When to Plant Marigold in Florida

Growing Marigold in Florida: Complete Guide

Marigold (Tagetes patula) is a warm-season crop that needs a head start indoors before Florida's last frost. Most Florida gardeners begin seeds indoors around Thursday, November 20, 2025 and move transplants outside around Thursday, January 15, 2026, after the risk of frost has passed.

Because Florida stretches across 7 USDA hardiness zones (8b, 9a, 9b, 10a, 10b, 11a, 11b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 50 days to maturity, Marigold needs the indoor head start that Florida's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Marigold requires full sun (6-8 hours) and moderate (1 inch/week) moisture. Most of Florida receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
