If you want to grow really awesome leeks this is the way to do it. Because you typically won’t find them (or anything else if you’re a northern gardener) in nurseries it’s important to learn how to do it yourself. 

Start these inside in early summer. Mine were started on June 11th. You’ll want to plant them in a container that’s deep as the picture shows. If you start them in something that’s too short, you wont’ be able to do the next step. It’s now time to plant them outside. All you do is pull the entire soil block out of the metal container and begin to separate into individual leeks. Then, and this is the important part, drop them into a hole thats 6-8 inches deep. A small amount of leek will be above the soil. At this point, don’t fill the holes with soil. Water in immediately. After a weeks time your leeks will be fully covered naturally with soil. 

When it’s time to harvest you’ll pull your leeks out to discover a white shank that’s 6-8 inches long instead of the normal 2-3 inch leeks you buy at the grocery store. It makes a huge difference.
