Cutting of Lagerstroemia hongyun

In order to improve the survival rate of cuttings, cuttings were soaked in water 6 ~ 8 days before cutting. Remember to change water every day. When the obvious irregular tumor appears in the incision, the incision is cut. Cuttings can be soaked in sugar water for 24 hours, which can significantly improve the survival rate. When cutting, tidy up the soil and apply sufficient base fertilizer to make the soil loose and full of water. First, open the hole with a tool, insert the chip along the hole, and then firmly seal the hole. The cutting depth is 2/3 of the cutting length, the plant spacing is 10 cm, and the row spacing is 15 cm. After insertion, water will be poured, and roots will grow in about one month.
