About this plant
Leeks develop excellent flower heads if they are allowed a second year of growth. The heads are like the rest of the alliums: large, tight balls, full of little, lilac flowers, held on long, rounded stalks. Leek foliage is also quite ornamental in its own right. The upright, blue-grey, strappy leaves look rather like those of irises. It is always interesting to ponder vegetables as ornamentals and to consider their use outside the vegetable garden.

Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
