Is there a crape myrtle farmer in Northeast China? Why doesn't my crape myrtle blossom?

Lagerstroemia indica blooms in summer, even in the northeast. Your problem is light and fertilizer. Lagerstroemia indica needs sufficient light conditions, grows weakly in the shade, has low photosynthetic efficiency, produces less nutrition and is difficult to differentiate flower buds.

At the beginning of flowering, more nutrients are needed to form a good inflorescence. If the soil is poor and the water supply is improper, there will be few or no flowers.

Lagerstroemia speciosa blooms at the top of new branches, and pruning in winter is very important. Lagerstroemia speciosa is very resistant to pruning, even if it is pruned again, it will not die. Generally, weak branches, disease and insect branches, lumen branches and cross branches should be removed. And only keep the thick branches and cut them short to facilitate the growth of the lateral branches in the next spring. After the lateral branches grow in spring, some slender branches need to be thinned to make the nutrients supplied centrally.
