UPDATE: I went with two hot wires this year on the Havahart (FI-Shock - 1 mile) electric fence on my 1/4 acre (50x50'). The garden was fine for weeks, then one or more woodchucks began breaching the fence and doing significant damage to broccoli, cabbage, beans and squash. I reconfigured the fence so the upper of the two wires was a ground wire. Fail! I added another hot wire above the ground wire. Fail! I know the fence was powered and there were no weeds to ground it out. I gave up and went to the Tractor Supply store and bought a Zareba 25 mile energizer. I now know that the Zareba outputs 12.2kv while my former Havahart unit only output 2.0kv! So assuming a good ground, this unit delivers a much greater shock. I set it up with 3 hot wires every 4-6" from the ground/each other.
So far....so good. I'm not seeing any more damage or chasing big rodents out of my garden.
Note: I had conventional garden fencing one year, but did not bury it and the woodchuck(s) just dug under. Garden fencing is inconvenient as you need a gate they can't get through. I thought about doing conventional again and burying it with a one foot 90 degree bend but decided I'd try a more powerful electric instead.
And with the electric fence, I can just step over anywhere.
To understand permaculture is simply to look at how nature has been growing things for thousands of years. The 'secret' is simply to keep the soil covered with plants or mulch.
