Bush beans grow best in well drained, organic material rich soil. They need full sun to produce best. Before you start planting bush beans, you should consider inoculating the soil with bean inoculant, which will have bacteria that help the bean plant produce better. Your bush beans will still produce if you do not add bean inoculants to the soil, but it will help you get a bigger crop from your bush beans. Plant bush bean seeds about 1 1/2 inches deep and 3 inches apart after the danger of frost has past. If you are planting more than one row of bush beans, the rows should be 18 to 24 inches apart. You can expect the bush beans to germinate in about one to two weeks. If you would like a continuous harvest of bush beans through the season, plant new bush bean seeds about once every two weeks.
Once bush beans have started growing, they need little care. Make sure that they get at least 2-3 inches of water, either from rainwater or a watering system, a week. If you would like, you can add compost or fertilizer after the bush beans have sprouted, but if you started out with organic rich soil they do not need it.
