How to plant garlic from start from finish .
Plant garlic cloves 1 to 2 inches deep in warm climates or 3 to 4 inches deep farther north. Place the flat, rooting plate down into the soil so the pointy end of the clove sticks up. For fall plantings, add a 4- to 6-inch layer of weed-free mulch. Grass clippings, leaves or straw work well.
