The Q&A Archives: Yellow Color on Bush Beans

Question: I have planted some 'Kentucky Wonder' pole beans and some 'Dandy' bush beans. All of my bean plants do not have a good healthy green color but they look rather weak and have a yellow-green color. Last year my beans grew great but this year they look terrible. Any ideas?

Answer: Usually yellow leaves are a sign of nutrient deficiency. Though your soil may have plenty of "food" for your beans, thanks to the recent cool spell, the soil may be too cool to make less mobile nutrients, such as phosphorus, available to plants. They usually recover as the season progresses, but if you want to give them a boost, foliar feed them with a fish emulsion/seaweed fertilizer. Hope this helps!
