I remembered as I was washing spuds on the deck and made sure to edit in the tag. The cover seems to provide a few distinct advantages: less weeds, no direct sun contact on 99% of the potatoes, and improved moisture retention. I am finding that my soil compacts pretty hard beneath the plants so the spuds tend to grow up rather than down. I'm curious to see your output.
I have a slew of rubber boas around my farm which makes me very happy. They probably hate it when I find them and drag them into the light since they are nocturnal, lol.
