yes...been looking at that
Supposedly tomatoes and beans are ok together in the ground... but there is less info about what will create a crowding issue for them in containers... I have some 7 gallon containers and will try 1 bean and 1 tomato in a few and see if there is a difference...
When remixing the soil from last year the mass of roots from the beans was surprisingly dense... I could see that possibly creating a problem for other plants in the same container. The nitrogen fixing that the bean roots do supposedly is only a benefit to the soil once the plant dies and the roots break down...
We also do use legume innoculants on the beans...
