Whether you want lima, snap, wax or butter beans, growing your own beans in a backyard vegetable garden can be a rewarding hobby. If you haven't grown beans before, don't worry, because the planting process is easy and the beans take care of themselves. To get your plants off to a good start, however, you'll need to know how to grow bean plant seeds. After your beans are established, the plants will do all the work. All you have to do is harvest as much as possible.
Work the soil in your garden bed with a shovel to loosen it six to eight inches deep before adding a 3-to-4-inch layer of garden soil or compost over the bed. Turn the soil to mix the compost in. Test your soil's pH if desired. Most beans prefer a pH of 6.0 to 6.6.
Sprinkle a low-nitrogen granule fertilizer around the garden bed following the packaging directions for quantity based on the size of your garden area. Work the fertilizer into the upper inch or two of the soil so it won't wash away.
Drag a shallow trench with your hoe in a line down the length of your row two inches deep. If you are growing pole beans, set up a nylon mesh or wire trellis system along your row. No trellis is needed for bush varieties.
Plant your seeds into the trench by placing pole beans 6 to 10 inches apart down the row and bush beans set 3 to 6 inches apart. Cover over the seeds lightly without pressing down on the soil.
Water the seeds to wet the soil along the row evenly without washing out the row. Be sure to continue to water the row as often as needed to keep it damp as the seeds germinate. Water regularly once or twice a week as the plants grow.
Train pole beans to the trellis after they reach 4 to 6 inches tall by moving any vines as needed to hold onto the trellis. Keep working the bean plants up the trellis weekly as they get taller. Use plant ties when needed to help loosely hold the plants to the trellis.
