Leeks are a hardy, mild-flavored member of the onion family. They tolerate cold and store well in the garden, which makes them a good choice for extended harvests. This guide covers planting, care, and harvest.
Start Seed or Buy Transplants
Start seed indoors about 10 to 12 weeks before transplanting. Leeks need a long season, so starting early helps. Transplants are a convenient option.
Site and Soil
Choose full sun and loose, well-drained soil with plenty of organic matter. Avoid waterlogged sites.
Planting
Dig trenches about six inches deep and set transplants in them. Drop each plant into the trench and fill it with water rather than soil, which helps blanch the stems. Space plants about six inches apart.
Care
- Keep the bed weeded, since leeks compete poorly with weeds.
- Water regularly, especially in dry weather.
- Feed with a balanced fertilizer or side-dress with compost during the season.
Harvest
Harvest leeks when stems reach the desired thickness, usually from late summer into winter. Leeks tolerate frost, and many can stay in the ground until needed.
