Step by step

  1. Buy seed garlic from a garden center or seed company. Grocery-store garlic is often a variety that doesn't suit Northwest winters.
  2. Loosen the soil and mix in an inch or two of compost.
  3. Break bulbs into cloves and plant them Oct 1 – Nov 15, 2 inches deep, pointed end up, 6 inches apart.
  4. Cover the bed with a few inches of straw or leaves for winter. Pull weeds in spring and stop watering in early summer when the leaves start to brown.
  5. Harvest: Dig in early summer when the lower third of the leaves are brown. Cure in a shady, airy spot for three weeks.
