When is it better to cut crape myrtle?

Cutting propagation of Lagerstroemia indica can be divided into softwood cutting and hardwood cutting.

1. Softwood cutting: Softwood cutting is usually carried out in July-August, when the new branches grow vigorously and have the most vitality, and the cutting survival rate is high. Select semi-lignified branches and cut them into cuttings about 10cm long, leaving 2-3 leaves at the top of the branches. Cut about 8cm deep and water the seedlings. In order to keep moisture and keep warm, the seedbed was covered with a plastic film, and a sunshade net was built to shade the sun. Generally 15-20 days can take root. Uncover the film, keep the sunshade net, and water it properly during the growing period. Branches can reach 70cm in that year, and the survival rate is high.

2. Hardwood cutting: Hardwood cutting is generally carried out from late March to early April before branches germinate. Short and thick annual branches were selected from well-growing mother plants and cut into branches with length of 10~ 15cm and depth of about 8 ~ 13cm. After inserting, water and irrigate, and the seedbed is covered with a layer of plastic film to keep moisture and heat. When the seedlings grow to 15~20cm, the film can be lifted to build a sunshade net. Proper watering during the growth period can make the branches grow to about 80cm.
