Geraniums are dependable, hardy plants that thrive in most locations. The plant is known for its variety of colors and scented foliage. Geraniums have fleshy, thick stems that hold moisture. This enables it to withstand being stored over the winter without having soil around its roots. After the dormant season, replant them for spring blooming.
Dig up the plants before the first expected frost in your area. Shake the plants gently to remove the soil from its roots. Remove all of the soil.
Choose your storage option. Hang the plants upside down in a dry area, or place each plant into a brown paper bag. Whichever option you choose, store the plants in an area where temperatures do not exceed 50 degrees Fahrenheit or fall below 32 degrees Fahrenheit.
Check the stems of your plants every 2 to 3 days. If the stems appear to be drying out, mist the plants with water. It is normal for the leaves to dry out and fall off.
Soak the roots of the plant in a bowl of water for 2 hours every 3 weeks to keep the stems alive. Allow the roots to dry thoroughly before returning the plants to storage.
Take the plants from their storage area in early spring. Cut off and remove any dead spots on the plants.
Prepare a mixture of water and all-purpose liquid plant fertilizer. Follow the manufacturer's mixing guidelines. Soak the roots of the geraniums for 3 hours in the water/fertilizer mix.
Plant the geraniums in pots that contain potting soil. Water gently. Water the plants whenever the soil surface dries out.
Place the pots in a sunny, indoor spot.
Transfer the plants into the ground when all threats of frost have passed in your region.
