More from Teri:
I like to wear suspenders AND a belt, so I’m thinking of using a combination of 1/2″ hardware cloth AND 6″ of rock at the bottom of my 20″ raised beds. Mostly the rock would be to take up space and provide more drainage and also as a further discouragement to the gophers. But is rock really less expensive than soil?
I think gophers would chew through any sort of plastic–they have chewed clan through plastic valves inside my sprinkler valve boxes…causing me to replace them with brass valves. Take that, you annoying creatures!
Sometimes I feel like Bill Murray in Caddy Shack, but I’m with you on the glass! Yuck!
Answer from Pat:
I probably read your mind, since as soon as I wrote that answer it occurred to me I should have suggested putting rock or gravel under and also nailing on the wire. Many people have done this and so far as I know it works to keep gophers out of raised beds. I am not sure that gravel or crushed rock alone would work because the earth from the raised beds eventually sifts down into it and then gophers would just push the earth and rocks aside and worm their clever way through it.
Yes, of course the gophers would chew through the landscape cloth. That’s a given, but then the idea is they would encounter the broken glass. The cloth would be there indefinitely, despite holes made in it by gophers, to help mark the spot for future removal of the glass. That was the idea, not to keep out the gophers, but the broken glass for sure will do so—not that I am advocating the use of broken glass. Like you, emphatically, I am not. As far as expense, you will need to do the research on that, but I believe crushed rock or gravel costs less than top soil.
