No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your average last frost date. Sow at a depth of 1/4 inch in warm soil and maintain temperatures between 70 and 80 degrees Fahrenheit. Transplant seedlings outdoors after your last frost date has passed.
Move transplants outdoors after your average last frost date. Space them 12 inches apart to allow for full maturity at 24 to 36 inches tall. Handle seedlings gently and allow them to adjust to outdoor light and temperature gradually.
Direct sowing is the recommended approach. Sow seeds outside 1 to 2 weeks after your average last frost date, when soil has warmed thoroughly. Zinnias do not benefit from early sowing; waiting for genuinely warm weather produces stronger plants and faster establishment.
Cut flowers in the early morning when stems are fully hydrated and blooms are fully open but still fresh. Harvest regularly to encourage the plant to produce more flowers. Cut stems at least 8 to 10 inches long to maximize vase life.
Pinch back the growing tips when plants are 6 to 8 inches tall to encourage bushier growth and more flower production. Deadhead spent blooms regularly throughout the season to extend flowering and promote new flower formation.
