When to Grow

Sow outdoors after the final frost, or start seeds indoors about 4 weeks earlier. We advise you to check local frost dates to avoid planting too early, as zinnias are sensitive to frost. The ideal soil temperature for germination is 75 to 80°F. 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

Plant seeds at a depth of about ¼ inch and space them 6 to 12 inches apart to allow good air circulation and minimize disease risk. Lightly cover seeds, as they require some exposure to light for germination. If starting indoors, use biodegradable pots or other means to minimize root disturbance when transplanting​.

How to Grow

Keep soil moderately moist, allowing it to dry slightly between waterings to reduce the likelihood of mildew. Fertilize lightly every 4 to 6 weeks to support growth and flowering. Keep deadheaded to encourage continued blooming.

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.
