Just looked up Earth Box Gardens. Nice concept, but you (THEY say) only plant two tomato plants per box. Heck, we would need two or three just for the maters! Then there would be the green beans and the corn and...

OK, we MAYBE could get by with two boxes for tomatoes but I don't know if one box (8 plants) would be enough for the beans (conventional green beans I am guessing according to their planting guide) and one would probably work for pole beans and MAYBE corn. This would maybe allow for having enough produce to actually put up some corn, but I am not sure about the beans and it for sure wouldn't allow for enough tomatoes to make in to juice.

Have you found out if you can plant (successfully) more than two tomato plants per box?
