Shallow cultivation and hand-pulling are the preferred methods to prevent root damage. Once beans begin to reach the picking stage, harvesting continues on a daily basis for days or even weeks with succession planting. Generally, snap beans will be ready to harvest 55 days after planting, depending on the variety selected. Snap beans should be harvested before the enlarging seed can be seen through the pod, while the pods are still tender. To harvest beans, break off the stem above the cap.
Quality is best if beans are harvested in early morning hours.
Beans are best when used as soon as possible after harvest, but they can be stored in the refrigerator for a few days if cooled immediately. This applies to freezing and canning as well. For best quality, canning and freezing should be done within a few hours after picking. The plants will usually start setting more pods when the temperature becomes cooler. Insect problems may include Mexican bean beetles, thrips, aphids, corn earworms and stink bugs.
