So I wonder what a good mix would be? They also are anti fungal which helps. Oregano is one plant recommended in most companion planting books. I do know that the tomatoes next to it did real well as far as growth but not as good in production. The one that had stinging nettles next to it the root system was huge compared to others and many tomatoes. I think I’ll do an experiment this year. Putting the tomato that did so well last year next to oregano and the nettle individually. Then take the one that didn’t do well last year and do the same. Which means I’ll have to start more of the green tomato seed from last year. Interesting.I understood that. But the aromatcs are known of repealing outher PLANTS too. So it isn't a good Idea to plant the to close.
