Marigolds are one of the most beloved annual flowers in the world — adored by home gardeners, cut-flower growers, and nurseries alike for their reliability, color power, and versatility. Whether you’re planting them from seed, using them as companion plants for pest control, or filling flowerbeds with bold sunshine-yellow blooms, marigolds deliver results every time.

At Garden Starts Nursery and TrailingPetunia.com, we grow marigolds from seed ourselves — and we also offer starter plants for resale in 4" pots to home gardeners, landscapers, and market growers. So this guide is not textbook theory — it’s hands-on growing knowledge.
