Prepare the beds by amending them with compost and organic material so that you have loose, well-drained soil. Beans grow best in temperatures between 50 to 85°F, in full sun. Planting too early when the weather is wet and cooler than 55°F may cause your bean seeds to rot. Sow your bush beans 1 inch deep and 4 to 6 inches apart, with rows 18 to 24 inches apart. Beans have fragile roots, making transplanting them difficult. Direct sow when the soil is warm enough. Drip watering is better than overhead watering to prevent disease and fungus from setting in. One benefit of growing bush beans is you do not have to worry about crafting a supportive trellis.
If your soil is decent, you will not need to use fertilizer because beans will actually add nitrogen to the soil as they grow. If you feel the need to fertilize, choose one low in nitrogen. (The three numbers on fertilizer are Nitrogen-Phosphorus-Potassium, so make sure the first number is low or 0.) Beans produce nitrogen and will restore nitrogen-deficient soil. Bush beans have many vegetable friends but no real foes, which makes them easy to fit in just about anywhere in your garden.
