I don't give too much credence to yotubers but...
Saw a guy say plant potatoes shallow and do deep mulch.
I usually plant 6 or 8 inches down, and cover greens as they grow and also mulch. But years now I never get any potatoes off the stems, only at the root area. So is there a need or benefit to me putting them 6-8 inches down, versus just enough to cover well?
