Larry, Josieskid, I didn't realize how lucky I was not to have such destructive digging critters. Would hate to have to deal with that! Can see why PVC would be necessary. A lot of my v.blind markers heaved up a few years ago in that year's new seedling bed when we had a very warm winter with lots of freeze/thaw and it's awful to lose the parentage on your seedlings. I had to leave them lying on the ground where I found them and hope I could put them together with nearby seedlings once they bloomed, but for the most part there was too much iffyness to tell for sure.
I know my stepfather in Colorado used to have good luck putting electric fences about 8" above the ground to keep raccoons out, but he just had a relatively small backyard vegetable garden. A lot of work for large dl beds, and racoons can be pretty cagey.
I've got all kinds of critter holes in my daylily beds this year but apparently they aren't interested in daylily roots or markers. I saw a rodent running out of the corner of my eye, but not sure what exact kind it was. Guess that means my weasel is no longer around, so maybe my hens can have some free range time this year.
