What to do if hydrangea leaves are curling and burning

1. Lower the temperature

Reason: Hydrangeas like to grow in a warm environment and cannot withstand high temperature environments. If the temperature is above 30 degrees for a long time, it may cause the leaves to curl and burn.

Solution: Pay attention to the temperature in summer, move to a cool place as soon as possible, and spray water around to lower the temperature.

2. Poor ventilation

Reason: Hydrangea cannot grow in an airtight environment for a long time. If it is too hot and stuffy, the leaves will curl and burn.

Solution: If you keep it indoors, open the windows more often to let in air and keep the indoor air circulating.

3. Adjust moisture

Reason: It needs an appropriate amount of water to grow. If too much water is given, water will accumulate at the roots, leading to root rot and causing the leaves to curl and burn.

Solution: Pay attention to watering properly at ordinary times. If you water too much, move it to a well-ventilated place to evaporate the moisture in the soil.

4. Reduce fertilization

Reason: Applying too much fertilizer can cause fertilizer damage, which can lead to root burns and curling and scorching of leaves.

Solution: Pay attention to applying fertilizer frequently and in small amounts. If too much fertilizer is applied, appropriate watering is required to promote the dilution of excess fertilizer.

5. Prevention and control of pests and diseases

Reason: If you do not pay attention to maintenance, it may lead to the occurrence of diseases and pests, and problems will occur with the leaves.

Solution: Pay attention to ventilation, disinfect the soil in advance, and spray pesticides when pests and diseases appear.
