Sowing and propagation of huangweng

From April to may, indoor pot sowing is adopted. The substrate is suitable for mixing fertile and loose rotten leaf soil and coarse sand. Before sowing, it is best to immerse the seeds in warm water for 2-3 days. The sowing depth should be no seeds, and the grain spacing of about 2 cm should be maintained. After sowing, the pot bottom soaking method is adopted to supply water, and then covered with white paper and glass. At the same time, the room temperature is maintained at about 25 ℃, and the seedlings can germinate in about 15-20 days. The seedlings of huangweng grow rapidly

Cutting propagation of huangweng

The cutting propagation of huangweng is generally carried out from May to June. Select the higher growing huangweng plant, cut it about 15 cm away from its top, dry it and insert it in the sand bed. Generally, it can take root about 30-40 days after planting. You can also peel off the germinating seed balls on the mother plant for cutting propagation, so as to take root faster after cutting

Grafting propagation of huangweng

Grafting is also carried out from May to June. It is suitable to choose Tianchi or short wool ball for rootstock, and seedling or germinated seed ball for scion. After grafting, it usually needs to wait 10-15 days to heal and survive< span>
