If the leaves of your beans are turning yellow and you are thinking if it can be fixed, well, we’ve got this under control. First, let’s find out the possible reasons why the leaves turned yellow.
Beans grow better in hot weather and should be planted around two weeks of the last frost date depending on the condition of the soil. It is a known fact that beans are a highly nutritious crop and have a high content of carbohydrates and protein.
Some factors such as pests and diseases can cause the leaves of your beans to yellow. Therefore, planting beans requires a great deal of attentiveness and care to produce good beans.
WHY THE LEAVES OF BEANS TURN YELLOW?
Excessive watering is one of the causes of yellow leaves in beans. When the soil is soaked or not well-drained. The plants are absorbed in water, and this can cause root rot, which will then lead to yellow leaves.
Nitrogen deficiency can also cause the leaves of your beans to turn yellow. To fix this you can fertilize after harvesting and planting in the fall, rotate nitrogen-fixing crops, or use high-nitrogen commercial fertilizers.
Diseases such as fungi in the soil can destroy your hard work. It can cause the leaves of your beans to become yellow as the roots may begin to die. These fungi strive well in soggy soil. To avoid them, plant your beans in well-drained soil.
The bean rust is also caused by fungus. In this case, the leaves turn yellow and drop. Pests such as Aphid can also cause your leaves to turn yellow and wrinkled in the affected area. The result of Aphids feeding on your beans plant is that it becomes stunted therefore causing a loss.
HOW TO FIX YELLOW LEAVES ON BEANS
Yellow leaves can be a sign of distress and lack of Nitrogen deficiency even though their primary source of nitrogen is from the air.
The yellow leaves on the beans, once the leaf turns yellow completely, it becomes clear that it is no longer supplying energy for the plant and it should therefore be discarded. If allowed to develop naturally, the leaves will eventually wither and fall off.
If you want to speed things up for aesthetic reasons, gently pull the leaf to see if it is ready to fall off. So, to fix the yellowing leaves, you may need to add some nitrogen fertilizer to it.
Ensure to put the fertiliser well,around the drip line. Water the plant, make sure the water gets into the soil around the plant.
There may be on effect on the already yellowed bean leaves but after some days you will notice that the new growth on your beans is greener.
It is quite impossible for yellow leaves to turn green again. If the leaf is resistant, please don’t tear it off! Instead, use scissors close to the stem to trim the leaves.
IN CONCLUSION
There is no cure for plants that may have been affected by diseases, so if land or beans have a history of infection, you want to avoid planting in the soil for a while to avoid reoccurrence.
Also, to avoid the possible cause of the yellow leaves from spreading to the other plants, there are certain things we must do. First, ensure that the roots are getting enough nutrients from the soil.
If plants are not deeply rooted there is every tendency that a heavy rain must have washed away the soil at the surface of roots. This is why it is important to cover the soil where your beans are planted to avoid malnutrition, which can cause the leaves to turn yellow.
