Breeding method of Lagerstroemia indica

1. Softwood cutting: The cutting time is usually from July to August, because the branches are the most vigorous and the survival rate is high at this time. Cut the lignified branches into cuttings about 10 cm long, leaving only 2-3 leaves at the top. When the cutting depth is about 8cm, the water permeability is stronger, and it takes about 15-20 days to take root and survive with plastic film. 2. Hardwood cutting: The cutting time is generally from late March to early April. The method is similar to twig. Select thick annual branches and cut them into 10- 15cm, and cut them into 8- 13cm depth. After that, water them and cover them with plastic film. When the seedlings grow to 15-20cm, uncover the film and maintain.

Second, the sowing method

Sowing is usually carried out in March-April. Sow seeds on the soil surface, and sow 2-3 seeds every 3-4 cm. After sowing, cover with a layer of fine soil, and the seeds will sprout and grow in about 10- 14 days.
