Question: Do Potato Plants Come Back Every Year?

Most of our favorite vegetables—beans, peppers, potatoes, and tomatoes (technically fruits!)—are annuals.

They complete their life cycles in a single growing season, so we have to plant them year after year.

There aren’t many true perennial vegetable garden plants, but there are some that behave like perennials.

Do potatoes keep growing after the plant dies?

After the plants die back, potatoes stop growing, but can be left for several days in soil that is not too wet and in temperatures that have not dropped to below the freezing mark.

Do sweet potatoes come back every year?

To grow a sweet potato vine as an annual, allow it to die back in the winter and then replant in the spring after the last frost date. If you prefer to save the tubers for replanting next season, cut back the stems at the soil line in the fall and dig up the roots.

Does lettuce grow back every year?

Head lettuce will die back, but most leaf-lettuce plants renew efforts to produce leaves, if regularly watered after trimming. Results will often be smaller than the original plant, but you may be able to harvest a second, good-tasting crop within as little as two weeks.
