1. Planting: Plant or repot within 4 weeks of arrival. Choose a sunny location with rich, well-draining soil. For containers, use a pot with drainage holes and add perlite to standard potting mix for extra drainage. Cannas can be grown indoors year-round or moved inside before the threat of frost. Place them in a bright window with direct sunlight and increase indoor humidity, especially in dry climates or during winter. Alternatively, to overwinter plants in zones 2–7, dig up clumps of rhizomes and store them in dry peat moss or coconut coir in a basement or garage that stays around 40–50°F.

2. Watering: Water thoroughly when the top inch of soil begins to dry. Keep the soil consistently moist during active growth, but do not allow the roots to remain in standing water.

3. Pruning: Emma is a self-cleaning variety that does not require deadheading. Trim yellow or damaged leaves as needed. In zones 8–9, after frost blackens the foliage, cut outdoor plants back near the soil line.

4. Fertilizing: Cannas are heavy feeders and benefit from regular fertilization throughout the growing season to encourage abundant blooms. Apply a balanced fertilizer, such as 10-10-10, every 4–6 weeks during spring and summer, following label directions. Avoid overfertilizing indoor plants and stop fertilizing during winter.
