How to treat yellow leaves of mulberry peony

1. Supplement sunlight

It cannot tolerate shade. If there is insufficient sunlight in the growing environment, the leaves will easily turn yellow. You can supplement sunlight appropriately, but you cannot expose it to the scorching sun. The intensity of sunlight is relatively low in winter, so it can be fully exposed to it. Especially before flowering, more exposure to sunlight can promote photosynthesis and is more conducive to bud formation.

2. Apply fertilizer

It is a plant that likes fertilizer very much. It blooms in large numbers and has a large demand for fertilizer. If it is not given enough fertilizer, the plant will grow poorly and the leaves will naturally turn yellow and become weak. You can apply fertilizer according to the growth trend and maintain a balanced ratio of various nutrients, but do not use too much fertilizer at one time, and avoid using raw fertilizer or concentrated fertilizer.

3. Adjust moisture

Water application is a very important aspect. If you don’t water the plant for a long time, the plant will lack water and dry up, and the leaves will naturally turn yellow. Too much water causes the roots to rot and the leaves will not stay healthy. You can adjust the moisture. If there is a lack of water in the potting soil, you can supplement it appropriately. If there is too much water, you need to place it in a ventilated place to dry, and cut off the rotten roots in time.

4. Treat pests and diseases

Infection with pests and diseases is also one of the reasons. Ventilate the air regularly to prevent it and spray pesticides when necessary.
