Cutting propagation of Hibiscus davidianus

Cutting needs to be carried out from May to October. Cutting is carried out in the greenhouse in winter, but the survival rate is relatively high in Meiyu season. The cuttings should be annual and semi lignified, about 10cm long. Leave the top leaves and cut off the lower leaves. Pay attention to the flat incision and insert them in the sand bed. The air humidity should be high. The room temperature should be between 18 ~ 21 ℃, and the roots will be born 20 ~ 25 days after cutting. The rooting period can be shortened by treating the base of cuttings with 0.3% ~ 0.4% indole butyric acid for 1 ~ 2 seconds. When the root length is 3-4 cm, transplant it to the pot

Grafting propagation of Hibiscus davidianus

Grafting takes place in spring and autumn. It is generally used for varieties with difficult cutting or slow rooting, especially double petal varieties with low cutting survival rate. Branch grafting or bud grafting can be used, and the rootstock is Fusarium with single petal flower. The grafted seedlings branch and blossom in the same year

Propagation and maintenance of droplight Fusarium

Fusarium is a positive tree species. It needs to be moved to a sunny place outdoors in early May. This is also the growing season of Fusarium. It is necessary to strengthen the management of fertilizer and water, soil loosening and grass pulling. According to the dry and wet conditions of the basin soil, watering, too dry or too wet will affect the flowering

If the light is insufficient, the flowers will shrink, and the flower buds are easy to fall off. The sunshine should be more than 8 hours a day. Fuso has a great demand for fertilizer, so we should pay attention to timely lighting during cultivation. Potted Fusang is usually out of the house in April. Before leaving the house, change the basin and trim it properly to keep the crown beautiful. During the growth period, the water should be sufficient without water shortage or waterlogging. Generally, it should be watered once a day and once in the morning and evening in dog days. The ground is often watered to humidify and cool down to avoid early falling of flowers. When the weather is cool at the end of October, move the potted plants into the greenhouse and keep the room temperature above 12 ℃. Be careful in the management after autumn and pay attention to less fertilization in the later stage to avoid sprouting autumn shoots. Autumn shoot tissue is young and tender, with weak cold resistance. It will be damaged by freezing in cold days< span>
