The reason why hibiscus leaves curl

1. Pests

When the cultivated hibiscus flowers are attacked by insects, many insects will easily appear on the back of the leaves, which will cause the leaves to curl over time. The insects on the back of the leaves are not easy to be found, so if this happens, you must carefully check whether there are insects. If there are, you must first determine what kind of pest it is and use targeted medication as soon as possible.

2. Lighting

During normal maintenance, it should not be exposed to the sun. It does not like strong light. If it is placed in direct light for a long time and the indoor temperature is very high, the leaves will curl. It should be moved to a place with weaker light for maintenance, and reasonable cooling measures should be taken during hot noons.

3. Amount of fertilizer

Leaf curling is also likely caused by excessive fertilization each time. Hibiscus prefers dilute fertilizers and cannot be given concentrated fertilizers. Too much fertilizer will affect the roots, causing adverse symptoms on the leaves. You need to temporarily stop fertilizing for a period of time. If there is too much fertilizer, you can add more water to wash away the fertilizer. After the leaves recover, just add a small amount of fertilizer.
