Carrots Love Tomatoes says dill grows well with cabbage. It grows well in the holes left by beets. Light sowings may be made with lettuce, onions or cucumbers.
Dill does not do well by carrots & will reduce the growth of carrots if allowed to go to seed.
The black swallowtail butterfly lays its eggs on dill, fennel, and parsley. Its beautiful black and gold caterpillars are ravenous eaters. Personally I don't like butterflies well enough to put up with the damage from the caterpillars.
I hope this helps. If I find more information I'll post it.
GOD bless and keep each of you.
