If you are disappointed by how your hardy geraniums are flowering, or the clumps are going bare in the middle, then it is time to divide and rejuvenate them. This easy task can solve problems with poor flowering, and you get new plants for free.
You can divide hardy geraniums in the fall or spring, and it is a maintenance job best done every few years. When working at the world-famous Hidcote Manor Garden in the Cotswolds, I was involved in dividing many clumps of hardy geraniums as part of a redevelopment of the planting beds in the Pillars garden room.
