Apply a seedling-starter fertilizer such as Evolve Seedling once the second set of true leaves has appeared, and then alternate between the kelp and seedling starter until transplant.
Planting out: Plant seedlings in a trench 6 inches wide and 6 inches deep. When plants reach 6 to 8 inches tall, gradually hoe fine soil from the sides of the trench to fill the space. Keep doing this over the next 3 weeks adding an inch of soil around the leek. Always keep the soil level just below the point where the leaves diverge form the stems.
Notes: Leeks must be started indoors in February or March to produce a summer crop.
