Bad Companions or enemies usually means that they would compete for the same nutrients causing smaller
plants and less produce. It can also mean a change in flavor.
Here is what my list has as far as good and bad companions for the veggies you want to
plant.
Tomato friends: carrots, celery, cucumber, marigold, nasturtium, onion, parsley,
pepper.
Tomato enemies: Cabbage, kohlrabi,
potato.
Lettuce friends: Beets, cabbage, carrot, cucumber, kohlrabi, onion family, radish, strawberry.
Radish friends: Carrot, cucumber, leaf lettuce, mustard, nasturtium, parsnips, pea, pole bean.
Spinach friends: Cabbage, strawberry.
pepper friends: Carrots, eggplant, okra, onion, parsnip, tomato.
Hope this helps
