Wood Crane's-bill prefers consistently moist soil, especially during dry spells and its active growing season. Water deeply when the top few centimeters of soil feel dry to the touch. Avoid waterlogging, as this can lead to root rot. Established plants are somewhat drought-tolerant but perform best with regular moisture. Reduce watering significantly during its winter dormancy period.

Prune Wood Crane's-bill after its main flowering period to encourage a second flush of blooms and maintain a tidy appearance. Cut back spent flower stalks and any leggy or damaged foliage. A more substantial cut-back to near ground level can be done in late autumn or early spring to rejuvenate the plant and remove old, tired leaves.

Wood Crane's-bill can be easily propagated by division in early spring or autumn. Carefully lift the clump, separate it into smaller sections with roots attached, and replant immediately. It also readily self-seeds, so you can collect seeds after flowering and sow them directly outdoors in autumn or early spring for new plants.

While primarily a garden plant, if grown in a container, repotting may be necessary every 1-2 years. Choose a pot only slightly larger than the current one to avoid overwatering. Repot in early spring before new growth begins, refreshing the potting mix with a well-draining, humus-rich blend. Ensure good drainage holes are present.
