First, replenish water.

cause

If the old leaves of osmanthus fragrans are curly, it may be because of long-term water shortage. Without water supplement, growth will naturally have problems, leading to poor growth and weak growth. After a long time, the upper leaves can't absorb water, which causes the old leaves to curl.

solution

Replenish water regularly and water the roots of osmanthus fragrans to ensure that the roots can absorb water normally, so that the leaves will come back to life.

Second, exposure to the sun

cause

In the process of growing up, you need the supplement of sunshine. If you don't see the light for a long time, you will naturally have a tendency to roll.

solution

In the growth and maintenance, especially in the vigorous growth period, it is very important to see the light reasonably.

Third, drainage and flood control.

cause

Not only will the lack of water cause the old leaves to curl, but if it is watered too much during the growth process, the roots will rot, and the transportation function will be problematic, which will also make the old leaves curl.

solution

Once too much water is applied, it needs to be discharged in time to avoid waterlogging, and it can be poured thoroughly every time.

Fourth, natural metabolism.

cause

If the maintenance method is normal, the curl of old leaves may be a natural situation and belong to metabolism.

solution

In this case, there is no need to interfere, just remove the rolled leaves.
