How to Grow Beans (Phaseolus vulgaris) Dependable and easy to grow, beans produce rewarding crops in gardens across the country. Beans grow best in full sun, planted in well-drained and warm soil. While pole beans require trellising, bush beans can grow unsupported. These growing instructions are for common beans (Phaseolus vulgaris). There are several other species of beans, including runner beans, lima beans, cowpeas, and soybeans.
Time of Planting: Direct sow after the soil has reached at least 50 degrees, but preferably when the soil is 60-80 degrees.
Spacing Requirements: Plant the bean seeds ½ inch deep and 2-3 feet apart directly into warm soil, once the danger of frost has passed.
Time to Germination: 8 to 10 days
Special Considerations: You can build bamboo trellises for pole beans before planting the seeds. Garden spacing is the same whether growing for seed or to eat.
Common Pests and Diseases (and how to manage): Common beans can be affected by a number of diseases. Some of these diseases can remain in the soil for several years, so grow your beans in different areas of the garden each year. To prevent the spread of fungal and bacterial diseases among plants, avoid working in your bean patch when the foliage is wet. The best way to get rid of beetles and bugs that might eat the leaves of your plants is to pick them off and toss them into a jar of soapy water.
Harvest (when and how): Beans can be harvested in the snap/green stage, the shelling stage, or the dry stage. Try to harvest beans before the first frost. Some gardeners extend their season by covering their plants with sheets, blankets, or row cover ahead of cold weather.
Snap or green beans are ready for harvest when the pods are still tender, before the seeds start to swell. Shelling beans are ready for harvest after the pod has changed color and the beans have plumped, but before the pods and seeds have dried. Dry beans are ready for harvest when the pods are dry and brittle and the seeds inside are hard.
Eating: Green (snap) beans are best eaten fresh, canned, or frozen. Shelling beans are best eaten fresh and must be removed from their shells before being eaten. Dry beans must be soaked and boiled before eating.
Storing: Beans can be stored dry for months or years. They last in the refrigerator for about a week.
