Yes, there are a lot of veggies that can’t stand one another, LOL!
Usually it’s due to one veggie attracting a bug or a disease that’s deadly to the other one, or planting a nutrient HOG next to a veggie that needs extra nutrition.
There’s also a huge list of beneficial veggies that love one another. That’s called ‘Companion Planting’ and it really works!
