Lagerstroemia indica alias, itchy flower, itchy tree, purple flower, how to prune Lagerstroemia indica?

1. Pruning and pruning of Lagerstroemia indica can be carried out in spring. Because there are too many sprouted buds, too many branches of Lagerstroemia indica will be disordered. Therefore, it is necessary to remove excessive buds and control the growth of Lagerstroemia indica branches in order to maintain a stable plant type. Sprouting in spring should be carried out once a week for three times.

2. When pruning Lagerstroemia indica, we should pay attention to how to cut off the branches and leaves after flowering, and cut off the branches that have blossomed on the main stem to the bottom, so that 2 ~ 3 bud points can be stored on the bottom branches, thus promoting Lagerstroemia indica to sprout branches and leaves from the tender buds for secondary flowering.

3. Dense branch thinning In fact, it is necessary to carry out dense branch thinning for Lagerstroemia indica whose branches are too concentrated. The branches that are too dense on the main stem are cut short with scissors after disinfection and sterilization, so that the natural environment where the branches grow is naturally ventilated, there will be no shading problem, and there will be enough light to make them grow vigorously.

4. Replanting Lagerstroemia indica in winter grows slowly in winter. It must be pruned again, and unnecessary and useless branches must be pruned to prevent excessive consumption of nutrients, so that Lagerstroemia indica can store enough nutrients until the buds are pulled out and grow and bloom in early spring. So cut off the branches, leaving only 5 cm long, and cut off the weak branches, dry branches and horizontal branches inside.

5. Professional knowledge to expand fertilizer and water management: Osmunda japonica likes wet geology and needs to be watered, moisturized and replenished on time during the feeding period. Don't run too much water, the soil layer is slightly wet. Water seepage is strictly prohibited. It consumes a lot of nutrients during flowering, so it is necessary to apply fertilizer before flowering to increase phosphorus and potassium fertilizer and reduce the amount of base fertilizer. Plenty of sunshine: Osmunda likes sunshine. When planting, you need to choose well-lit land to get more sunshine. Adequate sunshine can promote vigorous growth and better germination. If you stay in a cool natural environment for a long time, it is very easy to flourish and will endanger flowering.
