Green Bean
Phaseolus vulgaris
Zones 7–13
Growing
When you are ready to sow, ensure the soil has warmed and is well-drained, aiming for a slightly acidic to neutral pH between 6.0 and 7.0. Since these are annual legumes, they thrive in the heat of the summer but are highly sensitive to cold; even a light frost will kill the plants. Because the flowers are self-pollinating, you can expect pods to develop even if pollinators are sparse, though a sunny spot will certainly help.
Depending on the variety you choose, your garden layout will change. While some beans are climbing vines that require sturdy trellises, the bush varieties you are growing here stay compact and erect, making them perfect for containers or small garden beds without the need for heavy staking. Keep an eye out for different pod types, such as stringless French beans, which lack the tough, fibrous fibers found in older string bean varieties, or wax beans, which feature yellow or white pods.
To get the best flavor, harvest the pods as soon as they reach your desired size. Unlike many other crops, green beans do not continue to ripen once they are picked, so you must harvest them promptly to prevent them from becoming tough. For long-term use, you can freeze the pods after blanching them in boiling water. If you prefer to keep them fresh, store them unwashed in the refrigerator to prevent moisture buildup.
