Growing Instructions


Sun Exposure: Full sun.
Soil:  Soil pH of 6.0-6.5. They are moderate feeders and require very deep, rich soil. Add compost and well-rotted manure prior to planting.
Moisture:  Use mulch to conserve moisture and to keep the weeds down. Good soil moisture helps to keep the stems tender and juicy. Water during dry spells.
Planting: Start indoors 8-10 weeks prior to the last frost. Once soil can be worked in the spring, seedlings may be set in a trench about 5 inches deep, filling in enough soil to cover the roots. Gradually fill the trenches in during the season. Planting this way blanches the shaft. 
Spacing:   Plant 9 leeks  per square foot of growing space using Square Foot Gardening Method.  Or plant in rows 24 inches apart.
Sow seeds: Sow seed 1⁄4 inches deep and provide a soil temperature of 24 degrees C with even moisture. 



Harvest in late summer or early fall before frost. The shafts should be 11⁄2 inches-2 inches in diameter. Mulch with straw if frost threatens.


Storing the entire unwashed leeks in the fridge with the plastic bag can keep this ingredient for up to 2 weeks. Otherwise, you can freeze and preserve them for up to 3 months.
