Tanacetum balsamita subsp. balsamitoides

Planting out pot grown young plants into containers or in borders during early spring

Sow Outside: Cover seed. Beginning of spring or autumn. Spacing 8 to 30 inches (10 to 75 cm). Sow Inside: Germination time: three weeks to two months. Temperature 55°F (13°C). Two months in advance. Transplant outdoors just before the expected last frost or in autumn.

Place two hand forks back-to-back near the middle of the plant. Gently push the handles back and forth so that the prongs gradually tease the plant apart. Repeat the process with each portion to divide the plant into more sections, making sure each section has a healthy bud. Discard the old, woody growth from the centre of the plant. Some fibrous-rooted perennials, form a loose crown of many stems and can be simply pulled apart by hand without damaging the plant. You can also take off separate stems growing at the edge of the plant, just make sure each portion has its own roots.
