About Leek
Botanically, Allium ampeloprasum is a moderate-growing edible plant in the Amaryllidaceae family. It reaches around 50 cm tall at maturity.
Where to grow Leek
Leek suits cool-temperate and warm-temperate climates and grows best in full sun. It is frost hardy and shrugs off cold winters.
Soil & planting
Leek does best in free-draining and loamy soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Leek does best with regular, moderate watering. Feed regularly through the growing season for the best crop. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Tip-prune Leek in spring to maintain a dense, shapely habit. Expect a moderate maintenance care workload once it is established.
Using Leek in the garden
Leek earns its place for edible harvests.
Companion planting & design
For easier irrigation and care, group Leek with species that also favour regular, moderate watering and cool-temperate climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
Good to know
Note that it is toxic to cats and dogs, so site it away from pets that chew.
