Zinnia Benary’s Giants Mix (25 seeds)
The premium tall, back of the border zinnia.
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 last frost. Cover seeds. A heat mat will help maintain an accurate temperature. Lower temperatures will result in slower germination: 5-7 days at 70-75°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 two 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.
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.
USES: Taller varieties make excellent cut flowers. Beds, borders, and mass plantings.
SCIENTIFIC NAME: Zinnia spp.
