My husband and I can't agree on this. I've asked my family b/c Mom and Dad always gardened with canning and harvesting a lot, his parents in moderation.
My question is this: When do you harvest potatoes with digging them up with storage for winter?
I welcome you assistance.
When potato tops flower that is an indication that setting tubers.
Potatoes are harvested when the top dies or gets very woody. Therefore, tubers cannot grow anymore.
In the fall, you can leave them in the ground untill frost. This can help the potato skin mature nicely.
