Cool Season GardeningFall gardening
Grace your dinner table with an easy-to-grow, elegant onion cousin: the leek. Sweet and mild,leeksare gentle on the digestive system and play the role of onion in dishes, only toned down. Unlike onions, leeks dont produce bulbs but stash their flavor in thick, juicy stems that look similar to giant scallions. Leafy stems are pretty, and growing leeks doesnt require much room in the garden.
In the supermarket, leeks cost a premium; harvested from the garden, theyre a bargain. Leeks are most famous for leek and potato soup, but theyre also good steamed like asparagus, oven-roasted, chopped in quiche, or wrapped in ham and baked (perhaps with a little cheese on top).
Frost-tolerant leeks thrive in cool weather. Inzones 7 and warmer, plants can overwinter in the ground, making them perfect for fall planting. In northerly zones, tuck plants into beds in early spring, as soon as soil can be worked.
Plant leeks during the cool weather of early spring and fall. They grow well in raised beds, containers, and in-ground gardens.
Space leeks 6 inches apart in an area that gets 6 or more hours of sun daily and has nutrient-rich, well-drained soil.
Improve native soil by mixing in several inches of aged compost or other rich organic matter.
Leeks arent fussy, but they do require moist soil, so check soil moisture often and use a soaker hose if necessary.
One week after planting, begin regularly feeding with a water-soluble plant food.
Harvest leeks at any time once they are large enough to eat.
Plant leeks in a sunny spot in soil that is fertile and well-drained. Leeks thrive in traditional garden beds, raised beds, or even in tall containers, so choose whatever works best for you. Space leeks 6 inches apart when planting.
Leeks need two things to thrive: lots of nitrogen and consistent soil moisture. If possible, add compost to the leek bed the season prior to planting. To improve the soil if you havent thought that far ahead, mix in a few inches ofMiracle-Gro® Performance Organics® All Purpose In-Ground Soilwith your native soil. Or, if planting in raised beds or containers, be sure to fill them with the right type of soil for that growing environment, such asMiracle-Gro® Performance Organics® Raised Bed Mixfor raised bed gardens andMiracle-Gro® Performance Organics® All Purpose Container Mixfor pots.
To produce a succulent white stem, leeks must be blanched in other words, covered or hidden from the sun. To do this, plant leeks into deep holes. (Deeper planting yields a more drought-resistant plant, too.) Create a narrow trench 6 to 8 inches deep, then tuck seedlings into the trench, adding soil back so it comes up to the base of the first green leaf. Water well.
After planting, mulch the bed with straw or some other organic material to help soil retain moisture. Feed newly planted leeks withMiracle-Gro® Performance Organics® Edibles Plant Nutritionevery seven days. Water leeks as needed until plants are established. After that, plants require an inch of water a week, either through rainfall or irrigation. Inconsistent moisture yields tough stems.
As leeks grow, mound the soil from the trench around stems, beginning when stems are 1 inch thick.
Soil that tumbles into leaf folds can wind up trapped between skin layers in the stem. To keep this from happening you can slip a section of paper tube, such as from toilet tissue or paper towels, over the plants while they are still young as early as planting time. The tube will rot over the growing season, but will help prevent soil from getting into leaf bases during early growth.
On young plants, slugs can be devastating. Gather them at night, set traps, or use biological control. If there is a lot of rain in winter or early spring, leaf rot can set in. Rot shows as white spots on leaf tips that eventually shrivel. At this point there is not much you can do except pull the rotted plants and thin the planting to increase air circulation.
In summer, orange pustules on leaves indicate leek rust, which is worse in wet growing seasons. Remove affected foliage; later maturing foliage will be healthy.
Because they are so cold-hardy, you could find that you still have leeks left in the garden that have made it though the winter, planted many months before. At this point, dig them because they will throw up a bloom stalk that ruins the fleshy texture of the stem.
You can start pulling leeks from the ground just about anytime. Typically, youd let them get least 1 inch or larger in diameter for the big white stems, but you can dig young ones to eat like scallions. If the soil is moist, they may just pull right out of the ground. If they resist, use a spading fork to loosen soil and then gently pull leeks by grabbing them at their base.
Inzones 7 and warmer, you should be able to harvest leeks all winter long.
In colder areas, extend the harvest season by mulching deeply around plants (up to 1 foot deep) before a hard freeze. You could continue harvesting leeks until they are locked frozen into the ground, but dont let that happen. Dig them first and store.
Wash the stems thoroughly to remove soil and grit that may have collected between the leaves.
For short-term storage (up to one week), tuck stems into an airtight plastic bag and place in the refrigerator crisper. For longer storage in coldest zones, dig leeks with roots attached. Cut leaves back until just an inch of green remains on each leaf. Place stems in a box (root side down) and pack with sawdust, clean sand, or vermiculite. Keep the packing moist and store in a cool place. Stems will keep up to 8 weeks.
To freeze leeks, wash, slice, and blanch for 1 minute in boiling water. Drain, drip dry, and toss into plastic freezer bags. Add the frozen leeks to soups, stews, and other dishes.

Bury the plants up to the point where the foliage arises from the stem, but not so deep that soil gets into the folds between the leaves.
These leeks could stand to have the soil mounded up around their stems more deeply for better blanching.
Even though our biodegradable pot directions indicate planting the whole pot, in the case of leeks, you need to remove the plant from the pot and very gently coax the clump of seedlings apart so that you can plant each leek seedling separately.
Ideally, leek stems will be long and white at harvest time. The white part is where the stem was blanched underground, hidden from sunlight.

Should I just plant the pot of leeks like I do with other Bonnie plants?
No, this is an exception to our plant-the-pot rule. Our pots are sown thickly with leek seedlings, which means you get a lot in one pot. Gently separate the seedlings to plant.
Yes, you can grow them in containers. Use a container about 18 inches deep and fill it only about 2/3 full of soil to begin with. Continue filling as the stems grow so that they will blanch. Make sure to water and fertilize regularly. Use a liquid plant food when you water to encourage fast growth that will result in tender stems.
American Flag, the heirloom variety that we offer, is one of the most cold hardy. You will also run into what is called a summer leek which is intended to plant in spring and harvest before cold weather. However, American flag will over winter in Zones 7 and warmer, easily tolerating temperature in the teens.
You can strip away the leaves and eat what white part of the stems is left below the leaves. The green portions are actually edible, but they wont be as tender.
