I purchased a bonsai gardenia tree last summer & at the time it was loaded with flower buds - not a single one of which bloomed! I realize now I made several mistakes: put it on a bright, south-facing windowsill (when it much prefers indirect light); probably didn't water frequently enough (it dried out between waterings); and didn't use a humidity tray. While I've corrected all three issues, I'm beginning to wonder whether the humidity situation might work better if I housed the tree in a terrarium.
Does anyone on the forum have experience with bonsai plants in their terrariums and/or any other thoughts, suggestions, tips?? Thanks in advance!
