Canna Lily Leaf Browning: Watering and Fertilizing Fixes

Potted cannas grow well but older leaves brown at edges within 3–5 days. No blooms yet. Zone 5, overwintered indoors.

Likely Issues

• Watering: Inconsistent – too frequent or too rare. Use weight method: water thoroughly, wait until pot feels light.
• Fertilizing: Heavy feeders – need regular fertilizer. Get canna-specific fertilizer at garden center.
• Crowding: May need division next spring.

Weight-Based Watering

1. Water until heavy.
2. Don't water again until pot feels considerably lighter and soil surface pale.
3. Frequency varies: daily to monthly depending on conditions.
