Growing Garlic in Grand Rapids

Grand Rapids's Zone 6a location in western Michigan benefits from Lake Michigan's moderating influence — the lake delays both spring warming and fall cooling, giving a frost-free window of about 160 days. The same conditions that make the region famous for apple and cherry orchards support productive vegetable gardens. Start warm-season crops indoors in early April for transplanting in early May, and use the lake-moderated fall for extended cool-season harvests.

In Grand Rapids (last frost around May 5), garlic can go out around December — approximately 20 weeks before the last expected frost, making it an early-season opportunity.
