Thats how we did it, that being said we pulled them mid July, maybe we didn’t let them grow the whole season
Maybe a little late, there is a saying in Germany „if you plant me in April, I grow when I want and if you plant me in may, I grow instantly“ Maybe that works for your area, too! I would like to plant them earlier next year (this year we had below freezing by the end of April so I planted them in may) good luck if you decide to try growing potatoes again! 🥔
