Method note
Start transplants indoors 4-6 weeks before last frost; direct-seed or transplant out only after the last frost (frost exposure bolts spring crops); 6-12 inch spacing in 18-30 inch rows; 1/4-1/2 inch depth; full sun to part shade; pH 6.0-7.5; and the bolting tendency all from this page. Days to maturity vary widely by variety and are omitted.
