Does my gardenia need fertilizer to bloom?

Yes, a balanced fertilizer for acid loving plants applied during the growing season helps support flower production. Do not over fertilize, as this can lead to leaf growth instead of flowers.

Why do my buds fall off before opening?

This is usually caused by low humidity or sudden changes in temperature. Try misting the plant or using a pebble tray to increase local humidity.

Gardenia: not flowering, causes and fixes

Likely causes

Insufficient light
Most likely
How to tell: The plant looks healthy and green but never forms buds. It is likely sitting in a spot that is too dark.

Temperature fluctuations
Possible
