The flowering period of hibiscus is very long, which can last for 5-6 months, even in the northern region, it can be open for 3-4 months. Hibiscus usually blooms in the morning, closes at night and blooms again the next morning.
Breeding method:
Hibiscus can be propagated by sowing, cutting and grafting. Cuttings can be combined with pruning and shaping from mid-March to early April. Cuttings should be strong wooden branches, with a length of 10 ~ 12 cm. They should be planted in the open air in red soil or sandy soil to ensure soil moisture, but the survival rate is low. It is best to cut in a seedbed with plastic film to preserve moisture, which is easy to survive at the temperature of 65438 07℃ to 20℃.
Hibiscus has strong adaptability, easy growth and easy cultivation and management. From February 65438 to March of the following year, in the dry season in southern China, hibiscus entered a semi-dormant state, and the management was mainly to water and protect seedlings; From April to June, 5438+ 10 will enter the high temperature and rainy season. In April, the plants can be shortened, the management of fertilizer and water can be strengthened, the development of new shoots can be promoted, and the flowers can flourish.
Propagation by ramets: Before germination in early spring, dig out vigorous adult clumps and plant them with three main branches as 1 clump, with a spacing of 50×60cm.
Cutting: select 1~2-year-old robust and not sweet branches. Cut into small pieces with the length of 15~20cm, prepare a small stick when cutting, insert small holes in the seedbed according to the plant row spacing, then insert hibiscus branches, compact the soil, and the insertion depth is 10~ 15cm, that is, the insertion depth is 2/3 of the cutting, and immediately fill it with water. There is no need to apply any base fertilizer when cutting.
