Double Zinnias Seeds Growing Guide
• Sowing: Sow seeds 1/4" deep in moist soil after the last frost, or start indoors 4–6 weeks earlier.
• Location: Full sun.
• Soil: Well-drained, fertile soil with moderate organic matter.
• Water: Keep soil evenly moist during germination; once established, water regularly but avoid overwatering.
• Care: Heat-loving annual; pinch young plants to encourage branching and deadhead spent blooms regularly to promote continuous flowering and full, double-petaled blooms throughout the season. 🌸
