Why do houseplants lose their flower buds

why do flower buds fall off indoor house plants

Hi Edyth,

There are several reasons why buds fall off of flowering indoor houseplants.

The main one is low humidity. Once the buds appear spray them with warm water to help them open. You can also place a small humidifier near the plant to increase the humidity in the air around the plant. Some plants, like gardenias, need temperatures in the 50’s at night in order for the buds to set. Not many homes allow the temperature in their house to go that low. Buds will also drop off if the soil gets too dry. Hope this information helps.
