Need help with my potted calla lily
I have two calla lilies that I keep as houseplants. The first one I planted as a bulb and have had for a year. It's massive. And it won't bloom. Why won't it bloom? The plant looks great. It continuously gets new leaves but no blooms ever! The other one I bought when it already had a bloom. Soon as I brought it to the house, the bloom started to die. It hasn't bloomed since! It's doing well also. What is my problem? They both sit at south facing window. Plenty of sunshine. I water them once a week when the soil dries and fertilize it every two weeks. Please someone tell me what to do!
