There are several key points in planting techniques of Lagerstroemia indica.

Lagerstroemia indica is a precious environmental protection plant in China. Beautiful posture, flexible branches, bright colors and blooming in summer and autumn. It is an important ornamental tree species in summer and autumn gardens. So how to plant Lagerstroemia indica?

How to plant it?

Generally, we plant crape myrtle in spring. Ziwei likes warm and humid climate, abundant sunshine, a little shade tolerance, born in fertile and humid sandy soil, drought tolerance. Both calcareous soil and acidic soil grow well, but they cannot be planted in places with high groundwater level and low humidity. Lagerstroemia indica is also very cold-resistant, and can grow well even in winter when the temperature is very low. Many people like to plant Lagerstroemia indica in the yard, largely because Lagerstroemia indica has low requirements for the growth environment.

How to fertilize?

Generally, crape myrtle management is relatively extensive. But if Lagerstroemia indica can produce gorgeous flowers, it should be properly fertilized every month. Spraying fertilizer in early March, combined application of nitrogen, phosphorus and potassium: applying phosphorus and potassium once from late May to early June to strengthen branches and promote flowers; Apply a flowering fertilizer at the end of July and the beginning of September. The fertilizer is cake fertilizer and water. Only in this way can Osmunda japonica bloom brightly.

How to control pests and diseases?

Lagerstroemia indica, like other trees, also has pests. When we find that Lagerstroemia indica leaves are bitten by insects, we can prepare a bottle of Bordeaux solution or carbendazim solution for prevention and control. This pest must be controlled in time. If Lagerstroemia indica is bitten by insects too much, it will have a great adverse effect on flowering.

How to trim?

Osmunda japonica has strong germination ability and irregular crown, which needs to be pruned regularly. In order to ensure normal flowering and form large inflorescences, we usually choose to prune in winter, and another pruning time is to cut off some residual flowers after Lagerstroemia indica blooms in summer to prevent it from setting seeds, so as to reduce nutrient loss and promote the germination and flowering of new branches. Don't prune or shorten the newly grown branches during the growing period, otherwise it will easily lead to only long branches without flowering.
