Don't ringbark my trees

In my garden I have a small orchard. It is an enclosed area with a corrigated iron fence that also is my chook run and my bunny exercise yard. Unfortunately the bunnies like the apple trees and nibble on them. I have tried many things to deter them, mostly small fences and netting or shade cloth surrounds to deter them.

Over winter I have not done much weeding and many stinging nettles have grown up inside the wire cages at the bottom of my trees. This has also kept the rabbits from touching the trees. Now all my fruit trees have stinging nettles growing at their base.

A trial of a bed of lettuce with nettles around it also proved successful. Just before the nettles flower I put them in my compost. Some compost bays  and bins I let the chook's scratch in and some I like to keep them out awhile, so throwing nettles on top of the bays, stops the chook's as well. I recently made soup with stinging nettles in it. They don't sting when cooked and have good nutritional value.
