What to Plant in May USA
On this page
What to plant in May in the USA depends entirely on your zone — this page answers it for every band. May is the main planting-out month across most of the USA. Transplant tomatoes, peppers and eggplant after your last frost, direct sow beans, corn and squash once soil reaches 60-70°F, and keep succession sowing salad.

May garden jobs
- Check soil temperature before sowing beans, corn and cucurbits.
- Water new transplants daily until established.
- Thin direct-sown rows — crowded roots never size up.
- Install stakes and cages now, before plants are large enough to damage.
- Start scouting for pests weekly rather than reacting to damage.
Common May mistakes
- Sowing squash and corn into 55°F soil, where seed rots instead of germinating.
- Planting the whole bean crop at once instead of succession sowing.
- Leaving tomato cages until the plants are already sprawling.
- Watering shallowly and often, which trains roots to stay near the surface.

Frequently Asked Questions
What soil temperature do beans need?
At least 60°F. Below that, bean seed rots in the ground rather than germinating, which is the single most common May failure.
Can I still start seeds in May?
Yes — direct sow beans, corn, squash and cucumbers, and start fall brassicas indoors late in the month for a fall crop.
How often should I water new transplants?
Daily for the first week or two, then deeply and less often to encourage deep rooting.
