Canna Lily Dormancy in Melbourne, Australia

Understanding Seasonal Dieback

Cannas are not evergreen outside tropics. In Melbourne's temperate climate (Zone 9–10), they naturally die back in winter.

Current Care

• Remove spent flowers before seed set.
• Allow foliage to yellow and collapse naturally.
• Cut dead tops to 6" after full dieback.
• Pots can stay outdoors if no hard freeze; otherwise move to protected spot.

Winter Care

Keep soil barely moist. No fertilizer. In spring, repot or divide rhizomes, resume water/fertilizer.

Climate Note

Melbourne winters are mild (rarely below 40°F). Cannas may not go fully dormant but will rest. Adjust care to local conditions.
