I had a head of garlic lost in the cupboard that was starting to give off shoots, so I just broke up the head, loosened the soil to about 3" deep and shoved each clove in the soil with the sprout side up, then loosley covered them with soil and watered them in. Bing, bango, bongo...15 minutes and I was done. I've done this before and got decent heads of garlic which are delicious because they are so fresh. Give it a shot in a flower bed or even a planter box somewhere. Allow about 6" between each clove when planting so the bulb has room to grow.
