When to dig sweet potatoes in Missouri?

In Missouri, sweet potatoes are typically ready for harvest in late September to early October, once the leaves begin to yellow and die back. It's best to dig them after the first frost, as this can enhance their sweetness, but be cautious to harvest before the ground freezes. Use a spading fork to gently lift the tubers from the soil, taking care not to bruise them. Proper timing ensures optimal flavor and storage potential.
