Did I kill them?
A friend generously gave me lots of bearded irises last year. I planted them in the fall, they came up beautifully this spring, some of them bloomed, and they are now starting to get brown, whither and die back. Is this normal? I was afraid of planting them too deeply, but they've got about 1/2 inch to 1 inch of soil over the rhizomes. Is that too much? They are also in a partial shade area (the spot where I want to put them is going to have a lot of work done to it and I want to just wait till that's done before I put them there. They're in the partial shade spot just to keep them alive till next spring). So did I kill them? Are they just going dormant for the summer? Should I dig a few up that lost all their leaves and see if they're rotted?
Thanks for any help, I've never grown irises before.
