Growing a canna lily from a bulb (technically a rhizome, not a true bulb) is straightforward if you provide warmth, sunlight, and moisture.
1. Choose the right location
- Sunlight: At least 6–8 hours of direct sun daily.
- Soil: Rich, well-draining soil with plenty of organic matter.
- Temperature: Plant after the danger of frost has passed. Cannas thrive in warm weather.
2. Plant the rhizome
- Dig a hole about 5–10 cm (2–4 inches) deep.
- Lay the rhizome horizontally, with the growing eyes (buds) facing upward if visible.
- Cover with soil and gently firm it.
3. Spacing
- Space plants 30–60 cm (12–24 inches) apart, depending on the variety.
4. Watering
- Water thoroughly after planting.
- Keep the soil consistently moist but not waterlogged.
- Once established, cannas appreciate regular watering, especially during hot weather.
5. Fertilizing
- Mix compost into the soil before planting.
- Feed every 4–6 weeks during the growing season with a balanced fertilizer (such as 10-10-10 or 20-20-20).
6. Ongoing care
- Remove faded flowers to encourage more blooms.
- Cut off dead or yellow leaves.
- Mulch around the plant to help retain moisture and suppress weeds.
7. Winter care
- In areas with freezing winters, dig up the rhizomes after the foliage dies back, let them dry for a day or two, and store them in a cool, dry place until spring.
- In tropical or frost-free climates, you can leave them in the ground year-round.
