First aid for dicentra exima?
I've got this dicentra exima that I'm slowly torturing to death. It came back last year after I thought I'd killed it by breaking the stem off (horrible trowel accident, I'd rather not talk about it) and then I can't remember what happened to it. (I got married last year; I can't remember lots of things.) But much to my surprise, the poor thing has put up a leaf about the size of a nickel and a flower stalk that's maybe two inches high, complete with flowers. I have to admire its perseverance.
So I'm wondering, what can I do to help this poor thing build up some reserves this year? Should I fertilize it? Do they need lots of water? My bed is kind of dry. I'd really like to make up for past offenses by nursing this poor baby back to health.
