Causes and Solutions for Yellowing Hydrangea Leaves with Dry, Withered Edges

1. Watering in moderation

Cause: Hydrangeas like a moist growing environment. If the potting soil is too wet or too dry, its leaves will turn yellow and dry up, and in severe cases the leaves will fall off.

Solution: Water in moderation; there must be no excess water accumulating in the potting soil. If too much water is given, drainage must be done well. If the air is dry, you can appropriately spray water on the leaves or around the plant to increase air humidity.

2. Scientific fertilizing

Cause: If you usually apply too much fertilizer, fertilizer burn is very likely to occur, the plant's roots will be scorched, and the leaves will turn yellow and dry up as well. However, you should also not go without fertilizing for a long time; a lack of nutrients will also cause the leaves to turn yellow.

Solution: Control the amount of fertilizer applied and apply light fertilizer frequently. If too much fertilizer is applied, water more to dilute the excess fertilizer.

3. Reasonable lighting

Cause: Hydrangeas like partial shade. If they are kept in a dark environment for a long time, they cannot carry out photosynthesis and their leaves will turn yellow. They also cannot be exposed to strong sunlight; in summer, if no shade is provided, the leaves will turn yellow and the edges will also become dry and withered.

Solution: Generally, let it receive enough light. In summer, avoid strong sunlight and it can be placed in a cool spot for care. If the problem is caused by growing in a dark place for a long time, let it get more sun.
