We have Raccoons, Deer, Bear, Fishers, All sorts of Rodents, and have not lost Potatoes. We use Hardware Cloth Cylinders for the Potatoes. Plants end the season nearly Four Feet Tall, Three or so Feet across. Then, as we need them, we unlace the hardware cloth cylinder(s) and take what We need.
Didn't put any in this Year, as am an "inside cat" for another Year. Maybe next Year.
