Care essentials
Light
Plant zinnias in full sun — 6 or more hours of direct sunlight daily — for maximum flowering; in NE Florida's intense summer heat, good air circulation around plants is equally important to reduce the powdery mildew that commonly affects zinnias in humid conditions.
Water
Water zinnias at the soil level, keeping foliage dry to minimize powdery mildew; maintain moderate, consistent moisture and allow the top inch of soil to dry between waterings. In NE Florida's rainy season, reduce supplemental irrigation and ensure good drainage to prevent root rot.
Soil & Fertilizer
Zinnias thrive in well-drained sandy or loamy soil of average fertility; in NE Florida, direct-sow seeds or transplant after the last frost (typically February) for a spring-to-fall display. Apply a balanced slow-release fertilizer at planting and deadhead regularly to extend the long blooming season.
