Growing leeks in home gardens

A quick guide to leeks

  • Most leeks require a long growing season of about 120 to 150 days.
  • Start seeds indoors and transplant in early spring.
  • Hill the plants to produce a longer white shaft, or plant in a furrow and fill it in.
  • Leeks have shallow root systems and need plentiful watering.
  • Leeks are tolerant of cold, so you can delay harvest until after the first frosts.

Easy-to-grow gourmet vegetable 

Harvested green leeks with white shafts

Leeks (Allium ampeloprasum var. porrum) are a gourmet vegetable that you can grow easily in Minnesota. They have a mild onion flavor. You may eat them in soups, as well as raw, braised or in casseroles or quiche. You can eat both the green leaves and the white shaft.

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.
