The stake is a hollow, open-ended tube having a wall of substantially uniform cross-section along at least most of its length, and having an upper edge adapted to support a guide rod or bar and a lower edge adapted for ground cutting. Certain embodiments include pairs of slots for receiving inserts which assist in determining the proper depth to which the stake should be driven.
