Our potatoes have grown very tall..how do you know when to harvest them? With many tjanks Gill

They have probably grown tall because of one or both of two things - too much nitrogen or if they had to compete for light -(tall nearby plants). I think the guide here say 12-16 weeks to harvest. The leaves will die off when it is time to harvest. My plants powered along (fed plenty of composting mulch - then they have just died - only about 12 weeks since shooting out of the ground. I pulled out one plant - a few big potatoes and a few smaller ones. Have left the others in until I need them to eat.
