Usually, Kentucky pole beans take about 50 to 65 days to harvest, so something may be wrong, although you might wait a week or two to be sure. Could it be that the plant has received too much nitrogen? This encourages leaves over flower formation. High heat, or starting seeds too early, can affect flowering as well. Make sure that the plants have at least 6 hours of full sun each day, and enough water.
