Choose a garden area that gets several hours of direct sunlight. To prepare for planting, work in some compost or soil building conditioner and a general-purpose fertilizer for acid-loving plants like blueberries and rhododendrons.
Leeks should be placed 6″ apart. Plant them deep, just the tip of the newest leaf needs to be visible.
During the growing season, water plants when the soil is dry up to your first knuckle and apply a high nitrogen fertilizer regularly. Stop applying fertilizer when you can tell the plants are starting to bulb.
You can begin harvesting leeks as needed after just 30 days.
