There are many summer flowering plants that can be wintered over if they are brought inside. Perennial bulbs, also known as corms, such as Gladiolas are easy divided and stored. Plants like Dahlias that have finger-like tubers are very similar.
Follow these easy steps for success year after year:
1. Wait for First Frost – Wait for our first seasonal frost to kill off the leaves and stems.
2. Dig It Up – Gently remove the corms or tubers from the soil. If the plants are in a pot simply pour the plant out and shake any remaining soil off. If they are in the ground be sure to dig them out at least 6” – 8” away from where the plant stem meets the soil. This way you will not accidentally damage the root.
3. Let Them Dry – Place the corms or tubers on a layer of newspaper and allow them to dry for one to two weeks in a warm, dry area. Do NOT rinse or wet the roots.
4. Pack Them Up – Place the bulbs and tubers in brown paper lunch sacks. Packed loosely with newspaper. (This will soak up any remaining moisture.) Label the bags with the variety, color of the plant, etc.
5. Storage – Keep the bags in a DARK, dry, well ventilated area with temperatures between 35 and 50 degrees.
In the spring wait until frost has passed, remove your corms and tubers and plant them again!
