Divide spring and early-summer blooming perennials in fall, and get every division back in the ground at least four to six weeks before the soil freezes: roughly late September across the Prairies and northern Ontario and Quebec, early to mid-October in southern Ontario, the Lower Mainland and much of Atlantic Canada. Most perennials need dividing every three to five years. Hosta, peony, Siberian iris, Oriental poppy and coralbells are good fall candidates. Asters and chrysanthemums should wait until spring, and false indigo should not be divided at all.
