Re: Potato question
I can see where the potatoes might get larger because they would be in soft material and it would be easy to pull back the material to harvest, however I agree with the above post regarding rodent damage. In 1975 a friend told me he simply makes a trench and puts in his potato sets and covers the trench with hay. He said they got big and were easy to harvest. I tried it. I got very nice big, clean potatos but I lost half of them to mice and voles. I would pick out a nice spud and when I had it in my hand the bottom half was gone, chewed off by mice. More work with soil, gotta hoe up the dirt etc, but the critters won't eat them.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
