For a leek, should the top be clipped, where the plant is blooming, for the plant to be harvested?
Leeks are an excellent addition to any vegetable garden with their beautiful dark blue-green leaves and are one of the most ornamental of all of the onions. They are biennials, which means they need a dormant period to complete their life cycle and in the second year they produce flowers and seeds. Typically they are more tender in their first year, although they can be eaten once they flower but may be tough and bitter. Cutting off the blooms may stop the leeks from “bolting” to seed so quickly, tricking them in to thinking that they aren’t “mature” yet, but it doesn’t stop the plant from completing its life cycle. The best thing to do is to eat them when they are young. The flowers are great in an arrangement and dry quite well.
