- Water
The knotted cranesbill should be watered deeply once a week, allowing the top inch of soil to dry out between waterings. Watering should be done at the base of the plant, avoiding splashing water on the leaves to prevent fungal diseases. In hot, dry periods, increase frequency to ensure the soil remains moist but not waterlogged. Generally, using about one gallon per plant will provide adequate moisture, but this can vary with size and environmental conditions.
- Light
The knotted cranesbill thrives best in partial shade, though it can tolerate full sun in cooler climates. Ideally, place the plant where it will receive morning sunlight and afternoon shade to protect it from the harsh midday sun. A spot under dappled light, such as that provided by open canopy trees, is also suitable for encouraging healthy growth.
- Temperature
The knotted cranesbill prefers temperatures between 50°F to 75°F but can tolerate a range from 40°F to 80°F. Extreme temperatures below 40°F can damage the plant, and above 80°F, extra shading and water may be required to keep the plant healthy. Protect the plant from frost and extreme heat to ensure its longevity.
- Pruning
Pruning the knotted cranesbill promotes healthy growth and prevents disease. Deadhead spent flowers regularly to encourage continuous blooming. After the first flush of flowers diminishes, cut back the entire plant by one-third to rejuvenate foliage and set new buds. The best time for major pruning is in early spring or after the flowering period ends.

- Life cycle
Geranium nodosum 'Silverwood', commonly known as knotted cranesbill, begins its cycle by germinating from seed in suitable soil conditions, typically in the spring. The seed sprouts, growing into a small seedling with characteristic leaves; during this stage, the plant establishes a root system and begins vegetative growth. As the plant matures, it develops a clump of foliage and, in late spring to summer, it produces small, white to pale lilac flowers with contrasting veining, attracting pollinators for sexual reproduction. After pollination, the plant forms seed capsules that, when ripe, forcefully eject seeds to propagate the next generation. Throughout the growing season, it continues to produce leaves and can spread slowly through underground rhizomes. Finally, as a hardy perennial, it goes dormant during the winter, with the foliage dying back, then re-emerges from the same root system the following spring to repeat the cycle.
- Propogation
Propogation time
Spring to Early Summer
The Knotted Crane's-bill 'Silverwood', can be propagated by division, which is the most popular method for this perennial plant. This process is best done in the early spring or fall, when the plant is not in active growth. To propagate by division, one should dig up the whole clump of the plant, ensuring a good portion of roots and crowns are included. Gently separate the crown into smaller pieces, each with roots attached, using your hands or a knife if necessary. Replant the divisions at the same depth they were growing at previously, spacing them about 12 to 18 inches (30 to 45 centimeters) apart to allow for growth. Water the new plants thoroughly to help establish them. This method allows gardeners to easily multiply their Knotted Crane's-bill 'Silverwood' while also rejuvenating older plants.
