It might be too hot for them. They are a cold weather plant. You can let them grow over the summer and they will set a few pods again in the fall, then tear them out and plant new ones right away to grow over the winter.

happyday I planted some Fava Beans last week that are just starting to come up. I knew it was the wrong time of year but just wanted to see what they would do. I was hoping I could keep them alive through the summer and was expecting them to over winter them and produce a crop. Is this unrealistic? If they live will they produce a crop or do they really need to pulled and plant new seed later in the year?

In the past I planted them around June 1st, and they grew and set a few pods then blooms failed as it heated up. I let them grow all summer, and the stalks got taller and twisty. In cooler fall, blooms set pods, but they were smaller, having only one or two beans rather than three to five beans of the earlier pods. Then the frost killed the plants.

In your zone, you may get a different growth pattern. They might live for a year or longer, and produce well all fall and winter, or you might find that the summer sun will kill them. If they live through the summer you might get bigger pods in your fall then I did in my spring.

I'd say let them live and see what happens, and let us know how it goes. They don't need to be pulled unless you have to have the space for something else, so have some fun with the experiment. If they live you will get some extra beans and can still plant more new plants in the fall. If they die, you know not to plant in the late spring again.

Thanks happyday, I will give it a try. I planted some last October that made it through the winter fine even with a massive aphid infestation. I did not have them in a good spot though. This spring I had to pull them to make room for my pepper garden. The ones I just planted are where they will get full sun all winter. I will do my best to keep them alive this summer and report back.
