|My gardenias bud but then turn brown, what is the cause of this?|
|You've pinpointed the most difficult part of growing gardenias: getting those buds to open. The plants require high humidity and lots of water. Gardenias are finicky, and any change of location or humidity or sun can set them back. Spider mites can also cause bud distortion, and mites also thrive in dry conditions. Look on the undersides of the leaves for tiny black specks and whitish webbing. If you find the mites, use insecticidal soap or a neem-based insecticide to control them. Routine misting with water also helps raise the humidity and control mites. Hope this helps!
