What you need is pieces of pipe painted green that stick up about an
inch above the mown height of the grass as plant markers. I used old
jackhammer bits to mark some things near the edge of my property after
informing the neighbors lawn service that he had run over my horse
radish, bee balm, and blueberries.
The second time he ran over my stuff ate an 18 hp mower , there has
been no third time.
Wire coat hangers are an interesting thing too.

How about live 220 lines *very* shallowly buried?
