Temperature is a key factor affecting bean production. High (above 85 degrees F)
and low (below 70 degrees F) can cause plants to create flowers but not beans.
Inconsistent soil moisture can also inhibit bean development and is exacerbated by
hot, dry winds.
Proper crop management is the best way to mitigate these problems. Mulch
surrounding plants regulates soil temperature and moisture. Using a windbreak crop, such as corn, can protect the bean plants from drying winds. Harvest regularly to encourage plants to continue producing. If beans are left on the plant past their peak harvest time the plant will use energy to produce seed rather than create new beans.
