About Broccoli
Broccoli is a heavy-feeding crucifer that attracts cabbage white butterfly. Aromatic herbs, trap crops, and careful spacing reduce pest pressure without overcrowding.
Autumn–spring plantings suit most NZ regions; summer crops need shade and steady moisture.

Avoid planting together

Broccoli and tomatoes compete for nutrients and space — rotate beds rather than interplanting in the same season.
Bean (Bush) Nitrogen fixationBeans supply nitrogen for heavy-feeding broccoli — interplant at row ends or in prior-season green manure.
