2. water. Brazilian wood is drought-resistant, but it is not watered enough, and there is too much soil in the basin, so it does not grow well. The growing season often makes the soil in the basin wet, especially in the summer when the growth is vigorous, so it is necessary to fully water it. In autumn, the amount of watering should be gradually reduced, and watering should be controlled during the winter dormancy period. If you water it too much, the roots will rot.
3. Fertilization method. Top dressing with thin liquid fertilizer every15 ~ 30 days during the growth period promoted the luminescence of leaves. For varieties with variegated leaves, in order not to make the stripes of leaves lighter, less nitrogen fertilizer and fertilizers with high nitrogen content should be applied. In general, it is possible to spray 20% ~ 25% decomposed cake fertilizer solution, 0.2% ~ 0.3% diammonium phosphate+0.3% ~ 0.5% potassium nitrate topdressing, and 0. 1% urea +0.2% potassium dihydrogen phosphate aqueous solution on the leaves.
4. Temperature requirements. Brazilian wood needs 20 ~ 30℃, and winter can be spent above 10℃. If the temperature is too low, growth will stop. If the temperature and other conditions are suitable, Brazilian wood can grow within one year. When summer is high, proper shading is necessary. The room temperature in winter is not expected to be lower than 5℃, but it is best to be dormant in winter. The dormancy temperature is 13℃. When the temperature is too low, yellow-brown spots will appear on the tip and edge of the blade.
5. Lighting requirements. Brazilian wood has a wide range of adaptability to light, and its preference for light is strong in the shade. However, if it is kept indoors in the shade for a long time, the leaves will turn yellow and the striped leaves will become thinner. There is much sunshine in spring, autumn and winter, especially in winter. Indoor bright place, can be placed all year round. If you want to watch it in a shady room, after appreciating15 ~ 30 days, you must keep in a bright place for a period of time, and then put it in the room for appreciation. Brazilian wood is afraid of direct sunlight, so pay attention to prevent direct sunlight in summer. When maintaining outdoors in summer, you should pay attention to shading with about 50% sunshade, and don't burn the leaves by strong sunlight, and don't affect the viewing effect.
6, pest control. The main diseases are soft rot, leaf spot and stem rot. Ventilation and dehumidification can reduce the occurrence of diseases. After onset, 75% wet chlorothalonil 600 times solution or 70% wet thiophanate methyl 1000 times solution can be sprayed for prevention and treatment. The main pests are red spider, flat beetle, etc. 80% enemies can use 1000 times of liquid to control or spray other suitable pesticides.
7. Precautions. Brazilian wood thrives and forms a large plant. However, if the plant is too high or the lower leaves fall off, it will affect the ornamental effect and need pruning. When pruning, cut forward about15cm from the height and ground, and new branches will sprout and grow during pruning.
