Cultivation techniques and maintenance of Lagerstroemia microphylla.

Lagerstroemia speciosa has strong adaptability, can be planted in all kinds of soils, is drought-resistant, waterlogged-resistant, and likes sunshine, so it is suitable as an urban ornamental plant. Water properly in dry season, apply some organic fertilizer before germination, leave leaves at the roots after autumn, and cultivate with river mud without sundries to promote growth and flowering in the next year.

Because potted bonsai trees have four basic conditions: thin leaves, dense branches, exposed roots and dry beauty. At the same time, the branches are soft and easy to climb. In the long summer, we can make all kinds of bonsai by setting branches and renovating trees.

Seed propagation is the best way to cultivate Lagerstroemia speciosa, and a large number of seedlings can be obtained. The method is: soak the harvested seeds in warm water at 50℃ 1 day before sowing, and the sowing date can be spring or autumn. Make a seedbed first, and then sow. After the seedlings are unearthed, attention should be paid to shading and watering in dry and sunny weather. Seedlings sown in spring can grow to more than 1 m a year as long as they are properly maintained and managed, and may bloom in the same year. In winter, seedlings in northern areas should pay attention to cold protection. For example, after several years, the clustered branches can be combined into a strange-shaped branch tree and put indoors for viewing.
