Last year was my first attempt at an all out veggie garden, and it was lots of fun and a smashing success, so I'm pumped to go further with it this year. I planted Yukon Gold, a blue and a red skinned variety last year, and got a nice harvest of new potatoes, but not much of a later harvest of larger tubers for winter storage. How and when do you harvest? If I want mature tubers to store, should I forgo harvesting new potatoes?
I thought I had left enough in each hill to continue growing and maturing, but not sure. In fall they started trying to grow again, but it was too late to leave them. Perhaps I grew the wrong varieties for this application?
