Leeks

1 gram packet about 240–360 seeds, ¹⁄₁₆ oz packet ~400–600 seeds; 1 oz, 6,400–9,600.

Culture: Start indoors with onions and transplant out in spring almost as soon as the ground can be worked. Set 6–12" apart in trenches or well-dug beds with generous quantities of organic matter. Avoid transplanting next to grass strips; slugs love to dine on tiny allium seedlings. Irrigate seedlings whenever the topsoil dries out.

Summer leeks have tall shanks above ground and should be harvested before severe frosts. Hardier leeks have broader, shorter shanks and will hold till November. Leeks brought into the root cellar will survive almost all winter if heeled into soil. Leek seed is short-lived. Retest 1-year-old seed before using, and discard anything older.
