by Janet Macunovich Length: 07:08Length: 7:09To divide a plant whose roots form offsets (small plants growing at the base of a larger one), snap the connection between any of the sections to obtain a piece with ample roots and three or more growing points (or “eyes”). Some denser clumps may have to be cut apart. Plants that form offsets include asters (Aster spp. and cvs., USDA Hardiness Zones 4–8), coneflowers (Echinacea purpurea and cvs., Z 3–9), hostas (Hosta spp. and cvs., Z 3–8), tickseeds (Coreopsis spp. and cvs., Z 4–9). In this video, author and instructor Janet Macunovich demonstrates how to divide perennials with roots that form offsets.
