Not every vegetable is worth the space on a UK allotment. In this episode, we make a practical, UK-specific “do not grow” shortlist — crops that often struggle with our cool summers, need too much protection, or take up loads of space for a small return. From sweetcorn and aubergines outdoors to fussy celery, pest-prone brassicas without netting, and carrots in heavy soil, this is a reality check designed to save you time, frustration, and wasted bed space. The goal isn’t to grow less — it’s to grow smarter.
