Green beans are typically ready to harvest about 50 to 65 days after planting, depending on the type. Bush beans are usually ready in about 50 to 55 days, while pole beans take around 55 to 65 days to mature. The best time to pick green beans is when the pods are firm, about as thick as a pencil, and snap easily when bent. It is ideal to harvest before the seeds inside the pods start to bulge and the pods become tough or stringy. Fresh beans should be tender with seeds barely visible as bulges inside the pod. Picking regularly encourages more beans to grow, especially for pole beans which can continue producing for a month or two if harvested consistently. The pods should be snapped or cut off carefully to avoid damaging the plant.
