I have some epimediums in a pretty shady part of my yard and some of the leaves are turning brown and dying. It does not appear to be the whole plant but a large portion. This happened in the same spot last year, all the other epis in the yard seem fine. The soil is very good the area is semi under a deck but never gets real dry as I water it, there are Hostas and toad lillys in the same area. The only thing i can think of is there has been a mole working the area. I have googled the daylight out of this and can find nothing. Anyone have any ideas?
