Oklahoma Formula Mix Improved Zinnia Seed

This improved mix is an essential component of any cut-flower offering. Prolific, double and semidouble blooms are easy to use in bouquets due to their smaller size. The 1 1/2–2 1/2″ blooms hold up well to handling compared to larger blooms which can snap at the stem due to the weight of the larger flower heads. Cut-and-come-again flower, yielding multiple cuts over the season.Ht. 30–40″. Avg. Packet: 45 seeds

DAYS TO GERMINATION:3-5 days at 80-85°F (27-29°C)

SOWING:Transplant (recommended) – Sow into 72-cell flats, or preferred seedling container, 4 weeks before season grow. Cover seeds. A heat mat will help maintain an accurate temperature. Lower temperatures will result in slower germination: 5-7 days at 70-75°F (21-24°C). Harden off and transplant out after last frost. Do not allow plants to become root bound and 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 2 weeks for prolonged yields of high-quality stems. Pinching of initial bud or bloom and subsequent deadheading is recommended to encourage strong branching and bloom production.
