What are the breeding methods of Lagerstroemia indica?

There are three propagation methods of Lagerstroemia indica: cutting, dividing plants and sowing. Cutting: select the old shoots of excellent varieties and carry out cutting in late March. Stout 1 annual branches were selected as skewers, cut into 15cm, planted in loose and fertile soil, and left 1/4 exposed on the soil surface to keep the soil moist. Softwood cutting can be carried out in rainy season. The cutting length of shoots is 12cm, and the branches should be semi-lignified, not too tender. The length of cuttings on the chord should be 3~4 leaves, which are inserted in the soil, and the chord is 2/3 or/1/3. Shading and moisturizing after cutting can take root and survive in 30~45 days. Plant division: In spring, you can cut new plants from the roots of Lagerstroemia indica with a sharp knife or shovel, and the roots must be planted separately. Sowing:10-1/autumn harvesting, sowing in sand bed in March-April of the following year, and fertilizing when the seedlings sprout to 15cm. Fertilize once every 2~3 weeks. Generally, sowing seedlings can bloom in about 3 years, and they can also be planted.
