How to Sow
Because the small seeds have to be sown quite shallowly, it will be easier to keep seeds moist during germination if sown in trays. Alternatively, sow a few seeds in planting stations at the correct spacing and thin after germination. Sprinkle a little loose soil over the seeds till they are no longer visible and keep moist.
How to Harvest
Start using the leaves as soon as they are big enough to pick, or allow it to form dense upright heads. If you are able to leave some stem behind when harvesting, they may resprout.
