Plant leeks in early spring and again in midsummer for fall and winter use. Long-growing leeks need a rich fertile soil, so add lots of compost or aged manure before planting, and fertilize several times over the growing season. Weed leeks carefully when young, and mulch to conserve soil moisture.
HARVEST AND USE
Harvest as slim babies to steam whole or quickly grill. Let some leeks mature to full size and dig as needed with a garden fork. Mature leeks store well in the ground during the winter months. Use in cooking like sweet onions, or as a tasty vegetable side dish.
