inconvenient to place.

After the ripening of the colored leaf nut, it is easy to fall off naturally. It is also afraid that the storm will blow. Therefore, when the bracts turn yellow, the spikes are lightly cut and threshed one by one. Although some seeds can germinate and emerge, they cannot be cold-resistant. Not the role of self-propagation.

Usually sowing and breeding can maintain the excellent traits of the variety. Some that can not be used to maintain the variety of traits by sowing and breeding methods, need to take cutting propagation.

In the case of a high temperature greenhouse, all seasons can be sown, usually in the greenhouse in March. The fermented humus and the plain sand are uniformly mixed into the seedling pots, and the seedling pots containing the fine sand are soaked in water, and then seeded according to the seeding method of the small seeds, and the thin soil is micro-coated to the glass plate. Or covered with plastic film to keep the soil moist, water supply and pipe protection. Germination is suitable for germination from 25 ° C to 30 ° C for about 10 days. After emergence, the seedlings are planted once or twice, and then the seedlings are placed on the basin. Seeded seedlings, the color of the leaves are different, at this time can be better.

The cuttings can be carried out all year round and it is easy to survive. It can also be combined with plant topping and pruning for cutting shoots, cutting and growing full and full branches. Intercepting about 10cm, inserting into clean and disinfected river sand, the soil part must have roots rooting, shading and maintenance after cutting, keeping the soil moist. . When the temperature is high, the rooting is faster, and the soil should not be too wet during the period to avoid rotten roots. It takes about 15 days to make a root. You can also insert water, use a half cup of boiled water to cool, add the 2-3 sections of the upper part of the growing and growing branches, remove the lower leaves, place in the water, and wait until the white water root grows to 5-10 mm. Planted in a pot.
