At the London RHS show we were next to Pippa who runs the Beans and Herbs stall. We asked her what seeds can be planted now. She recommended a hardy pea, Douce Provence, and the broad bean Super Aquadulce, both of which can be bought from her website.
We also asked her about tasks in the garden for this time of year. Her advice: prepare the unplanted parts of your veg patch for next year, covering it with grass clippings, fallen leaves or compost from the bin. She also advised covering it with plastic (or old carpet if you have it) and weighting it down.
