No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your last spring frost date, keeping soil temperatures between 65 and 80 degrees Fahrenheit for germination. Transplant seedlings outdoors after the danger of frost has passed and soil has warmed.
Transplant hardened-off seedlings outdoors after the last frost date when soil temperature reaches at least 60 degrees Fahrenheit. Space plants 12 inches apart, or 18 inches between rows if planting in rows. Bury the root ball at the same depth it was growing in its container.
Direct sow seeds outdoors after the last frost date when soil has warmed. Plant seeds on the soil surface or just barely covered, as they need light to germinate. Thin seedlings to 12 inches apart once they develop true leaves.
Deadhead spent flowers regularly to encourage continuous blooming throughout the season, though Dazzler Red naturally produces abundant flowers with minimal deadheading required.
