WaterKnotweed cranesbill should be watered regularly, especially during prolonged dry spells. Aim to water deeply once a week, providing about 1 inch of water each time to saturate the soil to the root level. In especially hot or windy conditions, it may require watering twice a week. Avoid overhead watering to prevent leaf diseases, and instead use a soaker hose or drip irrigation. Adjust watering based on rainfall, as over-watering can cause root rot.
LightKnotweed cranesbill thrives best in partial shade, though it can tolerate full sun in cooler climates. Plant it in a location where it receives morning sunlight and afternoon shade, or dappled light throughout the day. Avoid intense, direct sunlight during the hottest part of the day as it can scorch the leaves.
TemperatureKnotweed cranesbill prefers moderate temperatures and can generally tolerate a range from 30°F to 75°F. The ideal growing conditions are temperatures that consistently remain between 50°F and 70°F. However, it can survive slightly lower temperatures during dormant winter periods but should be protected from frost to prevent damage to the plant.
PruningKnotweed cranesbill should be pruned to encourage bushier growth, remove spent flowers, and maintain a neat appearance. Deadhead regularly by snipping off faded blooms. Perform a more thorough pruning in early spring to remove any old or dead growth and shape the plant. Pruning can also be done after a flush of flowering to rejuvenate the plant and encourage a second bloom.
CleaningAs needed
SoilKnotted Crane's-bill thrives in moist, well-drained soil rich in organic matter with a pH that is neutral to slightly alkaline. A mixture that includes garden loam, peat moss, and perlite in equal parts can provide the balance of drainage and moisture retention ideal for this geranium variety. Amending the soil with compost will ensure a nutrient-rich environment for optimal growth.
RepottingKnotted Crane's-bill should be repotted every 2 to 3 years to refresh the soil and allow space for growth. Check the root system annually; if the roots appear crowded or start to circle the pot, it is time to repot into a slightly larger container.
Humidity & MistingKnotted Crane's-bill prefers moderate humidity levels, typical of its natural woodland habitat. While it can tolerate some variation, maintaining humidity around 40-50% is ideal for this plant.
Suitable locationsIndoor

Life cycleGeranium nodosum 'Whiteleaf', commonly known as the knotted crane's-bill, begins its life cycle as a seed that germinates in spring or early summer in moist, well-drained soil. The seedling emerges and develops into a rosette of leaves at the soil surface. As the plant matures, it forms a clump with upright and occasionally sprawling stems, and it displays its distinct foliage which is often variegated or marked with pale zones. Flowering typically occurs in late spring to summer, showcasing white to pale lilac flowers with veining, which are pollinated by insects. After pollination, the plant produces small, beaked fruits, each containing seeds that disperse when the fruit dehisces or is aided by animal movement. The plant may become dormant in late autumn or winter, especially in colder climates, but it is a perennial and will resume growth from its rootstock with the advent of warmer weather.
PropogationPropogation time
Spring-early summer
The Geranium nodosum 'Whiteleaf', commonly known as the Knotted Crane's-bill, is often propagated through division. This is typically done in spring or autumn. The process involves gently lifting the parent plant from the soil, making sure to keep a good amount of roots attached, and then dividing it into smaller sections. Each section should have at least one shoot and a portion of the root system. The divisions are then replanted at the same depth they were originally growing and watered well. This method encourages quick establishment with minimal stress to the plants, enabling the gardener to increase their stock efficiently.
