Zone 6b · North Carolina · Gardening since age 12Green bean plants or string beans are popular among backyard gardeners because they are easy to grow, highly nutritious, and tasty beans.
Fresh beans are high in fiber and protein and low in fat, making for a yummy and healthy meal. Sometimes, I even eat them off the vine while harvesting.
Scarlet runner beans are even beautiful bean plants when they start to bloom.
They are a very cheap and practical way of addressing nutrient deficiencies in people. They grow in warm climates and have two main types of beans: pole beans and bush beans.
We are going to focus on how to grow beans the right way and address the questions of fertilizer application best practices.
What Is The Best Fertilizer For Green Beans?
Green beans do not require too much fertilizer. You can fertilize and apply some organic matter to them at least once a month during the growing season.
Green beans are different from other garden crops because they can produce nitrogen so there is no need to use a Nitrogen-high fertilizer.
It would be better to use low-nitrogen 5-10-10 fertilizer or 6-12-12 fertilizer. You can also use non-chemical organic fertilizers from compost, bone meal, or well-rotted manure.

Understanding Fertilizer Numbers
When buying fertilizer, you would often see numbers on the fertilizer packaging, such as general-purpose fertilizer with 10-10-10 on its packaging, so what do they mean?
The numbers represent the percentage of each component of Nitrogen (N), Phosphorous (P), and Potassium (K) or simply NPK. For example, 6-12-12 will mean 6% of Nitrogen, 12% of Phosphorous, and 12% Potassium.
Commercial fertilizers have different mixtures because plants have different nutrient needs.
Applying A Dressing of Fertilizer
Always make sure you follow the manufacturer's instructions in applying the fertilizer. Prepare the soil using a spade or tiller before planting and applying the fertilizer.
If you use granular fertilizer, do not place them directly on the plant but the edges a few inches away from it. You have to apply granular fertilizers a few days before planting.
Normally you would need 1 1/2 pounds (0.91 kg) of fertilizer per 100 square feet (9.29 m²) of the garden bed. Afterward, water it well so that the fertilizer is dissolved into the soil and absorbed by the root system.
However, if you are using a water-soluble or liquid fertilizer, always follow the manufacturer's instructions. Use a hose-end sprayer when using them.
It would be better to use a granular fertilizer at the start of the planting season and, after a month, change to a water-soluble or liquid fertilizer.
What Do You Feed Green Beans Plants?
As previously discussed, green bean plants need a combination of water, compost, commercial fertilizers, and plenty of sunlight to produce an excellent bean crop.
Bush beans will need around 50 to 55 days after planting before harvest, while on the other hand, pole beans will need about 55 to 65 days. Pole beans require a long time because they need more time to grow the bean vines.
Plant diseases and insects are a common threat to green bean plants. Ensure the plants enough space and avoid overcrowding since they encourage the spread of plant diseases.
How to Grow Beans
The planting season for green beans usually starts during spring, after all the spring frost has melted and the danger of frost is gone. Most garden centers won't sell transplants, but you can easily start them from seed
But you can also do it a few weeks earlier indoors when you initially plant the seeds and grow the plant seedlings. In the fall you can start as early as 9-12 weeks before the expected frost.
The green beans grow very well in organic and well-prepared garden soil.
Final Thoughts
Green beans are excellent plants because they can grow fast and provide pods rich in fiber and proteins. They are also reasonably easy to grow and require a small space in your garden.
If you follow the proper planting and caring procedures like the ones discussed in this article, you can be assured of a bountiful harvest.
They are also delicious, and mixing with other vegetables will indeed create a very delightful dish.

It can temporarily boost magnesium levels in the soil. However, beans usually grow with the average level of magnesium present in the ground and usually no need to use Epsom salt.
