Why aren't my pole beans producing?
I planted some pole beans on 05/04, and they are growing very well, but no flowers or beans. Is something wrong? I also grew some bush beans in the container and have harvested a lot of beans.

There may be several reasons that your beans are not producing. Possibilities are lack of sunlight or overfertilization. Also, if your beans are planted too close together, the production goes way down. Cold, wet spells and excessively hot, dry periods can cause flowers to drop, reducing yields. Beans prefer temperatures between 70° and 80°F. If the maximum temperature is consistently over 85°, the flowers will drop off without setting pods.
