Hello, I am new to the UBC Botanical Garden. I have a ZZ PLANT that I started (3) years ago from a single leaf. It has grown to 28" tall and is doing quite well. It has 7 stalks. I give it a good soaking every 3-4 weeks during the winter months and let it completely dry out between waterings. In the summer (2-3 weeks) I have never fertilized my plant because I have no idea what the best fertilizer is for this plant. I have learned that it can produce flowers, although I haven't seen any yet. Can anyone please tell me the best fertilizer to use, soil? and how to get it to produce flowers?? Thanks everyone.
