Gardeners with a frugal tendency often look for ways to preserve plants and create new plants from old plants. When autumn arrives and your geraniums are looking tired and spent, remove the plants from their planting containers prior to the first autumn frost. Because of the extra thickness of geranium stems, geraniums can survive over the winter months as long as you store them properly. Preserve geraniums over the winter and plant them again in the spring.
Dig up the geraniums from their growing location before the first autumn frost. Use the trowel to remove them from the soil and shake as much excess soil from the roots as possible.
Cut a 1-foot-long length of twine for each geranium plant.
Tie one end of the twine around the stem of each geranium plant and tie the other end of the twine to a rafter in the basement. Strive to create a 45- to 50-degree-F environment for the geraniums.
Remove the geraniums from the rafters once each month throughout the winter to soak them.
Fill the bucket approximately three-quarters full with cool water and place the geraniums into the water so they are beneath the surface of the water. Allow the geraniums to soak in the water for approximately two hours.
Remove the geraniums from the water and check each plant carefully. If you find geranium plants with shriveled or decaying stems, discard them.
Hang the geraniums back up in the rafters.
Fill planting containers with potting soil at the end of the winter. Plant each geranium plant in a container and remove any stems that look dead.
Water the geraniums generously immediately after you plant them.
Place the planting containers in a location that receives direct sunlight. Keep the soil evenly moist. Within two to three weeks, you should notice the plants leaving the dormancy stage and beginning to grow new leaves and buds.
Plant the geranium plants outdoors after the final spring frost.
