If you don’t know what USDA Plant Hardiness Zone you live in, check the map here to find out. 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.
- Harden off, and then set out transplants of melons, tomatoes, peppers, cucumbers, eggplant, and squash.
- For a continuous crop of lettuce, radishes, and spinach, sow more seeds midmonth.
- Fertilize and water any potted vegetables regularly.
- Enjoy asparagus right in the garden—even uncooked, it’s delicious.
- Plant tender fuchsias, begonias, dahlias, and asters.
