1、 Cause of flower bud wilting

1. Improper water management: when the crab claw bud has not yet opened, the requirements for water are very strict, and we must not be careless. Keep the humidity in the basin at about 50% all the time. It can't be too large or too small, which will cause the crab claw bud to wilt. Special attention should be paid to avoid being caught in the rain, and the waterlogging should be drained in time after being caught in the rain

2. Improper fertilizer management: the fertilization concentration of crab claw should not be too large or too frequent. It can be properly applied with some thin fertilizer and water to meet its growth needs

3. Improper illumination: crab claw orchid needs eight hours of sunshine every day, and the maximum duration should not exceed ten hours. Especially the stimulating sunshine in summer will also make the flower buds of crab claw wilt

4. Poor ventilation: it may also be the wilting phenomenon caused by the lack of air circulation. Therefore, more ventilation should be given to the plant to avoid the breeding of bacteria and diseases and pests

2、 Pruning

Prune the poorly growing flower buds, so as to ensure that the flowers on the main branches can fully grow and bloom
