What to do if gardenia buds fall off

Gardenia bud drop - overwatering

Gardenia is a plant that likes water, but when it is cultivated, if it is too large, water will accumulate in the pot, and the roots will lack oxygen and rot, which will cause the flower buds to fall and even the leaves to turn yellow.

Generally, when the gardenia buds appear, you should start to control watering, and water it only when the soil is dry. If the buds have already fallen, stop watering first, raise the flowerpot, and then loosen the soil. After the water is dispersed, gradually resume watering. You can water less and spray more.

Gardenia bud drop - too much fertilizer

When growing gardenias, do not apply too much fertilizer when the buds begin to appear, so as to avoid damaging the roots due to hypertrophy and causing the buds to fall off.

Generally, when the gardenia buds are growing, you can apply some phosphorus and potassium fertilizers before that, and stop fertilizing after the buds appear. If the fertility is insufficient, you can also apply a large amount of topdressing, but you can only apply some decomposed thin liquid fertilizer. If buds fall off due to fertilization, you need to replace the potting soil to encourage the growth of new roots.

Gardenia bud drop - pests and diseases

Pests and diseases are also one of the reasons that cause gardenia bud drop. When gardenia suffers from leaf spot disease or is attacked by pests such as red spider mites and scale insects, the plant will develop lesions and may cause bud drop.

When growing gardenias, it is very important to prevent and control diseases and pests.

Gardenia buds falling - dry air

As mentioned before, gardenia is a plant that likes water. If the air is too dry during the cultivation process, it will cause the buds to fall off.

Therefore, in the process of growing gardenias, it is necessary to maintain a high air humidity, and frequent spraying of water is a solution.

Gardenia buds falling – poor air quality

Poor air quality mainly means that the air contains many substances that are harmful to gardenias, generally sulfur dioxide and hydrogen sulfide, which will have an adverse effect on the growth of gardenias and cause their buds to fall.

Therefore, when growing gardenias, you must ensure that the air is fresh and try to stay away from heavily polluted areas.
