Voles-effective, nontoxic discouragement?
Okay, after at least 3 years of watching plants die, I have figured out it is Voles. Now, I have used the urine, castor oil & water treatment (too soon to know if it will be successful), but I have read that mixing pea gravel in w/ the soil deeply discourages them. Anybody tried this? I have a lot of area to cover, but I thought I could start w/ digging a trench around the outside of one garden and work the pea gravel in about a foot deep, then just gradually keep extending it. I also thought that new plants should be planted w/ pea gravel in the soil. I hope some of you more experienced gardeners will share what worked for you. Thanks, Brandy
