Cultivation method of hibiscus begonia

Growth habit: It is native to Central China, and now it is cultivated from southeast to South China. Strong adaptability, like sunshine, but also able to withstand semi-yin. I like warm and humid environment, but I can't stand drought. The requirements for soil are not strict, and it can grow in barren, sticky and saline-alkali soil. Poor cold tolerance. In Beijing area, the seedlings should be covered with grass in winter to prevent colds. However, seedlings over two years old are not cold-resistant in areas with good microclimate, and have strong germination and pruning resistance.

Propagation method: sowing, layering and cutting can be used. Because hibiscus branches are easy to take root, cutting propagation is often used. Choose the robust 1-

Two-year-old branches were cut into 16 cm long and 10 cm deep. The bed is covered with plastic film. It will take more than a month to take root after transplanting. After rooting, it is planted in the second year and blooms in the third year.

Cultivation management: it is easy to cultivate and does not need special management. From before germination in spring to flowering in summer, it can be watered 3-4 times according to climate change and soil dryness and wetness. If it is drought, the young branches will wither easily and the leaves will fall off early. The flowering period is also shortened. Don't irrigate in autumn, otherwise the autumn shoots will be too tender and the branches will dry up easily in winter. Apply base fertilizer when planting. In the growing season, liquid fertilizer 1-2 times can be properly applied and trimmed to cut off dead branches, weak branches, pests and diseases. It is easy to be harmed by aphids during the growth period, so attention should be paid to prevention and control.
