How do I sow summer leeks under cover?

To sow summer leeks successfully under cover, it's important to choose a deep container to allow the roots to develop properly. Use individual cups or trays filled with light, well-drained potting soil. Sow the seeds about 1 cm deep and space them a few centimetres apart to avoid them touching.

Sowing under cover is generally done in spring, when frosts are no longer a concern. Be sure to maintain a constant temperature of between 15 and 20°C to encourage germination. Water regularly but sparingly to avoid excess moisture that could rot the seeds.

Once the leek plants are about ten centimetres tall, you can transplant them into the ground, taking care to space them about 10 cm apart. Make sure you water them well, especially in dry periods, to encourage their growth.

How to plant summer leeks?

To plant summer leeks in the ground, it is essential to choose a sunny spot with well-drained soil rich in organic matter. Before planting, we recommend loosening the soil by spading and removing weeds. Ideally, leeks should be planted in rows about 20 cm apart, making holes about 10 cm deep.

It is important to ensure that the plants are straight when planted and to pack the soil well around the roots to avoid air pockets. Afterwards, it's essential to water the plants regularly, but avoid excess water, which could encourage root rot.

If you decide to transplant leek plants bought in cups, it is recommended that you do so in early spring. Make sure you leave space between the plants so they can develop properly. By following these simple tips, you'll be able to enjoy delicious summer leeks in your garden, without the need for chemical fertilisers.

How do I harvest summer leeks?

Summer leeks can be harvested from August to November. To harvest them, simply pull gently on the plant, holding it at the base. It's best to harvest leeks as and when you need them, so that they retain all their flavour and freshness. Leeks can be stored for up to two weeks in a cool, dry place. It is best to store them in a dark place, away from light, to prevent them turning green. To prolong their shelf life, you can also freeze them after washing, blanching and slicing.
