Q.How Do I Keep Canna A/k/a Cannasol Plants Alive After They Have Bloomed?
The leaves get black spots and then curl, usually after flowering. The plant gets plenty of water and sun (about 4 hours in the afternoon.) I live in Orlando.

It sounds like they get too much water and not enough sun! This will provide the conditions for bacterial infections to take over.
