Wheat Rye Oat straw
How do you hill potatoes? I started with yard/garden/kitchen mulch, progressed to bags of garden soil, now I’ve moved onto wheat/rye/oat straw. Saw this on an online video. Certainly less expensive than soil!
From what I understand, the potatoes don’t need more soil, just a place for the runners to grow potatoes out of the sun. Hoping this will work!
