Alas, two years ago the gophers pretty much told me that vegetable gardening was no longer for me.
It was disheartening to see my healthy three or so foot plants, one by one, first wither (as the roots were gnawed) and then actually disappear into their damn tunnels.
The wife's pet project is a flower garden where we used to have an above ground pool. The gophers actively tunnel, but don't hurt the plants.
