Renovation Pruning

As a perennial plant, Geranium sanguineum ‘Elke’ may benefit from occasional renovation pruning to rejuvenate its growth and maintain its vigor. In late summer or early fall, cutting back the plant to remove old, woody stems and encouraging fresh growth can revitalize its appearance and prepare it for the coming growing season.

Maintenance Pruning

Throughout the growing season, it is advisable to perform maintenance pruning to remove any damaged, diseased, or overcrowded foliage and stems. This not only improves the plant’s overall aesthetics but also reduces the risk of disease and promotes good air circulation around the plant.

By incorporating proper pruning techniques, gardeners can support the health and beauty of Geranium sanguineum ‘Elke’ while maximizing its blooming potential.

Propagation
