My cannas are blooming like crazy and seem to be doing great except for one thing. After just a couple of days new blooms start fading from their vibrant orange/red to a paler and paler color. They do get a lot of sun (abt 9 - 10 hrs.) but I thought they liked a lot of sun. I give them plenty of water.
Is there anything I can do to avoid this? It's happening with a lot of my flowers.
