Eric Robson and the panel are in Cardiff. Matthew Wilson, Bunny Guinness and Matt Biggs answer the audience's questions.
This week, the panellists recommend garden uses for sheep fleece, offer advice on overwintering chillis, and give the definitive 'dos and don'ts' for starting an allotment.
They also offer up a whole host of interesting and varied planting suggestions for one questioner with a riverbank garden, one looking to attract pollinators with fruit and veg, and one who is looking for plants to remind his wife of Yorkshire.
Finally, Matt Biggs lets his inner-thespian run amok as he investigates Shakespeare's connections to plants and horticulture.
