Beans Need Time

Q: I have green beans that have grown full and tall, but there are no flowers or beans! I did not have a problem with my beans last year. What causes this? 

A: A few things come to mind. First, what number is given for days to maturity on the seed pack? It could be that the beans just need more time. Your vines are nice and full, but is there any chance you overfertilized? Beans can make some amount of nitrogen on their own, so they are typically fertilized separately from corn, tomatoes or potatoes, which require more nutrients. Third, the nonflowering could be caused by our weather. Beans like summer temperatures between 70 and 80 degrees. Temperatures consistently above 85 could prevent flowering if they occur when the vines start to mature. I think you need to give your garden more time.
