Sweet Potatoes – When to Harvest
Q: I just dug up my sweet potatoes. They are very small compared to past crops. Did I dig them up too soon? What else could it be?
A: Sweet potatoes should be harvested when the leaves all begin to turn yellow. It’s close to the correct time to harvest them so I don’t think you did it too early. The main reason for small potatoes is growing them in less than full sunshine. Other causes could be lack of fertilizer or water. Consider fertilizing more often next year and be sure to water in dry times.
