Garlic that you buy at the grocery store will do, but you may want to take a look at some of the specialty garlic in gardening catalogs or your local garden center. Plant the bulbs in a well-drained location in full sun. If you are concerned about drainage, build a raised bed. Break the heads into individual cloves and plant the cloves six inches apart so that the tips are showing. Water well and apply a thick mulch after the first freeze if the ground freezes in your area
Planting with Peanuts
Use the "packing peanuts" you get in packages as a base for repotting plants. They provide drainage and are lightweight. Crumble the peanuts and place them in the bottom of your pot, put in the potting soil of your choice and plant as usual.
