I have read many time here to bury the hardware cloth 1-2 feet for the run. My husband thinks it will rot out quickly and wants to bury cement blocks and set the hardware cloth on top of it. 2 questions: 1. Will hardware cloth rot? We do live in rainy Seattle. 2. If we do bury cement blocks, how do we attach the hardware cloth? Won't the crafty critters be able to pry a gap? Sorry, it was more than 2 questions!
