Leeks

Leek plantsLeeks are related to onions, but do not develop a bulb. Leeks look like overgrown green onions, with a long, cylindrical white shaft. The leaves are thick, flat and folded. Plants grow two to three feet tall, and can have a width of two inches. Leeks require a much longer growing season than onions, making it more challenging for them to grow to peak quality and maturity in Kansas. Leeks require a long, cool growing season, which means that in most cases, choosing fast-maturing varieties will be best. For spring-planted leeks, look for varieties that are early maturing and heat tolerant. For leeks planted in the late summer to fall, look for varieties that are early maturing and cold tolerant. Fall-planted leeks that will be overwintered for a spring crop can be later maturing and should be selected for overwintering quality and bolt-resistance.
