Growing leek for its health benefits

To grow good leek, you must have full sun exposure but not too hot, and cool, rich, deep, well-drained soil.

Good to know:

  • Leek easily drains the soil of its nutrients, so you must let it rest and wait 2 or 3 years before planting leek in the same spot again.
  • To avoid bolting, remember to water your leek regularly and keep the soil free of weeds.

Watch out for small bugs!

The base of the stem is sometimes attacked by onion maggot fly larvae, which leads to their rotting.

Leaves can dry up and die due to allium leaf-mining flies which dig tunnels in the leaves. White rot is the cause of leek yellowing and dying off.

Finally, rust can form oranges spots on the lower part of leaves.

Leek can be eaten steamed or boiled. Fried, it is a delicious side dish to fish and crabs. Leek can even be pickled for those bittersweet fans!
