If you live in areas where dahlias aren't hardy, you must dig them up and store them for the winter.

Bulbs such as dahlia, gladiolus and tuberous begonia are the best for late summer color. In warmer zones they'll come back year after year, but in colder climates where the foliage dies back, it's time to dig up the bulbs.

  • Start by cutting back the foliage of the plant with pruners. Then insert a pitchfork around the perimeter of the plant, taking care that you're not disturbing the root ball. Carefully rock the pitchfork back and forth. Do this until the root ball can be easily removed from the soil. Very carefully pull the soil away from the bulb or tuber.

  • Dry the bulbs by putting them in a sunny location for about two days. This process is called "curing." Curing thickens the bulb and also prevents fungus or mold from developing on moist parts.

  • After digging up your tender bulbs or tubers and curing them (here, an elephant ear), you can take this opportunity to divide them.

  • After the bulb or tuber is dried, remove the remainder of the dried foliage and separate divisions of the bulbs.

  • Once they are cured, place the bulbs in a container filled with sawdust, peat moss, sand or any other type of material that will help keep the bulbs dry. Make sure the tubers are completely covered to block out the light, then store them in a cool, dry location.

    If storing a variety of bulbs, it's a good idea to keep them separated using net or paper bags. Don't forget to mark the bulbs or else you could be in for some surprises next spring.
