Product Details

Leeks' mild but rich onion flavor and cold tolerance make them a favorite in home kitchens and gardens. This onion relative has compact stems that thicken but do not form bulbs like onions. 'King Richard' produces extra long white stems early. Enjoy fresh, grilled, sautéed, and added to soups and stews. Cold tolerant to 20°F and can be left in the garden for an extended harvest.

Sowing Info

When to Sow Outside: 2 to 4 weeks before your average last frost date for late summer harvest, late spring for fall harvest, and in Mild Climates, late summer for the following spring harvest. Soil temperature should be at least 40°F, ideally 60°–85°F.

Growing Info

Harvesting: Harvest leeks when tops are 15"–18" tall, and shanks are at least 1" in diameter. Use a garden fork to gently lift and loosen soil under the leeks, and then pull them up by hand. Leeks tolerate temperatures as low as 20°F, and can therefore be harvested even after a few freezes, which enhances flavor.

    I have grown these leeks for 3 years now in Denver (6a). I love that I can leave them in the ground until November-December and get that extra growing time after frost. I start with the winter sowing method in February and transplant in April/May. They are hardy, delicious, and I have had no issues with bugs. I plan to grow these every year!

    I presume that most gardeners plant seeds; I, on the other hand, bury them. These leeks did sprout but something I did didn't work out - they are spindly sort of things. I will try again next year.
