How to Propagate Sterile, Hybrid, Hardy Geraniums
- 1). Cut off dead flowers, seed heads, and dead or dying foliage 4 inches from the crown. Leaving a long stem traps winter snow, helping to keep the geranium anchored in the ground.
- 2). Dig up the geranium plant. Shake off excess soil. Look at the bottom off the plant to see where it naturally splits into separate crowns. Use these natural splits as a guide to where to divide your geranium. Pull the plant apart with your hands, or use a spade or knife to cut it into pieces.
- 3). Immediately replant the best geranium divisions back into the garden. Add bone meal to the planting hole, using more for bigger divisions. Bone meal helps the plant grow new roots. Water the geranium divisions well to help them settle into their new home.
