Leeks, belonging to the Allium family, are a delightful addition to any garden. Not only are they milder and sweeter than onions, but they also efficiently utilize garden space. This guide will take you through the steps of planting, caring for, and harvesting leeks.
Planting Leeks
Leeks thrive in full sun and require deep, fertile, well-drained soil rich in organic matter. The ideal soil pH is neutral to slightly alkaline (6.0-7.0). You can start leeks from seeds indoors about 10-12 weeks before the last frost date. Transplant the seedlings 3-4 weeks before the last frost when daytime temperatures reach 45°F. Leeks can be planted in the ground, raised beds, or deep containers.
How to Plant
Sow seeds in soil blocks or trays with moistened seed starting mix, about ¼ inch deep.
In cell trays, plant two seeds per cell and thin to one after germination.
Keep the soil moist and provide ample light after sprouting.
For planting out:
Enhance the soil with compost if necessary.
Plant leek seedlings deeply using trenching or hilling methods.
Mulch to maintain soil moisture and control weeds.
Growing and Care
Leeks require consistent watering, with about an inch per week being ideal. Use drip irrigation for efficient watering. As they grow, gradually fill in the trench or hill the soil around them to blanch the stems, making them sweeter and longer. Avoid deep cultivation to protect the shallow roots; instead, use mulch and hand-pulling for weed control.

Harvesting Leeks
Leeks are not demanding in terms of harvest time. They can be picked as needed from late summer until the ground freezes. In warmer climates (USDA zone 7 or above), leeks can remain in the ground throughout winter. Harvest young for mildness or let them grow larger for a more robust flavor.
