Annual geraniums, known for their vibrant blooms and low maintenance, can be overwintered for fuller blooms in the following year.
Washington State University (WSU) Extension Clark County Master Gardener Emily Shue explains how to preserve geraniums so gardeners may experience their full potential.
To overwinter a geranium, remove the plant from the soil and brush away dirt while keeping the roots intact. Remove dead leaves and damaged stalks, then cut off the remaining flowers, Shue said.
Then store the geranium upside down in a paper bag or cardboard box in a cool, dry place. Close the container, but do not seal it completely. Airflow will prevent the geranium from molding, Shue said.
Geraniums will shrivel during storage and gardeners will need to trim off dead and withered stems before replanting. Planting the geranium in a pot indoors six to eight weeks before the last frost will bring the plant out of dormancy. After the last frost, Shue recommends planting them outdoors.
