lima beans grow very poorly

Question

My limas never yield but 2 or 3 pods. The soil is fertile, well drained, and everything in the garden grows beautifully. Could it be the pH of the soil? Or other ideas?

Answer 1

Too much nitrogen fertilizer will prevent pods from setting and focuses more on producing foliage growth. Heat can also be a factor, making pollination more difficult. This article might help: https://www.gardeningknowhow.com/edible/vegetables/beans/bean-blossoms-no-pods.htm
