What if the hydrangea leaves turn yellow?

1. Suitable light

It can endure shade, fear direct sunlight, and can grow normally in scattered light. Too much or not enough sunlight may cause the leaves to turn yellow. The leaves turn yellow and white in summer because they are burned by the sun and the sun is too strong, so they can be transferred to shady and windy places to avoid direct sunlight. If not enough sunlight causes the leaves to turn yellow, it can prolong the time of exposure to sunlight.

two。 Rational watering

It likes places with too much water, but it is also afraid of too much water and drought. If there is too much water, the leaves will gradually turn yellow and lose their luster, which will seriously lead to shedding. If this happens, you should stop watering, loosen the soil and dry the soil, and wait for the soil to dry before adding water. If there is too little water and the soil in the basin is too dry, you should first add a small amount of water, wait 30 minutes and then water again, and sprinkle water on the branches and leaves.

3. adequate manuring

In the process of fertilizing, if too much fertilizer is added, it is easy to cause the phenomenon of "burning roots", causing branches and leaves to turn yellow and fall off. if this happens, we should stop fertilizing and increase the amount of water to make nutrients flow out of the small holes at the bottom, and then wash the soil with water and replace it with new soil. If the soil and nutrients are not changed for a long time, especially if there is a lack of nitrogen, the leaves will lose their green and turn yellow. If this happens, they should be replaced with new nitrogen-containing and loose soil in time, and nutrients should be added every 10 days.
