Native to the Mediterranean region, knowing how to grow leeks will provide you with a versatile Allium vegetable that marries exceptionally well with potatoes. Hardy to grow and high in vitamins, leeks make a great garden crop, especially considering their often higher price tag at the grocery store.

They can be used as a milder substitute for onions in both raw or cooked preparations. Their high fiber content can help support a healthy digestive system and the vitamin K they provide contributes to healthy blood and bones.

Different Varieties of Leek

While they all look quite similar, the different varieties of leek available will offer some flexibility in growing times, hardiness, and flavor. A few varieties can even be overwintered which may improve their taste, according to some growers.

A cultivar that can be harvested early as a scallion or left to mature into a full-sized leek, Lincoln Leeks are mildly sweet in flavor and will not take up your garden real-estate for the whole growing season since they reach maturity around 75 days from planting.

Taking a bit longer to mature, but still considered an early-season cultivar, Lancelot Leeks are resistant to bolting, reliable and can be overwintered in certain regions with mild winter weather.

Cold-resistant Musselburgh Leeks grow quite large - up to 15” high with a 3” diameter at maturity. Their stalks remain mild-flavored and tender, especially when overwintered, which make them a popular choice for the home gardener.

How to Harvest Leek

Harvest leeks when they are about 1 inch in diameter by simply pulling them up out of the soil and shaking off the dirt from their fibrous root system. Pull back 1 or two layers of the outermost leaves to clean off the leek and cut the roots down to about ¼ inch. The dark green tops can also be trimmed back for easier storage. Leeks can be stored in the fridge for about a week, or chopped up and either frozen or dehydrated for longer-term storage.
