Gary,
So far I haven't seen much damage, except for the ones I've stepped on! That's usually my biggest problem in the spring. That and moles...I almost lost my Sir Richard this winter because a more decided that was the best place for the run.
I dug it up and found that most of the roots were just mush. I had 3 little eyes that looked good, so I'm keeping my fingers crossed. How do they know which plant is a one of my special ones???
