Hi there Josh!
I trimmed my day lilies (sorry, my autocorrect continues to make daylily - plural, into two words and I don't always catch it) last fall, which I rarely do. But I don't think it will stop some of the rot that may be developing. Warm dry temps, followed by lotsa rain, and now cold temps..... I have been removing as much of the leftover dead foliage as possible and removing some of the dead leaves I lightly mulched with last fall. On the other hand I don't want to remove too much because we are still getting down into the 20's at night and I want to protect the more sensitive stuff from the cold....
A conundrum for sure.
I am hoping that this massive rain we had last night ( we needed it) and maybe some warmer temperatures in the future, (not this week, temps in the 30's the next 3-4 days) will help wake up anything that may still be hiding. I am seeing more and more greening up from some.
And it looks like my yellow peony survived, not sure if my chocolate or coral one did yet. Iris are still being slow to green up. My losses in that bed might approach 50% but I am still hoping. As for my digitalis, I think I have lost them, again. I think I am done with that flower
