I have almost 200 fruit trees from 1-4 years old. I mulch them with wood chips and most have approx. 2-1/2" diameter white plastic corrugated tubing that goes from the soil to 18 - 24" above ground. I also push the mulch back a couple inches from the trunk of the tree.

I'm finally getting to the point where I should get some fruit and the last thing I want is lose a bunch of trees to some stinking mice!

I haven't had vole problems so far but I certainly have them on my land as I see them regularly in a cats mouth and running for their lives when I mow a high area.

Is the plastic an adequate barrier or have I just been lucky?

If additional protection is advisable what are recommended approaches?

as always thx for help. Mark in MN
