Care
Zinnia 'Benary’s Giant White' Care
Plant outdoors after all danger of frost when soil has warmed to at least 50°F. Zinnias thrive in full sun and prefer rich, well-draining soil. Avoid excessive humidity and poor air circulation to minimize mildew risk.
Water regularly during establishment, then deeply but infrequently to keep the soil evenly moist—never soggy. Avoid overhead watering to prevent fungal issues. Feed every 4–6 weeks during the growing season with a balanced slow release fertilizer to encourage continuous flowering.
Deadhead or harvest frequently to stimulate reblooming. Pinching young plants at 6–8" encourages branching and stronger stems. Once mature, the large blooms may benefit from light staking in windy sites.
