When to Plant Zinnia in Dixie County, FL

Zinnia (Zinnia elegans) is a fast-growing, heat-loving annual that produces bold, dahlia-like blooms from early summer until hard frost. One of the easiest flowers to grow from direct-sown seed, zinnias thrive in hot, dry conditions and are magnets for butterflies and beneficial insects. They make excellent companion plants alongside marigolds in the vegetable garden.

Dixie County, Florida is in USDA Zone 9a. The average last spring frost is March 11 and the first fall frost is November 23, giving you a growing season of approximately 257 days.

Summer highs average 101°F, so Zinnia may need afternoon shade and extra watering during peak heat.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Zinnia root diseases.
