Knowing how and when to fertilize leeks helps you get a fantastic harvest of long and sweet stems. Leeks are simple to grow and have a milder taste than onions, they are versatile enough to be used in all manner of dishes.
While often regarded as a winter crop, growing different varieties of leeks can provide harvests from summer through to spring. Whatever type of leeks you grow, from early varieties to harvest in summer to late types that can overwinter in the ground to be lifted the following spring, they all benefit from being fertilized during the growing season.
