Growing
Direct sow between late-May to the end of June as long as the soils are warm. If the soil is not warm enough, the seeds will rot. Plant 2-5cm (1-2") deep, 5-8cm (2-3"). Seeds sprout in 8-16 days depending on conditions but can also be started indoors and carefully put out a few weeks later. For a continuous harvest, plant at 3 week intervals.
