❓ Frequently Asked Questions

Q: How do I plant Canna Lily bulbs (rhizomes)?
A: Plant the rhizomes horizontally with the 'eyes' or growing points facing upwards, about 4-6 inches deep in well-draining soil after the last frost date, ensuring soil temperatures are consistently above 60°F (15°C).

Q: Can Canna Lilies be grown in pots?
A: Yes, Canna Lilies are excellent container plants. Choose large pots (at least 15-20 inches in diameter) with good drainage to accommodate their robust root system and provide consistent moisture.
