Some plants make good neighbors in the vegetable garden and some don’t. Find out what are the best green bean companion plants.
Companion planting is a practice of planting plants together in the vegetable garden that support each other’s growth. There are plants such as sunflowers that have great properties, such as feeding birds and removing heavy metals from the soil, that have bad properties too.

Sunflowers stunt or impede the growth of other plants with chemicals they give off as they grow. It’s best to grow them on their own.
Green Bean Companion Plants
Green beans are a wonderful plant for eating as well as putting nitrogen into the soil. There are small nodes on the end of the plant’s roots that contain nitrogen. They leach it into the soil as they decompose and feed the other plants around them. Click here for how to grow green beans in your garden.
Many other plants are heavy feeders meaning they need a ton of nitrogen to grow and produce well. Planting them next to green beans could help them attain more nutrients from the soil and thrive.
Bush bean companion plants
Green beans come in two types, bush beans and pole beans. Bush beans grow on a little bush and pole beans grow in a vining pattern and need to be trellised. The same companions work well for both pole and bush bean varieties. The exception would be if you wanted to grow something tall for the pole beans to trellis on.
The cherokee people have a method of growing called the three sisters where each plant helps the other plants grow in a symbiotic relationship. The traditional three sisters method uses corn as the trellis for the pole beans and the pole beans feed nitrogen to the corn.
In addition, they plant summer squash with the combination, and this shades the roots of the other two plants. The three plants work in harmony to feed, shelter, support, and repel pests from the other two in the group.
Flea beetles are a common pest that attack green beans and catnip repels them so catnip is a great companion plant for green beans.
Beans can tolerate light shade that is given by corn, so this makes them great companions as well.
What to grow with beans
