SOWING: Transplant - Sow into 128-cell flats 6-8 weeks before planting outdoors or into a covered structure. Cover seeds very lightly. Bottom water or mist to avoid displacing seeds and soil. Harden-off and transplant outdoors after danger of frost has passed, or transplant directly into a covered structure. Direct seed - Sow in early spring when soil is cool and a light frost is still possible, or late autumn. Surface-sow and keep soil evenly moist until seedlings emerge. Pinching plants is not necessary nor beneficial. Iceland poppies perform best in cooler conditions – below 70°F. Bloom production and quality declines as temperatures rise.
