Why broccoli and turnips work together
Garden charts recommend it. 2 garden chart entries recommend growing them together. Charts pass on gardening tradition; they are not tests.
Trap cropping to control Delia radicum populations in cruciferous crops: first results and future applications (Rousse · 2003 · Entomologia Experimentalis et Applicata)No clear effect on pests. In a field trial, growing them together made no clear difference to pests.
Relative Susceptibility of Brassicas to Cabbage Maggot (Diptera: Anthomyiidae) Infestation. (Joseph SV. · 2023 · Insects)Same family, shared pests. Broccoli and turnips are both in the Brassicaceae family, so the same pests and diseases can move from one to the other.
