I noticed (or , at least I THINK I did)today while cleaning up iris beds, that the cultivars that seem to have the rot are all planted directly above where the stumps were ground out last spring. Not sure of just WHY that would be? . There is at least 12"-18" of soil over the remainder of the stumps, so I doubt the wood residue rotting away below, is affecting them. Unless, because the stump acts as a "floor" under them, the drainage in those spots isn't as good . Then again ,maybe just coincidence ....Arlyn
