Setup, Compatibility & Care
Sowing: Sow seeds indoors or directly outdoors after the last frost. For a winter harvest, aim for sowing in late spring to early summer. Leeks prefer a sunny location with well-drained soil.
Soil Preparation: Ensure the soil is rich in organic matter. Loosen the soil deeply to allow for the long root development typical of leeks. A soil pH of 6.0-7.0 is ideal.
Planting: If starting indoors, transplant seedlings into the garden when they are about pencil-thick. Space plants 6-8 inches apart in rows that are 18-24 inches apart. For container growing, use pots at least 12 inches deep.
Care: Water regularly, especially during dry spells, to encourage continuous growth. As the leeks grow, 'earth up' the soil around the base of the stems to blanch the white shafts. This process also provides support. Protect young plants from pests. For winter harvest, ensure plants are well-established before the coldest weather arrives. In regions with very harsh winters, consider adding a layer of mulch or row covers for extra insulation.
