How to Sow
Leek seeds germinate easily provided they are not planted too deeply, so sow thinly to limit the need for thinning when planting direct. Cover with fine soil or potting medium to a maximum depth of 5mm and keep moist. Germination is faster at warmer temperatures, but soil temperatures of 5 degrees are not too cold.
How to Harvest
Leave leeks to grow as nature intended, or else heap mulch around the stems to blanch them for more white flesh. As soon as they look big enough to eat – they are!
