The most common reason for bean blossom failure is lack of water. The second most common cause is too much sun or shade. If the plants are not watered enough, they will never bloom at all!
There are many reasons why beans don’t make pods when grown under ideal conditions. Most likely there are several causes and each one may have its own solution.
In order to solve the problem, it’s necessary to look into different factors which may affect the issue. Let’s start with the first factor:
1. Lack of Water
When you plant beans, you need to provide them with plenty of water during their growth period. However, if your soil doesn’t hold enough moisture, then your plants won’t get enough water and they’ll die from lack of water.
If you’re using a soil that holds very little water, then you might want to consider planting your beans in a location where there is more rainfall. Rainfall helps increase the amount of moisture in the soil so that it can support your plants’ needs.
Another option would be to dig a well and fill it up with water. You could even use rainwater collected from the roof of your house for watering your garden. If you lack the funds for this project, then you could always ask a friend or neighbor to chip in.
Note: If you decide to use pond water or river water, then make sure it’s been properly filtered and cleaned first. Otherwise, harmful chemicals or bacteria could build up in the soil and ruin your bean crop!
2. Lack of Sunlight
Beans grow best when they have a lot of direct sunlight. If your plants don’t receive enough sunlight, then they may not grow strong enough to produce flowers and beans.
It’s best to choose a location for your bean crops that has access to sunlight from early in the morning until late in the afternoon. Also, try to avoid planting your bean crop under trees because these leaves will absorb most of the sunlight that would otherwise reach your plants.
3. Soil Conditions
If your bean crop’s soil is not fertile enough, then your plants won’t grow fast enough to produce flowers and beans. Beans need a nutrient-rich soil that contains plenty of organic matter in order to grow strong and healthy.
You can add organic material like fallen leaves, compost, or manure to your soil in order to make it more fertile. Make sure to till the organic material into the top few inches of soil because beans grow deeper under the ground.
On the other hand, your soil may be too fertile. This can also cause bean plants to fail to produce blooms and beans. If this is the case, then you may need to fertilize your crops less in the future.
