1、 Lower the temperature

Reason: Hydrangea likes to grow in a warm environment and can't stand the high temperature. If the temperature is above 30 degrees for a long time, the leaves may curl and scorch

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

2、 Poor ventilation

Reason: Hydrangea cannot grow in an airtight environment for a long time. If it is too muggy, its leaves will curl and scorch

Solution: if you keep it indoors, open more windows to breathe and maintain indoor air circulation

3、 Adjust moisture

Reason: it needs proper watering for its growth. Once too much water is supplied, it will cause ponding in the root, rot in the root and curl and scorch the leaves

Solution: usually pay attention to reasonable watering. Once watering is too much, move to a well ventilated place and evaporate the water in the basin soil

4、 Reduce fertilization

Reason: too much fertilization will cause fertilizer damage, resulting in root burns and leaves curling and scorching

Solution: usually pay attention to thin fertilizer and frequent application. Once too much fertilizer is given, it needs appropriate watering to promote the dilution of excess fertilizer

5、 Pest control

Reason: if you don't pay attention to maintenance, it may lead to the occurrence of diseases and pests, and the leaves will have problems

Solution: pay attention to good ventilation at ordinary times, disinfect and sterilize the soil in advance, and spray medicine after diseases and pests
