What To Know
- Dig a hole that is twice the width of the rhizome and deep enough to accommodate it entirely.
- Place a thin layer of sand or gravel at the bottom of the hole for drainage.
- Dig up the rhizomes after the first frost and store them in a cool, dry place with good air circulation.
Canna lilies, with their vibrant blooms and lush foliage, are a captivating addition to any garden. Planting their rhizomes correctly is crucial for ensuring their optimal growth and stunning display. This comprehensive guide will provide step-by-step instructions and essential tips on how to plant canna lily rhizomes successfully.
Selecting Healthy Rhizomes
The foundation of successful canna lily growth lies in choosing healthy rhizomes. Look for firm, fleshy rhizomes with no signs of rot, damage, or disease. Ensure they have at least one or two growth points, known as “eyes.”
Site Preparation
Canna lilies thrive in well-drained, fertile soil rich in organic matter. Choose a sunny location with at least six hours of direct sunlight daily. Amend the soil with compost or manure to improve drainage and fertility.
Soil Preparation
Prepare the soil by loosening it to a depth of at least 12 inches. Dig a hole that is twice the width of the rhizome and deep enough to accommodate it entirely. Place a thin layer of sand or gravel at the bottom of the hole for drainage.
Planting Depth and Spacing
Plant the rhizome horizontally, with the eyes facing upwards. Cover it with soil, leaving the top of the rhizome slightly exposed. Space the rhizomes 12-18 inches apart for optimal growth and airflow.
Watering
Water the rhizomes thoroughly after planting. Continue to water regularly, especially during hot, dry weather. Avoid overwatering, as this can lead to rot.
Mulching
Mulching around the rhizomes with organic materials such as bark or compost helps retain moisture, suppress weeds, and regulate soil temperature.
Fertilizing
Fertilize the canna lilies every 4-6 weeks with a balanced fertilizer. Avoid over-fertilizing, as this can burn the plants.
Winter Care
In colder climates, canna lily rhizomes need to be dug up and stored for the winter. After the first frost, cut back the foliage and carefully dig up the rhizomes. Store them in a cool, dry place with good air circulation.
Troubleshooting
- Yellowing leaves: Nitrogen deficiency. Fertilize with a nitrogen-rich fertilizer.
- Brown spots on leaves: Fungal disease. Treat with an appropriate fungicide.
- Stunted growth: Poor soil drainage or lack of sunlight. Improve drainage or provide more sunlight.
Takeaways: Nurturing the Beauty of Canna Lilies
