Matters needing attention in changing pots of Lagerstroemia indica, can the Lagerstroemia indica planted in September be pruned?

We all know that the flowering period of Lagerstroemia indica is from June to September every year, so Lagerstroemia indica is also called "Hundred Days Red". Lagerstroemia indica leaves in winter, so the best time to change pots is before the arrival of Tomb-Sweeping Day in spring, and summer is the flowering period of Lagerstroemia indica, so it is necessary to change pots. Here are the details.

I used to change a few pots of Lagerstroemia indica in summer, because I didn't know when to change the pots before, thinking that as long as Lagerstroemia indica is still in the growing period, it can be changed at any time. Of course, I have changed pots and hung Ziwei bonsai. Through practice, Wei Zi can still change pots in summer. However, it must be noted that the flower soil is "wet and dry" and the environment is hot and humid, so it cannot be exposed to the sun.

In summer, it is recommended not to change the pot with bare roots, as long as one third of the flower soil is removed, and then the roots of the old roots can be trimmed. Capillary roots in the protective soil will recover the function of absorbing water and nutrients as soon as possible, which is beneficial to the growth of Lagerstroemia indica after changing pots. If the root wound is around 1 cm, a healing agent should be applied.

Changing pots in summer is the flowering period of Lagerstroemia indica, so all the flowers on the branches must be cut off. Prune branches to the position where flowers can't be seen, and then delete some weak branches, cross branches and long branches to reduce the consumption of water and nutrients. Lagerstroemia indica has low requirements on soil, and is mainly loose and breathable, which is suitable for both acid and alkali. I suggest that you can directly plant Lagerstroemia indica with small gravel of rock and a small amount of humus pastoral soil. Flower soil is simple and easy to configure.

After changing pots, don't think that changing pots in summer must be supplied with water many times, but according to the dryness and wetness of the flower soil, "if you don't do it, you will be watered thoroughly." Humidity can supply water in time, and the roots can breathe more smoothly during drying time. It is hot in summer and sprayed twice a day to moisten branches and replenish water.

After changing the pot of Lagerstroemia indica in summer, I will keep Lagerstroemia indica in a cool and ventilated place for the first 10 days. When the buds of the first wave come out, move the basin to a position with good astigmatism and ventilation. Increasing light and photosynthesis is beneficial to the rapid growth and recovery of Lagerstroemia indica root system.

Through our introduction, I believe everyone has a deeper understanding of the matters needing attention in changing pots of Lagerstroemia indica. Can crape myrtle planted in September of that year be pruned?
