I would mulch with fine pine shavings from tractor supply and a little sand to keep the snails out. A little Epsom salts will also help the beets grow and deter the snails! I use pine shavings all over my garden between the rows since its cheap and keeps the mud down! Pine needles from under pine trees is also excellent and free. A old pine tree has very dark compost several inches deep under the new needles on the ground!
