How do I best grow my leeks?

At what depth should I plant leek plants? Some say the deeper the better. And what pH do they like to get white fleshy stalks?

 

Plant leeks when they are 15-20 cm long and the thickness of a pencil. Make the hole 10-15 cm deep. Plant the seedling so that the roots are just resting in the bottom of the hole and leaves just showing above the soil surface. Do not firm in — water in the seedlings and as the soil settles it will fill in the hole and hold the leek plant firmly in the ground. Plant leeks in a soil with a pH of 6-6.5.

Lovely white stems are formed by earthing up (or mounding) around the leeks as they grow — this is not essential, but leeks are certainly much more delicious when grown this way.
