Care
Benary’s Giant Zinnia Care
Plant outdoors after all danger of frost once soil temperatures are above 50°F. Choose a sunny site with well-draining soil and good air circulation. Avoid overcrowding to minimize mildew risk.
Water regularly during establishment, then moderately throughout the season—keep soil moist but not soggy. Avoid overhead watering to reduce disease pressure. Feed monthly with a balanced slow release fertilizer to promote vigorous growth and abundant flowering.
Deadhead or harvest often to encourage reblooming. Pinch once early in the season for stronger branching and longer stems. Protect from high winds once fully flowered, as large blooms can become top-heavy.
