For groundhogs 6 inches to one foot deep - then one to two feet away
from the fence. An "L" shape is needed. The critters go up to the fence
then try to dig under the fence. They run into the wire and stop. Some
groundhogs can dig three feet deep. Also for the high end it "may" be
best not to secure the top 3 feet of that six foot fence, if the
critters decide to climb it the top, the fence can droop back so they
cannot climb it. Electric wire is cool too - change that - make it hot

So a groundhog will climb a fence? If so I will need to add another
electric wire spaced for the groundhog. Right now I have installed a
3ft rabbit fence with electric wires at 4ft and 5ft. So far so good.

Just some thoughts - Fences are not cheap. It may be best to give the
deer and critters what they want at the outer fringe of the garden.

The deer simply eat too much. Last year I had two dozen tomato plants
and did not get a single tomato.
