Planting Instructions

Plant rhizomes in spring after frost danger passes and soil warms. Loosen soil 12–15 inches, mix in 2–4 inches compost. Dig 4–6 inch deep hole; set rhizome horizontally, cover, firm. Space 1–4 feet apart. Water thoroughly. In short-season areas, start indoors in pots in a warm, sunny spot.

Care

Mulch 2–4 inches to retain moisture and suppress weeds. Cannas like consistently moist soil—water if rainfall <1 inch/week; water containers frequently. Stake tall varieties. Deadhead faded flowers. After frost kills foliage, cut to 6 inches. Lift rhizomes, store in perlite/peat in plastic-lined boxes (not touching) at 45–55°F, off floor. Replant in spring.
