Many Cranesbill will self-sow, but hybrids may not come true from seed. In those cases you should either use cuttings, which may be difficult to root, or by dividing the roots, which is much easier.
They prefer full sun or half sun, but are tolerant of many conditions. They are cold hardy and will last through autumn. The roots can become invasive.
Most Cranesbill start blooming in May and will continue through the autumn. If the summer heat causes the flowers to fad, trim back and water heavily to promote continued blooming.
Grow in moist, well-drained, humusy soil.
Fertilize at the beginning of the growing season. If you fertilize to frequently you will get awkward growth.
