This past weekend, I transplanted several of my perennials, after adding compost etc. It took me several hours, and the plants were out of their soil for a while while I was digging, tilling, etc. Now several of them are really droopy, even some that weren't moved. I've watered them deeply twice, and pruned back the most sickly looking leaves. Naturally my parents are coming today and its the 1st time they've seen my garden.
Herbaceous perennials come back from their roots.
Yes, they look droopy, but that doesn't mean they are dead. I'd wager that more than half of them will come back next year. Mine is taking over my garden. The nuts have not yet dropped. But at least on mine I didn't notice a fungus.
