Cutting back cranesbills
Is it too late in the season now to cut back hardy geraniums which have brown or yellowing and mushy foliage? I didn't have the opportunity to do all of my clumps at the normal time. Those I did had a regrowth as expected, but those I left have many dead leaves, some of which I pick off when passing, but that would be a long job to do them all. I'm wondering what state the plant would be in after a severe cut back now? I realize it will look horrible, but will that be it for the rest of the season, and would I be harming the plant?
