How to prune 'romanesco' broccoli

No pruning required; harvest the head before florets begin to open. Cut the central head cleanly with a sharp knife at the stem when spirals are compact and fully formed. Remove any outer leaves that are yellowing or soil-touching throughout the season to reduce slug damage and disease.

No pruning needed; leaf removal as needed. Romanesco broccoli is a single-harvest brassica — it produces one central head per plant and does not reshoot reliably after cutting the way sprouting types do. No pruning is needed during growth. Simply harvest the head when the fractal spirals are tight and green. Remove yellowing outer leaves if they touch the soil.
