Zinnia Seeds,
Queen Lime Blush

Plant Queen Lime Blush zinnia seeds after the last frost when soil temperatures are consistently warm, at least around 70 F. They should be started outdoors in late spring, after the last frost. For earlier blooms, start seeds indoors 4 weeks before the last frost and transplant them once the weather warms up. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Directly sow seeds 1/4 inch deep in a sunny location with well-draining soil. Space plants 9-12 inches apart for adequate airflow, which helps prevent mildew. If starting indoors, use trays and lightly cover seeds, as they need light for germination. Use biodegradable pots or other means to minimize root disturbance when transplanting​.

These zinnias require full sun 6-8 hours daily and moderate watering. Allow the soil to dry between waterings to avoid root issues. Applying compost or a balanced fertilizer will improve blooms.

• 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.
