I am having this problem (flowers not pods), this year. I did plant in a different location and I think my issue is not enough sunlight for the beans to set pods; additionally I planted tightly as this is a new garden bed and I was using the favas to condition the soil as much as I was using them for bean production. My research and minimal experience with favas tells me that any of the following might cause the plants not to set pods: 1. Less than a half dozen hours of direct sunlight per day (also planting too tightly causes less sunlight per plant) 2. Not enough water; when the plants flower they need lots of water to set pods 3. Temperatures; too hot or too cold and no beans Despite the criteria, I have found fava beans very easy to grow; growing in soil where nothing else can manage and still getting a decent amount of pods per plant. Water is not an issue in my location, and temps are pretty much ideal for favas (almost all year round). Sunlight is the biggest issue for me as I live in a area with lots of large trees and winters here are mild but overcast. Early spring tends to be fairly overcast as well, and despite still getting 12 hours of daytime in September (fall for this area) the sunlight is not intense enough to get the beans to set pods. That is to say; if I plant at the correct time (based on daylight hours and what months I expect to have good sun intensity) the plants grow, flower and set pods rather quickly. If I plant in the offseason, the plants grow, flower and then I have a long wait until the sunlight is good enough to get my beans to set pods. It's the beginning of May(spring here), and I have favas with flowers that I planted back in or around August (late summer).... no "real" sign of pods yet (I did get a few over the course of the winter and early spring). I'm hoping to get pods in June or so. Again, I planted in part shade and I planted too tight, so much of the "not setting pods" issue was self created.
