To cultivate leeks, the soil should be rich in organic matter and have a pH between 6.0 and 7.0. Leeks require consistent moisture, especially during the first few weeks after planting. As the leeks grow, they should be hilled up to blanch the stems and promote a sweeter flavor. Leeks can be harvested when the stems are about 1 inch in diameter, and can be pulled from the ground by grasping the leaves and twisting the base. With proper care and attention, homegrown leeks can be a delicious and rewarding addition to a variety of dishes.
