I put some 4 metal fence around the only fruit tree that still is living.
The deer are more than happy to groom the fence interface with the Erf, but leave the tree alone. [I only have to cut the lawn a few times/yr. - mostly to cut the weeds the deer dont prefer to graze]
The other trees will soon be [a small amount of lumber.
I THOUGHT my younger trees were better protected; I doubled down on that after I saw the damage. All is not lost - only ONE will actually die, ringed; tore the bark off ALL the way around.
Jerks! We have acres and acres and ACRES of trees for you to rub on - leave the ones nearest the house - ALONE!
