We live on the coast, about 3 blocks from the beach and are in the process of building raised beds. We have a 300 gallon stock tank and wondered if it is feasible to grow asparagus in it, this is partly because we have an active mole population! The other alternative would be to line a trench with hardware cloth...how deep would it need to be? Thank you so much for this incredible website, it is such a great resource.

You could definitely grow asparagus in a container if it is at least 18 inches deep and 12 inches in diameter so it sounds like your stock tank might work. You will have to ensure it is modified to allow good drainage.
Moles are insect & earthworm eaters. They can, however, damage plant roots inadvertently while burrowing. Gophers are definitely plant eaters. If you wanted to use a hardware cloth (1/2 inch mesh) fence to help prevent gopher/mole damage over a larger area, it would need to be 24-30 inches deep with the end bent outward into an "L" shape. To protect raised beds, you can line the bottom with 1/2 inch mesh hardware cloth.
