Indoor Canna Lily: Dormancy Cycle and Winter Storage

Savannah's 4-foot canna lily (since Mother's Day 2010) has browning leaves, 5 stalks, 4 new shoots. Unsure of indoor care; prefers keeping inside in Spokane, WA.

Understanding Canna Biology

Canna is a tropical bulb plant (like tulips) requiring a dormant period. Browning = preparing for dormancy.

Dormancy Protocol

1. Stop watering. Let stalks die back naturally.
2. When completely limp, cut ½ inch above soil (don't damage bulb).
3. Cover pot with black trash bag. Store in cool (40-50°F), dark place (unheated garage/basement). No freezing.
4. After 2 months, check biweekly for new shoots.
5. When shoots appear, move to sunny location. Resume watering.

Spokane-Specific Options

Summer: Plant in ground when shoots emerge (after last frost). Thrives in full sun.

Fall: Dig up, wrap bulb in newspaper, store cool/dark for winter.

Container: Keep in pot (max 14-inch diameter). Cannas have large bulbs but sparse roots.

Produces baby bulbs for sharing. Many years of enjoyment with proper cycling.
