Bean Issues

Sometimes a plant that has a different coloration than the original plant can be a weaker plant (purple, white, etc.). They might have a tougher time fending off diseases that might attack. The spots on the purple part of the leaf look like they may be the beginning of a bacterial or fungal leaf spot disease. You really can’t tell for sure without lab testing. That being said, there are precautions to take to fight against this: 1 – remove and dispose of all affected plant parts; 2 – provide the plant it’s optimum growing environment regarding light, water, soil type; and 3 – avoid overhead watering as this can spread the disease with the splashing water.
Beans and peas are members of the Legume family of plants. The following quote from the website www.groworganic.com explains this principle perfectly: “Legumes work in harmony with a group of bacteria that live on their roots. These bacteria take nitrogen from the air and äóìfixäó or concentrate it in pink root nodules, adding nitrogen to the soil in a form the plants can absorb. We advise using inoculants with legume cover crop seeds to give an extra boost of rhizobacteria. Average soil has some rhizobacteria, but not enough to fix a large amount of nitrogen.” This could be your missing piece of the puzzle as to why your peas and beans are a little yellow.
