Crape myrtle has a strong environmental adaptability, the general culture soil can be applied.
If conditions permit, deep and fertile sandy soil can be selected for cultivation, which is most conducive to the growth of crape myrtle.
Crape myrtle is drought resistant and waterlogging resistant. It can be watered once in spring before germination, and once in autumn after falling leaves. Other times, pay attention to "do not dry, do not water".
Water 1-3 times in case of spring drought; do well in drainage in rainy season to avoid rotten roots caused by ponding; do not water in autumn generally.
The growth of crape myrtle needs sufficient light, otherwise it will cause the situation of few or no flowers in the flowering period, and even worse, it will weaken the growth of the whole plant.
The cold resistance of Lagerstroemia specie is very strong, but it is necessary to do a good job in the cold protection and heat preservation of seedlings.
After three years of cultivation, we can stop heat preservation.
Similar to the time of watering, apply fertilizer once before spring sprouting and once after autumn defoliation.
It can be applied to human excrement and urine or mash dregs, which can promote the growth of plants in the next year to be more vigorous, and the flowering period to be more prosperous and bright.
Since the inflorescence of Lagerstroemia speciosa is growing at the top of the new branches in the same year, it is necessary to cut back the annual branches, which is conducive to the concentration of nutrients and the growth of the branches.
In the young tree stage, the long lateral branches at the lower end of the main stem of the plant should also be cut off in time to reduce the consumption of nutrients and ensure a good crown formation at the upper part of the main stem of the plant.
Crape myrtle is easy to be infested by insects such as scale, yellow thorn moth and coir moth, so measures such as spraying should be taken in time.
