“To produce a succulent white stem, leeks must be blanched — in other words, covered or hidden from the sun. To do this, plant leeks into deep holes. (Deeper planting yields a more drought-resistant plant, too.) Create a narrow trench 6 to 8 inches deep, then tuck seedlings into the trench, adding soil back so it comes up to the base of the first green leaf. Water well.” (Source)


General: Cover bed with straw and other organic material to retain soil moisture. “Leeks, on the other hand, should be hilled once a month or so by hoeing soil up around their stems, which results in a much bigger harvest. They can be harvested whenever you wish, washed and stored near freezing for many months.” (Source)


Pests: Slugs, can devastate the plant
