Why doesn't crape myrtle blossom?

Your crape myrtle has grown, all the nutrients in the whole plant are used for nutritional growth, and reproductive growth (flowering) is inhibited. If it is potted, it may be that excessive fertilization has caused the overgrowth of branches and leaves. It is suggested that fertilization should be reasonable and phosphate fertilizer should be applied before flowering. Lagerstroemia indica is a sunny plant, so we should keep enough light. Special attention should be paid to Lagerstroemia indica, which is not suitable for spraying leaf water, and it is easy to cause long branches and difficult to bloom. It is suggested to prune now, cut off overgrown branches and some weak branches, and with scientific conservation, flowers can still bloom this year. In addition, pruning after flowering and defoliation in autumn is also very important, which can remove residual flowers and spikes, preserve nutrients, and remove weak branches, pests and diseases, internal branches and horizontal branches. And concentrate nutrients, so as to have more lateral branches in the spring of next year, which is conducive to flowering. The rapid growth of branches may also be caused by not pruning last year. Plants are too small to bloom, which is also the main reason for not flowering. hope this helps ...
