What causes gardenia buds to drop

I. Overwatering

1. Cause: when watered too much, it is as if it is soaking in water, the roots will rot, and in addition, soil with too much water affects the roots' ability to absorb nutrients, so the buds drop.

2. Solution: the first thing to do is stop watering. If there is not too much water, you can poke a few holes in the potting soil with chopsticks to increase water evaporation. If there is a lot of water, you need to dig it out of the soil, cut off the rotted roots, and replant it in relatively dry potting soil.

II. Overfertilizing

1. Cause: many people add nutrients when the gardenia is growing buds, but doing so not only fails to make it grow better, it instead burns its roots. This is because the nutrients the buds absorb are the nutrients the whole plant stored earlier; fertilizing now instead increases the burden on the gardenia, so bud drop occurs.

2. Solution: if the situation is not serious, you can water the potting soil so the water flushes out the excess fertilizer, then place stones at the bottom of the pot to increase water evaporation. If the situation is serious, you need to replace it with new potting soil; use a ceramic pot, and the soil is best a sandy soil containing rotted material.

III. Pruning branches and leaves

1. Cause: its roots are very fragile, and repotting easily damages the roots; damaged roots affect the ability to absorb nutrients, so it is not surprising that bud drop occurs.

2. Solution: cut off some excess branches and leaves to reduce water evaporation and concentrate the nutrients, then place it in a cool, shaded spot and wait for it to recover on its own; once it has recovered, just care for it normally.
