Q.What to do with calla lily
The calla lily (in a pot) bloomed in the spring and over time looked like it was getting another bloom but it never did open. It’s head drooped and remained green. Can I remove it and plant it?
A Calla Lily flower will not root.
You can divide a plant to create more plants if the pot is crowded.
If you plant didn't bloom it could be a few different reasons.
