Not a lot of veggies happening at my place, but the Hippeastrums are very happy!
I have found 2 good size exit holes. One right next to the raised bed garden and one right in front of the rhubarb. Stinkers.
This isn't felt paper per se; it's a much stiffer paper. We've been using it as our landscaping paper in the flowerbeds. We dig out soil, put the paper down, replace the soil, then mulch over top. We still have a ton left.
A few years ago, when the snow was really bad, when the weather finally warmed up, we saw mole trails all over the yard; those buggers had been busy.
