What to do if the gardenia buds fall off

1. Adjust fertilizer

(1) Specific reason: Gardenia likes fertilizer, so it is necessary to use some during the flowering period. However, if raw fertilizer is used, or the concentration is too high, it can easily cause the flower buds to fall off.

(2) Solution: Stop fertilizing for a period of time. After the situation eases, you can continue to use fertilizers, but you must choose fermented and decomposed fertilizers and strictly control the concentration.

2. Provide sufficient light

(1) Specific reasons: If the plant is in a dark environment for a long time and cannot carry out photosynthesis, it will cause bud drop.

(2) Solution: Place it in a place where it can receive scattered light but not strong light, and the situation may be alleviated.

3. Spray ferrous sulfate

(1) Specific reasons: Various nutrients are important, and iron deficiency may cause flower buds to fall off.

(2) Solution: Spraying an appropriate amount of 0.2 to 0.5 percent ferrous sulfate aqueous solution can effectively control the falling of flower buds.

4. Proper pruning

(1) Specific reasons: If the branches have not been pruned for a long time, they will become messy and dense, and they will consume a lot of nutrients. If the nutrient supply is insufficient, the flower buds will fall off easily.

(2) Solution: Prune appropriately and remove branches that are too messy, too dense, or old.

5. Prevent and control pests and diseases

(1) Specific reasons: Pests and diseases are also an important reason and can cause large-scale flower bud drop.

(2) Solution: Spray targeted pesticides according to different pests and diseases, and increase ventilation.
