How to plant Lagerstroemia speciosa and its planting techniques.

Lagerstroemia indica should be planted in the leeward and sunny place with deep soil layer, fertile soil and good drainage. Large seedlings should be transplanted with the ball and the branches should be trimmed properly, otherwise the survival rate will be low. Apply decomposed organic fertilizer as base fertilizer in the planting hole, water it after cutting, and water it 1 time after 3 days. Lagerstroemia indica germinates late. Under normal circumstances, the leaves will only spread from mid-April to the end of April. Because of root injury, the germination of new plants will be delayed. So don't give up management just because you have no job.

The surviving plants are extensive in management, strong in Lagerstroemia indica, easy to cultivate Lagerstroemia indica, and loose in soil requirements, but they grow 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. Generally, water l ~ 3 times in spring drought, and drain well in rainy season to prevent water from rotting roots. Autumn is not suitable for watering. 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. In order to make Osmunda bloom, pruning should be carried out during dormancy. Because the inflorescence of Lagerstroemia indica is planted at the top of the new branches in the same year, the annual branches should be pruned and retracted when pruning, so that the nutrients are concentrated and the branches are strong. Long branches, dead branches, drooping branches, pests and diseases branches, slender branches and endogenous branches should be cut off, and the side branches of Lagerstroemia indica at the lower part of the main trunk should be cut off in time during the young tree period, so that the upper part of the main trunk can obtain sufficient nutrients and form a good crown.

Lagerstroemia indica cultivation and management are extensive, but it is necessary to cut off dead branches, pests and diseases in time and burn them. In order to prolong the flowering period, the branches that have blossomed should be cut off in time so as to germinate again and grow the next round of flowers. In order to make the trunk thicker, you can cut off many flowers and concentrate on cultivating the trunk. Practice has proved that with proper management, Lagerstroemia indica can bloom many times a year, reaching 100/ 120 days.
