“Gardening will never cease to amaze me,” said a gardener as they opened up a harvested pod to reveal black beans. 

From 10 black bean plants, the gardener, Roxy (@5leavesandadream), was able to harvest hundreds of black beans to use in all sorts of dishes. And beyond the culinary benefits, black beans make excellent companion plants. 

@5leavesandadream Considering I didn’t give my black beans any extra attention, I’m really happy with the harvest 🫘 If you want a low-maintenance companion plant, this one’s a winner! Not only is it easy to grow, but it also enriches the soil with nature’s free nitrogen fertilizer. 🤭 #harvest #gardentok #vegetablegarden ♬ original sound – Gardening with Roxy 🫜

The scoop

Roxy highlighted that planting black beans thoroughly enriches the soil with a free nitrogen fertilizer. Some of the best plants to grow along with black beans are corn and squash. Indigenous communities call this combination the Three Sisters garden: the corn provides support for the beans to climb while the squash shades the soil. 

Other companion plants to grow with black beans include carrots, cucumbers, lettuce, potatoes, tomatoes, and marigolds. All of these plants benefit greatly from the nitrogen-rich soil that black beans create. 

Stay away from planting onions, garlic, and fennel along with black beans — the antibacterial properties from these plants are said to inhibit the black beans’ nitrogen. 

How it’s helping

Once you have arranged which plants you would like to benefit from black beans, the benefits of a self-grown garden will be brought to your yard.
