Hydrangea leaves turning yellow? Here is how to fix it

1. Suitable light

It can tolerate shade but fears direct scorching sun, and it can grow normally under indirect light. Too intense or insufficient sunlight can both cause leaves to turn yellow. In summer, leaves turning yellow and white is caused by sunburn from overly intense sunlight, so you can move it to a shaded, breezy spot to avoid direct sunlight. If insufficient sunlight is causing the leaves to turn yellow, you can extend the time it receives sunlight.

2. Reasonable watering

It likes places with plenty of water, but it also fears overwatering and drought. If there is too much water, the leaves will gradually turn yellow and lose their luster, and in severe cases they will drop off; when this happens, you should stop watering, loosen the soil to let it dry out, and add water only after the soil has dried completely. If there is too little water and the soil in the pot is too dry, when this happens you should first add a small amount of water, then after 30 minutes water thoroughly again, and spray clean water on the branches and leaves.

3. Reasonable fertilizing

During fertilizing, if too much fertilizer is added, it can easily cause "root burn," making the branches and leaves turn yellow and drop off; when this happens, you should stop fertilizing, increase the amount of watering so the nutrients flow out through the small holes at the bottom, then rinse the soil with water and replace it with new soil. If the soil has not been replaced and nutrients have not been added for a long time, especially when nitrogen is lacking and nutrient supply is insufficient, the leaves will also lose their green color and turn yellow; when this happens, you should promptly replace it with new, nitrogen-containing, loose soil and add nutrients once every 10 days.
