Garlic may well be the easiest crop you've never tried. The steps are simple: 1) buy seed bulbs 2) break into cloves 3) plant in rich, loose soil 2 inches (5 cm) deep and 6 inches (15 cm) apart 4) mulch 5) water and 6) wait. Ok, that's over-simplifying a bit, but not by much. This short video offers more info and will get you thinking about working some space for garlic into next year's garden plan.
