Zinnia Seeds,
Queen Lime Red

Plant Queen Lime Red zinnia seeds after the last frost when soil temperatures are consistently warm, typically in late spring. In USDA hardiness zones 3-10, these seeds can be direct sown outdoors or started indoors 4 weeks prior to the last frost for earlier blooms. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Sow seeds directly 1/4 inch deep in a sunny location. Space the plants 9-12 inches apart to ensure good air circulation, minimizing the risk of mildew. If starting indoors, plant seeds in trays and keep them moist until germination, which takes about 4-6 days. Transplant seedlings outside once temperatures are warm​. Use biodegradable pots or other means to minimize root disturbance when transplanting​.

These zinnias need at least 6-8 hours of sunlight daily. Water moderately, making sure the soil dries between watering sessions to prevent root rot. Occasional fertilization with a balanced fertilizer can improve flower production.

• 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.
