Lily bones turn yellow as soon as they grow out, and they will fall off in a few days.

1, there is plenty of light, not sunlight through the glass, but direct light.

2. The planting site should be ventilated. Too dense branches and leaves and poor ventilation will cause fallen leaves and flowers.

3. When the soil is too wet or the phosphorus fertilizer is insufficient, the flower stalk will delaminate until it falls off, and the falling surface is smooth.
