1、 Sun exposure

Reason: camellia is suitable for growing in a soft environment. If the light is too strong and accidentally exposed to long-term exposure, the leaves will be dry and curly

Solution: try to keep it in astigmatism environment at ordinary times. After being accidentally exposed to the sun, you can immediately move it to a cool place to maintain good ventilation and promote plant recovery

2、 Insufficient watering

Reason: camellia is suitable for growing in a humid environment. If it is not watered for a long time, the basin soil will be relatively dry, and the roots can not absorb water, affecting normal growth, resulting in dry and curly leaves

Solution: according to the situation of basin soil, water appropriately and supply water reasonably to maintain growth. During the growth period, water can be poured every 3-5 days to keep the basin soil moist, but excessive ponding can not be generated

3、 Nutrient deficiency

Reason: too little fertilization will lead to weak growth, insufficient absorbed nutrients and curly leaves

Solution: fertilize regularly during the growth period. In the period of rapid growth, thin liquid fertilizer can be applied every half a month, and foliar fertilizer can also be sprayed

4、 Infectious diseases and insect pests

Reason: the curly and blackened leaves of Camellia may be the cause of infection with diseases and pests

Solution: remove the diseased leaves and spray drugs for treatment
