Canna bulbs (rhizomes) should generally be planted about 2 inches below the soil surface. When planting, dig a hole approximately 3 to 4 inches deep, place the bulb with the "eyes" or growth buds facing upward, and cover it so the bulb sits about 2 inches under the soil line
. Spacing depends on the variety, but typically cannas are planted 8 to 12 inches apart for smaller types, and up to 18 to 24 inches apart for taller varieties to allow room for growth
. Some sources suggest planting deeper holes (4 to 6 inches) especially for tall varieties to help anchor the plants
. In summary:
- Plant depth: about 2 inches below soil surface (dig 3-4 inch hole)
- Orientation: eyes facing up (or sideways if eyes are hard to find)
- Spacing: 8-12 inches for smaller types, 18-24 inches for tall types
This ensures good sprouting and stable growth for canna lilies
