Here are 7 steps you can follow to fix yellow leaves on beans: Improve Draining Systems Bean plants have shallow roots hence the moisture content of the soil has to be perfect otherwise, you will risk the bean plant developing yellow leaves. Improve Alkalinity Since soil pH level plays a crucial role in maintaining a healthy bean plant, you must take the necessary measures to make the soil's acidity level convenient with bean plants.

It's also bad when you overwater them because it smothers the plant, and again the plant battles to get the nutrients it needs to grow. Always check the soil moisture before applying water. Put your finger into the soil for an inch or two and test the amount of moisture already there. If the soil is moist, allow the soil to dry out a little and don't water for a few days. Your beans need about two inches of water per week. Keep your watering balanced, and it will help stop the yellow leaves from appearing. Good Fertilizer Bean plants are light feeders, which means they do not need excessive fertilizing to grow. Before planting the bean plant, put a fertilizer in the soil. You can get a test kit that will tell you what’s wrong with your soil so that you can add whatever it needs to be in good condition. Green beans produce nitrogen, so do not buy a nitrogen-rich fertilizer. Compost is of great help and can make a difference to the health of your plants. This will increase your chances of having a prosperous bean plant with little risk to yellow leaves. Why Are Leaves Turning Yellow?

The irregularities in the soil make it hard for bean plants to grow and look lively. What are the specific problems in the soil that led to bean plants having yellow leaves? 1. Draining 2. Alkalinity 3. Diseases and viruses The first reason can be the draining system of the soil. If excessive water stays in the soil for a long time because of a poor draining system, the roots of bean plants will rot and yellowish leaves. The second reason is the alkalinity of the soil. The soil must be at the right pH level to prevent developing yellow leaves in your bean plants. If your soil has a proper draining system and still produces yellow leaves, you better watch out for the alkalinity of the earth. The third reason for the yellowing of leaves is diseases and viruses. When the bacteria is to blame for the yellowing of leaves, you will notice water spotting or dry leaf edges. A common infection caused by bacteria is called halo bright, which causes yellow spots on a bean plant. When the suspect is a viral infection, you will notice multi-colored spots on the leaves responsible for developing yellow to brown leaves. The typical virus infecting the bean plant is called the mosaic virus. Final Thoughts The causes of yellow leaves on bean plants are not difficult to counteract. Most of them are common problems that some of us may forget to investigate. Remember to always protect yourselves by wearing gardening gloves whenever dealing with diseases. Every step provided in this article, and you will be guaranteed healthy bean plants – free of yellow leaves. Jenny Marie Tribal Writer Edited By Patricia Godwin
