Cultivation: Prepare fertile, well-drained soil. Sow seeds in spring after last frost to early summer or late summer/early fall. Keep soil moist. Fertilize as needed. Optimum growing temperatures are in the 60s°F. Exposure to frost or prolonged temperatures below 50°F may result in bolting. Mulch fall crops to avoid premature bolting. Most vegetables leave having purple color is called “anthocyan” which is generally developed by lower temperature. Growing temperatures 50-60°F should be adequate to develop “anthocyan” after the seeds have germinated. We cannot tell exactly how long exposure should be under low temperatures. The grower should trial different methods and observe how the plant reacts.
