Gardeners either love or hate cuttings. Once you’ve got the cuttings bug, it’s hard to control yourself. You’ll eye every plant for its potential of being dozens of plants. Geraniums are easy to root as cuttings. The baby plants take up less space than bringing in the mother plant and they’ll probably have more blooms next season.
Take a look at this step-by-step for making cuttings. The only additional piece of advice I have for making cuttings of geraniums is to let the cuttings sit over night, before planting. Allowing the cut end to callus over seems to help the geranium root, rather than rot in the damp soil. You should feel some resistance when you gently tug on the cuttings in about 4-5 weeks. This tells you the cuttings have rooted and are ready to be potted up and grown as houseplants.
