Through the years I've tried just about everyone for bulbs but A.D.R. is tops. It's a family run business and the service levels and expertise are as good as the product they sell. My clients rave about the results we get with A.D.R. and that makes me happy.

Growing and Maintenance Tips for Canna Tall 'Red King Humbert' (Ships in Spring)

Planting: In spring, plant rhizomes horizontally 3 to 4 inches deep after the last frost, when soil has warmed to at least 60°F. Space 12 to 18 inches apart.
Location: Choose a spot in full sun for best flowering. In hot climates, light afternoon shade can help prevent leaf scorch.
Soil: Rich, well-drained, moisture-retentive soil with a slightly acidic to neutral pH (6.0–7.0) is ideal.
Watering: Keep soil consistently moist, especially during hot weather. Deep weekly watering is recommended.
Temperature: Thrives in 70–90°F. Hardy in USDA zones 8–10; in colder zones, lift rhizomes in fall and store in a cool, dry place.
Fertilization: Feed monthly with a balanced fertilizer or apply slow-release fertilizer in spring and midsummer.
Pruning: Deadheading is optional but helps tidy the plant. Remove spent flower stalks without cutting off developing buds below.
Pest & Disease: Watch for Japanese beetles, caterpillars, and fungal leaf spots. Ensure good air circulation and avoid overhead watering.
Propagation: Divide rhizomes in spring before planting.
