This year I installed soil heating cables on three rows. The resulting
increase in growth rate is amazing. Putting them in place and knowing
where they are at so you don't drive a stake through one was plumb
awful.

So, in future it might help to (1) plant some location fixed points
(a rock won't move far from one season to the next), (2) establish a grid
(for building trades, this would be done with stakes and string),
and (3) make a map of where the buried items lie on
that grid.

Athletic field lime-line gizmos might help, too.
