I planted these underneath the cucumber trellis (formerly known as an old, abandoned piece of playground equipment) so that I can throw a blanket over it on a light-frost night, thereby prolonging the season. But the garlic will stay in all winter. It's how garlic grows best.
If you've done your soil amending well, you should still see some of these fellows around when you dig to plant the garlic. Their presence means your soil is still worth their efforts!
I'll leave you with a few links to surf as you consider growing your own garlic...a promise to yourself that you'll pick up this gardening thing again next year!
And if you prefer, a video link as well:
