When to Grow

Zinnias should be planted after the last frost, generally in late spring. Alternatively, seeds can be started indoors about 4 weeks before the last expected frost for earlier blooms. This variety matures in approximately 60 to 70 days from sowing, depending on growing conditions. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

For direct sowing, place seeds about ¼ inch deep and space them 9 to 12 inches apart. If starting indoors, use trays with a seed-starting mix and cover the seeds lightly, and use biodegradable pots or other means to minimize root disturbance when transplanting. Germination takes around 4 to 6 days, ideally at temperatures between 75 to 80°F. Once seedlings develop true leaves, they can be transplanted outdoors when the risk of frost has passed.

How to Grow

Water deeply and allow the soil to dry between waterings to prevent root rot. Applying a balanced, slow-release fertilizer at the time of planting is generally sufficient, as excessive fertilization can increase susceptibility to powdery mildew. Pinching young plants at about 6 inches tall encourages a bushier form, ideal for cut flower production.

How to Save Seeds

  • Allow the flowerhead containing the seeds to mature and dry on the plant.
  • Clip off the flowerhead and place it in a paper bag or other container.
  • Working over the top of another clean, opened container, rub the flowerheads between the palms to break them apart.
  • The seeds can be separated from the chaff by first screening and then winnowing.
  • Store in a cool, dry, dark place over winter.
