What should I pay attention to when planting Lagerstroemia indica?

Lagerstroemia indica is robust and easy to cultivate, and has no strict requirements on soil, but it grows best when planted in deep and fertile sandy loam. Sex likes light, so it should be planted in the lee of the sun or under the roots of the south wall of the courtyard. If the light is insufficient, plants will not only spend less or not, but even grow weak and have small branches and leaves. Lagerstroemia indica is cold-resistant, but it should be well protected from cold and heat at seedling stage, and the adult plants over three years old do not need heat preservation. Lagerstroemia indica is drought-tolerant and afraid of waterlogging. Water it once a year before germination in spring and after defoliation in autumn. If it is not too dry at ordinary times, you don't need to water it. Drainage should be done well in rainy season to prevent water from rotting roots. Fertilization can be applied after defoliation in winter and before germination in spring every year, such as applying human manure or sesame paste residue, which can make plants grow vigorously and flowers big and colorful in the coming year. Generally, pruning should be carried out after defoliation in autumn, and long branches, dead branches, drooping branches, pests and diseases branches, slender branches and endogenous branches should be cut off in time during the young tree period, so that the upper part of the trunk can obtain sufficient nutrients and form a good crown.
