First make sure there is no danger of frost. Frost can easily kill bush beans. Bury 4-6 seeds 2 inches deep from each other in rows. Cover each seed with soil and then water them. When you plant bush beans, you want to water them right away.
Make sure the area is clean and there are no weeds growing. Weeds can steal all nutrients from the green beans and this can result in killing of the bush beans plant. Water your bush beans every day. You can also include a layer of mulch to help control the weeds and make sure that the ground is moist.
