I received a 'gardenia' bonsai in the mail from my husband in May. I never considered a gardenia to be made into a bonsai plant. It was healthy but has never bloomed. The picture on the website was of a fully bloomed gardenia.I have not trimmed it, and don't know how. I've had it outside in the sun since May. It's twice a big, but not full & very green like it was at first. Can you help me?
