Description
DAYS TO GERMINATION: 3-5 days at 80-85oF (27-29oC) SOWING: Transplant (recommended) - Sow into 72-cell flats or preferred seedling container 4 weeks before last frost. Cover seeds. A heat mat will help maintain an accurate temperature. Lower temperatures will result in slower germination: 5-7 days at 70-75oF (21-24oC). Harden-off & transplant out after last frost. Do not allow plants to become root bound & avoid disturbing roots; transplant shock or other stress events may cause double-flowering varieties to produce single blooms for a period following stress. Direct seed - After last frost, sow 1/4" deep. Succession-sow/plant every two weeks for prolonged yields of high-quality stems. Pinching of initial bud or bloom & subsequent deadheading is recommended to encourage strong branching & bloom production. LIGHT PREFERENCE: Sun. PLANT HEIGHT: Varies. No support is necessary. PLANT SPACING: 9-12". HARDINESS ZONES: Annual. HARVEST: Before completely open. Stem is firm from point of cut to just below the bloom. SOIL REQUIREMENTS: Fertile soil rich in organic matter. pH: 6.3-6.8 preferred. Zinnia Oklahoma White Seed 50
