What should the crape myrtle leaves turn yellow?

Exposed flowers are succulent plants and are not tolerant to waterlogging. If water is replenished frequently or watered too much at one time in the management process, it is difficult for plants to absorb it all. After a long time, it will take root and hinder growth, and there will be yellow leaves. In addition, the lack of water is not enough, and it is easy to dry and yellow if it does not absorb water during the growth period. If there is more water, reduce watering and increase ventilation. Replenish water as soon as possible in case of water shortage. It is best to make the soil slightly moist during the growing season, so as to promote better growth.

Second, appropriate fertilization.

Rosa davurica has a long flowering period, more flowering times and more nutrients, so it is necessary to fertilize regularly during the growing period. If fertilization is not applied for a long time, the soil is too barren, and plants can't absorb nutrients normally, so it is easy to turn yellow. In this case, it is necessary to supplement fertilizer as soon as possible. By applying diluted fertilizer solution, plants can absorb it quickly and promote faster recovery.

Third, get more sunshine.

Dewdrop flower is a plant that likes light very much, and its growth period and flowering period are inseparable from light. If it is kept in the dark for a long time, normal photosynthesis cannot be carried out, and the leaves are easy to turn yellow, or even rarely bloom or not. The lamp should be filled as soon as possible. It is best to bask in the sun all day in spring, summer, autumn and winter, so as to grow better and bloom longer.
