How to Grow Cannas Indoors
1. Select the Right Pot and Soil
- Pot Selection: Choose a pot with adequate drainage holes to prevent waterlogging. Cannas thrive in deep containers that allow their rhizomes to spread.
- Soil Type: Use a nutrient-rich, well-draining potting mix. Adding compost or organic matter will ensure the plant gets the nutrients it needs.
2. Light Requirements
- Bright Light: Cannas are sun-loving plants and require at least 6–8 hours of bright, indirect sunlight daily. Place them near a south- or west-facing window for optimal growth.
- Supplemental Light: If natural light is insufficient, use grow lights to provide the required brightness.
3. Watering Needs
- Consistent Moisture: Cannas thrive in consistently moist soil but hate being waterlogged. Water when the top inch of soil feels dry.
- Humidity Boost: As tropical plants, Cannas enjoy high humidity. Mist the leaves regularly or use a pebble tray to maintain moisture in the air.
4. Temperature
- Warm Temperatures: Cannas prefer temperatures between 65°F and 85°F (18°C to 29°C). Keep them away from drafts and cold windows in winter.
5. Fertilization
- Balanced Fertilizer: Feed your Cannas with a balanced liquid fertilizer every two weeks during the growing season. Reduce feeding during the plant’s dormant phase in winter.
