Overwintering Canna Lilies in Pots on Long Island

Two Storage Methods

For cannas in pots on Long Island (Zone 7):

Option 1: Keep in Pot (Easiest)

• Move entire pot to dark, cool (45–55°F), dry location (basement, unheated garage).
• Cut foliage to 6".
• Water once monthly—just enough to keep rhizomes from shriveling.

Option 2: Dig and Store Bare Rhizomes

1. After frost kills tops, cut stems to 6".
2. Dig rhizomes, brush off soil (don't wash).
3. Cure 1–2 weeks in airy, shaded spot.
4. Store in peat moss or vermiculite in cardboard box at 45–50°F.
5. Check monthly for rot or desiccation.

Spring Replanting

Pot up in April, water lightly, place in warm spot. Move outdoors after frost danger passes.
