Thanks for sharing and I hope that it works out for you! This is how I have grown most of my potatoes over the past few years. I just pull my mulch (mostly wood chips) back and stick them on top of the ground and then bury them in the mulch. I add more mulch as they grow.

So far it has worked great and I have been able to just stick potatoes in all around my perennial plants to get some extra harvest. I don't even water them and they always seem happy. Voles have been my only issue but I still got a decent harvest last year.

Good luck!
