As soon as the soil can be worked, leeks can be planted because they are incredibly resilient and forgiving.
In early to mid-spring, sow sparingly directly in drills with the goal of producing pencil-thick, approximately 8-inch-tall plants that can be transplanted to their final location.
Can be transplanted for an earlier crop after being planted in trays under protection.
When pencil size, which is in June or July, carefully lift and remove 1/3 of the roots and the top third of the foliage.
Plant in pre-made, sunny, 8-inch-between-plant holes that are 4-6 inches deep.
