I have four established cherry tomato plants in one of my raised beds. The only other thing in the box with them right now is a few basil plants. I would like to do some fall seed planting (mostly root veggies) in the same box along with the tomatoes but I just noticed the tomato root systems have completely taken over the entire box even though the tomatoes are only on one side. Is it OK to plant other vegetables among all the tomato roots?
