I have squirrels digging up not just my beds but the whole yard.My dog passed last year and he would chase anything that moved.I once seen him run into a tree while looking up chasing a bird.
He was a mini Dachshund and he chased everything except the deer when they had babies because they would chase him off.
Seriously,I love watching the squirrels & they need to eat as well and they aren't eating any plants.They are digging for acorns & end up digging up plants.Which this has led to some Sedum cuttings getting dug up & i don't see it before the little rooting are uprooted & cooked in the sun.They weren't a problem until this.
I have some of the plantskydd but it says there's a granular type for smaller rodents rabbits,squirrels etc... I can't find it for sale any closer than Atlanta.Ordering it is an option it's $10. for 1lb. but $13. for shipping & handling.
