Check out growing potatoes under plastic no dig method. Growing them under plastic with a drip line lets the potatoes grow really close to the surface for much easier harvesting as you really don’t even need a shovel.
The plastic also would help prevent moisture evaporation so you would conserve water over the growing season. Misty Prepper shows how many potatoes they got from using this method. She also shows how easy it is to harvest them with just her hands and a rake to catch any stray potatoes. They got 100 pounds and over from each row. So next year if you are planning to plant potatoes you may want to try this method of growing them under plastic. I may try this as well with the red potatoes.
I have tried the growing potatoes in a plastic garbage can which for us did not work out. We used two big outdoor plastic garbage cans and kept adding dirt as the plants grew all season. At the end of the season we tipped the cans over to harvest the potatoes. They were all small and we only got about three pounds all together, so this is not a method that works, at least not where I am. But this growing potatoes under plastic might just work here and the no dig part I am really digging.
