How to raise seedlings of Lagerstroemia indica seeds

1, sowing and seedling raising. Pick mature capsules in autumn, dry them, crack them, take out the seeds and store them dry. Sow in spring, soak the seeds in warm water for 4 hours before sowing, and accelerate germination with wet sand. Sufficient seeds are planted on seedbeds and sown or spread in open spaces.

2. Cutting propagation. Cutting with hard branches in spring. Before germination, select 1 year-old robust branches as cuttings, and cuttings with a diameter of 0.5 ~ 1 cm are the easiest to take root. In order to improve the survival rate, the cutting substrate was soaked in 50 mg/kg NAA solution for 65438 02 hours. According to the row spacing of 10 cm and the plant spacing of 5 cm, the cutting depth is 3/4 of the cutting length, and 1 ~ 2 internodes are left on the ground.

3. Propagation by ramets. Branching plants before germination in spring. Dig out the new buds around the mother tree, pay attention to keep the fibrous roots, apply plant ash to the wound, and plant directly.
