Answer: Beans are considered "heat-loving" vegetables, but they do have limits. Ideally, temperatures should fall no lower than 55F, and blossoms may drop if night temps remain above 70F, and days run in the 90s. You will need to cool your greenhouse with a fan and use a shade cloth over the windows to keep the greenhouse from getting too hot. Plant new bean seed every few months, because after a while a vine will "run out", meaning that it will be less vigorous and healthy as it ages. Successiveplantings will ensure that you always have a healthy, productive vine to keep you company!
