Like high temperature, humidity and sunny environment, not cold-resistant. The optimum growth temperature of color-leafed wood is 20 ~ 30℃, 2 1 ~ 30℃ in March ~10, and 13 ~ 18℃ in March of the following year. The temperature in winter shall not be lower than 13℃. Short-term in 10℃, the leaves are not bright, dull and lack luster. When the temperature is 4 ~ 5℃, the leaves are damaged by freezing, resulting in a large number of fallen leaves, and even the whole plant freezes to death. \x0d\ Caimu prefers wet to dry. During the growth period, the stems and leaves grow rapidly, give enough water and spray water on the leaves every day. However, when the temperature is low in winter, the basin soil should be kept slightly dry. If it is semi-dormancy in winter, excessive water will cause defoliation and must be strictly controlled. \x0d\ colored wood is a kind of light-avoiding plant, and it needs plenty of sunshine during the whole growth period. Its stems and leaves grow luxuriantly, and its leaves are bright and beautiful, especially with red stripes. 50,000 ~ 80,000 lux is the most suitable. If the light is insufficient for a long time, the markings and spots on the leaves are not obvious, lacking luster, the branches are soft, and even leaves are produced. Suitable for loam with fertile, sticky and strong water retention. Mixed soil of culture soil, humus soil and coarse sand for potted plants. \x0d\ Propagation methods include cutting, layering and sowing. \x0d\ Cutting propagation: from June to August, select the top branches, the length is 10 cm, and the incision has milk. After drying, insert them into the sand bed, keep them moist, take root at room temperature of 25-28℃ for about 20-25 days, and plant them in pots after 35-40 days. \x0d\ Layered propagation: The high temperature season in July is better. According to the tree shape of the mother plant, select the top branch with the length of 15 ~ 25cm, cut the stem into a ring with the width of 1cm with a knife, then wrap it with water moss or peat and fix it with a film. Healing and rooting began in about 30 days, and the planting pot was cut off from the mother plant after 60 ~ 70 days. Sowing and propagation: the seeds are mature in July and August, and sown in autumn. The room temperature must be 25 ~ 28℃, after sowing, it can germinate 14 ~ 2 1 day, and can be potted in the next spring. When the temperature is lower than 25℃, the germination is irregular, the germination rate decreases, and even the seeds rot and die. \x0d\ Cultivation and management Potted colored-leaf trees commonly use pots of 20 ~ 25cm, and the bottom of the pots needs to be padded with broken bricks or cinders. Fertilize 1 time every ten days during the growth period or use "Huiyou" 15- 15-30 special fertilizer for potted flowers, and move it indoors in winter. Because the temperature is low, stop fertilizing, reduce watering and spend the winter safely. When changing pots every spring, the plant shape can be properly trimmed and reshaped to maintain its beautiful plant shape and color. \x0d\ Pests and diseases control common black mold and anthracnose, and 600 times of 50% carbendazim wettable powder can be sprayed. During indoor cultivation, scale insects and red spiders often occur due to poor ventilation conditions. Spray 40% omethoate EC with 1000 times solution. \x0d\ The peculiar leaf shape changes and colorful leaf colors of colored wood are amazing.
