Leeks are in the same family as onions and garlic, but have a much lighter and sweeter flavor than most of their relatives. They can be grown anywhere in the United States that has a moderately warm summer. These vegetables require very little maintenance or special care once they start to grow. In order to get the best possible leeks, they must be planted in the right conditions.
Choose a spot in your garden that gets full to partial sun.
Till the soil to a depth of 4 inches. Pull out any weed roots that the tiller pulls up.
Dig quarter-inch-deep holes about an inch apart from each other for the seeds. If you're planting multiple rows of seeds, space them 8 to 10 inches apart.
Drop two to three seeds in each hole. Leek seeds generally have a high germination rate, but it's best to plant a couple extra just to be safe.
Sift soil over the seeds to cover them. The fine soil will ensure that seeds have no problem sprouting out of the ground.
Pat the soil down gently and add water. The soil must remain damp at all times.
