I can not find anything on plating radishes with tomatoes, is there a reason for it or should they be fine with them? As for Dill, I read that some say it is okay while it is still young but not while it is mature and other sources say nothing. Does anyone know why you shouldn't plant dill with tomatoes? Is it okay to plant in another part of the garden as long as they don't share the same soil? Can you put a pot of dill next to a tomato without the same deleterious effects to the tomatoes? I have a lot of charts for the rest thanks to many of you on here. Just trying to get everything set up for some raised bed gardening. moderator's note: added a more descriptive title to topic
Dill does improve the growth and health of tomatoes when it is a very young plant, but as Dill gets older it attracts the tomato hornworm and it retards tomato growth. I would just plant it far away from the tomatoes and not worry about it. I can find nothing about radishes being helpful or harmful for tomatoes, so it would appear that they are neutral companions. You can either plant them together or not it doesn't matter.
They say that basil planted with tomatoes keeps some bugs away !! !! I planted it with my tomatoes last year simply because it was the only place I had vacant !! If you are making spagetti it is a bit easier just to go down one row and get what you need !!! It would seem that radishes planted with tomatoes would take up moisture needed for the tomatoes to be at their best !! I think I would not try it !!
There was a time I'd make myself crazy trying to assure companion planting. The reality here is that some has a basis in science and some is old wives tales. I don't really know which is which. So, what I do now is figure out what I want to grow and check the companion chart to make sure I'm not doing a well established NO NO--like planting fennel near my other veggies. This year I have a few bush beans growing in one strawberry bed. I wanted early green beans and I'm out of space. I have very happy strawberry plants in the bed with the beans. I can't prove that the beans are what's causing these happier plants, but the bush beans are supposed to add nitrogen into the soil. And when I cut or pull up the bean plants, I'll be using them for mulch.
I try to companion plant as best I know how. No onions near beans or peas. No tomatoes near potatoes. Dill is not supposed to be good near tomatoes, but I have grown them together and just keep an eye out for Horn worms. Marigolds are great for tomatoes, I think. I plant Parsley and Basil with tomatoes.
