Sow shallowly, about ⅛–¼ inch deep, and keep the seedbed evenly moist. Germination commonly takes 4–10 days under suitable conditions. Very warm soil can inhibit germination; start summer sowings in a cooler location rather than relying on heat tolerance at the seed stage.\u003c\/p\u003e\u003cp\u003eThin or transplant to approximately 12 inches apart, providing extra room where outer leaves become crowded.
