Sow a generous amount of seeds into each cell of a seed tray about 10 - 12 weeks prior to your region's last frost and maintain at about 70 -75F or 23C for 2 -3 weeks. Zone 7 and above can also sow this in summer to yield year round harvests. Take care not to cover seeds too much with soil as they need light to germinate. Germination rates for this plant are low so as soon as you have a shoot thin to one plant per cell. Seedlings can take a cooler environment now. Plant out about 2 weeks before you think you will get your last frost about 6 to 8 inches (15 to 20 cm) apart. When shoulders appear, mound over the soil or apply mulch to prevent greening.
