Generally, Lagerstroemia indica seeds are sown or drilled. After sowing, the surface should be covered with a layer of soil about 1-2cm, and covered with a layer of grass to reduce the loss of water and fertilizer in the soil, thus accelerating the germination time of Lagerstroemia indica seeds. After the seeds of Lagerstroemia indica are planted, after about 10- 15 days, the buds sprout one after another, and weeding can be done at this time. When the seedlings of Lagerstroemia indica grow to about 10 cm, it is necessary to carry out thinning treatment, mainly to remove some weak seedlings and pay attention to cleaning up weeds around the seedlings.
