Why do kidney beans not bloom and their leaves turn yellow? How to solve the problem of kidney beans not blooming and their leaves turning yellow?

Kidney beans are very common in our daily life. People often like to grow some at home because of their high nutritional value and good health care functions. However, many people have encountered the problem of yellowing leaves when growing them. So what is the problem with kidney beans not blooming and yellowing leaves? How to solve the problem of kidney beans not blooming and yellowing leaves? Let's take a look.

Why are kidney beans not blooming and their leaves turning yellow?

1. The soil is poor and lacks nitrogen, phosphorus and potassium fertilizers. The soil around the roots is too compacted during planting, causing slow root growth. This affects the late development of the flower buds of the entire plant.

2. Planting too densely makes it difficult for sunlight to penetrate, reducing the opportunity for photosynthesis. Kidney beans are short-day plants and need plenty of sunlight.

3 Rain or too frequent watering will cause root rot, while kidney beans are drought-tolerant in their growth habits. In addition, too much water for a long time will cause red root disease in the roots. A humid environment will easily breed nematodes and bacterial diseases, which will cause the leaves to turn yellow.

How to solve the problem of kidney beans not blooming and leaves turning yellow

It is recommended to check the problem carefully and apply water appropriately. For nematode damage, use Jianzhibao anti-nematode fertilizer. For bacterial diseases, use 200 ml of Jiu Miao No. 1 plus 1.6 million units of agricultural streptomycin and spray once every 8 days. If there is a lack of nutrients, use ferrous sulfate or potassium dihydrogen phosphate.

What is the problem with kidney beans having lush leaves but not producing fruit?

Autumn kidney beans have higher requirements for the growing environment than cowpeas (long beans). When the temperature exceeds 30 degrees, the assimilation of kidney beans and the division of pollen mother cells will be hindered, affecting the pollination rate of the flowers. Cowpeas have strong growth potential, are drought-resistant and slightly tolerant to high temperatures. Therefore, we have the habit of planting cowpeas in greenhouses, while some varieties such as kidney beans and elephant-frame beans have mostly failed but few have been successful. The main reason is that kidney beans are not suitable for the higher temperature growing environment, and usually there are no beans to pick after the seedlings are harvested.
