I also have a gopher problem. I don't have the gophers eating the herbs, only digging tunnels under the plants -- and dangling roots can't survive. If I were going to all the trouble of putting in a whole new bed, I'd rewire.... but I just might use the plastic fence "wire" instead because it won't deteriorate. I haven't tried it yet, but think I might next time 'round.

It's surprising what "critters" will eat. The big 4-footed "gophers" with antlers visit my gardens more (a.k.a. white-tailed deer). But I did have rabbits and woodchucks of the mind to visit and hang out in my gardens until I had my dog chase them a few times. They decided it wasn't safe for them and moved on.

Westelle, do you know anything about the plastic "wire" that they call "landscape fabric"?
I don't know about your gophers, but I think mine would chew through that plastic stuff in no time!
My wire lasted 9 years. NT

I'm not familiar with plastic wire that's landscape fabric. What i did use under a seating area was a heavy plastic fencing material. The holes were about 1". My purpose there was to keep the ground squirrels from undermining the soil under the chairs. Tomorrow I will go out and check on it's condition. I've used wire for years and have had some, but not complete, success.
