Just do it. Don’t argue with Uncle Peter. (And Susan, this means you.) Go to your local farmers’ market and buy maybe 10 garlic bulbs. Never mind what kind; just buy them, and separate them into cloves. Then find a bit of empty ground that gets sun and plant them; blunt end down, 2” deep, 6” apart.
If all you have is lawn, then lay newspaper down, 6 sheets thick (trying saying that fast), wet it, and cover it with 3” of potting soil from the garden center. Never mind what kind, just do it. Then plant the garlic cloves in that, before the ground freezes.
What happens is, the wet newspaper provides a welcome mat to earthworms, who will come in to eat, aerate, and fertilize the sod, and then have babies. Each garlic clove, meanwhile, will grow into a new bulb next summer, ready for eating after it’s “cured.”
Use organic garlic in all manner of dishes because it brings food alive, is healthful, and doesn’t cause garlic breath (who started that rumor? Jeez.)
Wasn’t that easy?
