Can I Plant Onions and Beans Close Together?
Asked by GardenGnome42
I'm curious about planting onions and beans near each other. I know the general advice is to keep them apart because onions release a gas that can inhibit bean growth. I'm not looking to inter-plant them, but I want to have about 1.5 feet (around 0.5 meters) of space between their beds. Is that enough separation?

Haha, yeah, I've heard that beans can get a bit grumpy due to the gassy onions! But here's the scoop: onions release a compound called allicin that keeps bad stuff away, and that can interfere with the nitrogen-fixing bacteria beans rely on. So if you're planting them in adjacent beds, it's good to keep that in mind. The spacing you mentioned should be fine though!

I actually have a row of beans super close to my onions right now, and they're thriving! The onions are bulbing up nicely while the beans are flowering and producing. I plant onions in the fall and beans in spring, so the timing doesn't overlap much, which seems to work for me!
FarmingFanatic: Sounds like your method works great! Timing can make a huge difference.

As long as you're using raised beds with separate soil, you should be fine. If it's just a couple of rows in the same soil, the onions might hurt those essential soil bacteria the beans need. Your spacing looks good, but just double-check if you think their roots will mix!
TomatoTamer: Right? If they’re in separate beds, I think you’ll be just fine!

SoilSavant99: True! The 1.5 feet separation can help prevent any issues since they won’t be competing in the same soil.
