Here's your September gardening guide for North America's USDA Plant Hardiness Zones: 3-10. (Did you know that the USDA Hardiness Zones have changed?)

We've left off zones 1–2 (far-north Alaska) and zones 11–13 (small section of the Florida Keys, the Pacific coast between L.A. and Mexico, and Hawaii) since zones 3–10 cover 99 percent or more of the gardeners in the U.S.
