Shipping Information & Notes
DAYS TO GERMINATION: 7-10 days at 75°F (24°C). When planted outside, soil temperature must be above 60°F (16°C).
SOWING: Direct seed (recommended): After last frost, once soil temperature is above 60°F (16°C), sow seed thinly in rows, barely covering the seeds. Thin when the first true leaves appear. Tall varieties may benefit from some wind protection. Transplant: Sow seed thinly, barely covering, 5-7 weeks before setting out. Keep soil moist until emergence. When the first true leaves appear transplant into larger containers. Harden off and transplant outdoors after the last frost.
