Zones 7a and 7b share the same average frost dates, so this page covers both.
Method: Direct sow: Direct-sow outside. It doesn't transplant well, or doesn't need the extra time indoors.

Bush beans are about as low-effort as vegetable gardening gets: direct-sow the seed after your last frost, skip the trellis entirely, and harvest in under two months. They're a good crop to fill a bed with while slower plants like peppers and tomatoes are still getting established.
How bush beans fit zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Bush beans need about 55 days from sowing to first harvest.

Good companions
- Sweet Corn: The classic 'three sisters' pairing. WSU Extension confirms the real mechanism: corn stalks give beans something to climb, beans fix nitrogen the corn uses, and squash (the third sister) shades the soil to suppress weeds.
- Cucumber: Beans fix nitrogen that heavy-feeding cucumbers use.
