How to Propagate Yarrows?
Propagation of yarrows is primarily through division, seed sowing, and cuttings. Key factors for successful propagation include full sun to partial shade exposure, well-draining soil, and moderate temperatures. Special considerations for yarrows involve ensuring the division is done in early spring or late fall and sowing seeds on the surface of the soil, as they require light for germination. The difficulty of propagating yarrows is generally low to moderate. For seeds, chilling periods may enhance germination. For cuttings, using a rooting hormone can be beneficial. Steps for division include digging up existing plants, separating into smaller clumps with a sharp knife, and replanting immediately. Seeds can be directly sown outdoors after the last frost or started indoors before transplanting.
