Really enjoyed your article on Cannas almost as much as I enjoy Cannas. I'm in Zone 7b near Richmond, VA. Here, the leaf rollers are absolutely prolific, and the moths that lay the eggs must love my gardens. When I'm more conscientious and had more time, spraying them with Neem Oil is helpful. However, I have enough Cannas in different beds to make that too time consuming.
I understand you should not cover Cannas in the ground with heavy mulch, which I did once and lost EVERY one of them. So I'm thinking a light cover of peat mulch on entire beds might be good. What is your opinion ?
