Panicle hydrangeas thrive in Ontario's climate, as they're hardy to USDA Zones 3-8. Plant them in full sun or partial shade with well-draining, slightly acidic soil. Prune them in late winter or early spring, cutting back about one-third of their size to encourage healthy blooms. Mulch around the base in winter to protect roots from freezing, and water regularly, especially during dry periods.
