Leeks grow best in well-drained, well-fertilized soil with a pH over 6.2. They should receive full sun to partial shade and protection from very hot temperatures. While you can allow your leek patch to self-seed from year to year, you might get higher yields if you intercept the seed and direct the planting yourself.
What do you plant after leeks?
Strawberries seem to enjoy living next to leeks, and the strong odor of the leeks repels many pests of the berries. Other leek plant companions might be cabbage, tomatoes, beets, and lettuce. The leafy vegetables, especially, seem to benefit from the strong scent of plants in the Allium family.
