How to Germinate Zinnia California Giant Mixed

How to Germinate Zinnia California Giant Mixed (Zinnia elegans)

  • Sow Zinnia California Giant seeds directly outdoors in late spring, after the last frost date, or start them indoors 4-6 weeks before the last frost.
  • Plant seeds 1/4 inch deep in well-draining soil, spacing them 4-6 inches apart in rows.
  • Maintain a soil temperature of 70-80°F (21-27°C) for optimal germination, which typically takes 5-10 days.
  • Keep the soil consistently moist during the germination period, but avoid waterlogging to prevent seed rot.
  • Thin seedlings to 12-18 inches apart once they have several sets of true leaves to provide enough space for mature growth.

Additional Tips

  • Zinnias thrive in full sun and prefer well-draining, moderately fertile soil. Add compost to the soil before planting to enrich it.
  • Water regularly, especially during dry periods, but avoid getting the foliage wet to reduce the risk of fungal diseases.
  • Apply mulch around the base of the plants to retain moisture, suppress weeds, and maintain an even soil temperature.
  • Deadhead spent flowers regularly to encourage continuous blooming throughout the summer.
  • Fertilize every 4-6 weeks with a balanced, water-soluble fertilizer to promote healthy growth and more vibrant blooms.
