Howdy, this is my first grow attempt at potatoes. i planted the Kennebec variety. I can say potatoes are no where near the high maintenance, daily pest inspection, of squash and zucchini. i'm in OKC. What am i looking for or what is the signal to harvest potatoes?? with what little effort these took, provided i get a return, i could see putting these in again. the black tubing is the end of my drip irrigation. i ran it over there, planted a squash beside the drain end. the squash bugs haven't caught on yet. I'm looking for them and eggs with soap in hand. thanks much.
