Germination Temperature: Optimum soil temperatures 65-85ºF.

Starting Indoors: 4-6 weeks before last frost or 4-6. Sow 2-3 seeds per cell/pot at 1/4" depth. Fertilize the seedlings every 7-10 days with a liquid or water soluble fertilizer, diluted to ¼ of suggested measurement. Transplant a week or two before last frost. Sow in late spring to transplant out for fall crops.

Sowing Outdoors: In spring when soil temperature reaches at least 60ºF. Sow 2-3 seeds every 15-18” apart for small headed varieties, 24-36” for large headed varieties. Thin to the strongest seedling per space. Sow in early summer for fall crops. Germination is slower at lower soil temperatures.
