Planting
How to Grow
- Tuck tubers into well-draining soil in early spring after the last frost.
- Water thoroughly to settle the soil and keep it moist during the growing season.
- Pinch out the top growth when plants are 12 inches tall to encourage bushier growth.
- Fertilize every 4-6 weeks with a balanced, water-soluble fertilizer.
- Stake tall varieties to prevent wind damage and support blooms.
- Lift and store tubers in fall after foliage dies back for overwintering in colder zones.
Pro Tip
Plant in full sun with rich, well-drained soil for vibrant, large blooms.
