What is the reason why beans do not grow vines?

Green beans are a common vine crop, but during their cultivation, many people often encounter the situation where the beans do not grow vines, which not only affects the differentiation of flower buds, but also affects the growth of beans. So what is the reason why beans don’t grow vines? Let’s learn more about it below.

1. Variety factors

Different varieties of beans grow differently, and some varieties may not be easy to grow vines.

2. Insufficient light

If beans are in an environment with insufficient sunlight for a long time, they may choose not to grow vines. This growth method allows the beans to get sufficient sunlight more easily.

3. Temperature discomfort

The suitable temperature range for the growth of beans is generally around 20-30℃. If the temperature is too high or too low, it may affect the normal growth of beans, including the growth of vines.

4. Planting density is too high

If beans are planted too densely, competition between them will be fierce, limiting the growth of the plants and making it difficult for them to cling to land. At this point, the bean plants may enter a competitive low growth state and not produce vines.

5. Moisture problem

The soil is too dry and the bean roots cannot absorb enough water to support the growth of the vines. Or there may be too much rain, poor drainage, and waterlogging in the fields, which can suffocate the roots of the beans, affect the growth of the vines, and in severe cases cause the plants to die.

6. Improper fertilization

Long-term application of large amounts of fertilizer, especially excessive nitrogen fertilizer, will lead to excessive vegetative growth of the bean plants, excessive growth of branches and leaves, and consumption of a large amount of nutrients, thereby inhibiting flower bud differentiation and vine growth. In addition, lack of phosphorus fertilizer will also affect the flowering and fruiting of beans and the growth of vines.

7. Improper pruning

When the bean seedlings grow too vigorously, if they are not pruned in time through topping, pruning, and crossing, to remove the apical dominance of the plant and control the growth height, nutrients will be concentrated on the branches and leaves, which is not conducive to the growth of the vines.

8. Impact of pests and diseases

During the growth process, beans may be attacked by various pests and diseases, such as thrips, red and white spiders, weevils, green stink bugs, rust, anthracnose, etc. These pests and diseases can harm bean plants, causing flowers and fruits to fall, thus affecting the growth of vines.

In general, the reasons why beans do not grow vines may involve multiple aspects of the above problems. In the actual planting process, corresponding measures can be taken, such as reasonable fertilization, adjusting planting density, controlling temperature and light conditions, etc., to promote the healthy growth of bean vines.
