How Late Can You Plant Green Beans

You need to allow yourself at least 2 months (look for a variety that matures in about 45 days for best results) of growing time before your first frost hits, which will take them out. So if frost doesn't hit till October or so, get those beans in by mid-July/early August at the latest.
