How to choose leek seeds

Leeks are the backbone of the winter kitchen. From caramelised side dishes to warming winter soups, they offer a delicate, sweet flavour that improves after a frost. Select a mix of early and late-maturing varieties, and you can ensure a continuous supply of fresh stems from October right through to April. Read these FAQs to help you choose the right variety.

Why grow leeks from seed?

Growing leeks from seed offers much better value than buying mature plants and often provides better taste compared to shop-bought vegetables. It also gives you access to a wider range of varieties, ensuring you can harvest fresh, hardy crops for seven of the colder months of the year.

Which leek variety is best for a winter harvest?

The leek variety that’s best for a winter harvest is ‘Musselburgh’, noted for being extremely winter hardy. It’s bred to withstand unpredictable weather and can be harvested fresh from the ground throughout winter.

Which varieties should I grow for a continuous leek harvest?

For a continuous leek harvest that lasts from October through to April, sow a combination of varieties. Start with 'Atal' for your early autumn cropping; it has a milder, spring-onion-like quality perfect for lighter dishes. Follow this with 'Musselburgh' or 'F1 Below Zero' for your main winter crop, as these are extremely hardy and stand well during the coldest months.

Do I need a greenhouse to grow leek seeds?

No, you do not need a greenhouse to grow leek seeds. While you can sow under glass in January for exhibition-sized leeks, you can easily sow seeds directly outdoors in a seedbed between March and April for a reliable general crop.

Can I grow leeks in a small space garden?

Yes, you can successfully grow leeks in a small space. If garden space is limited, sow leek seeds in deep pots or containers. They’re a versatile crop that requires little maintenance once established.
