Overview: Jim McColl, Carole Baxter, George Anderson and Chris Beardshaw are on the road to Gairloch to find out what grows and possibly also what doesn't in wonderful Wester Ross. Challenged to come to Gairloch by local resident, Helena Bowie, the Beechgrove team are ready to answer Helena's and the Gairloch community's gardening problems in a Beechgrove Gardener's question time event. To set the scene for gardening conditions in the area Jim also visits the world renowned Inverewe gardens where the Gulf Stream is used to such advantage. Despite its northerly location it boasts a range of exotic plants from around the world right there in wild Wester Ross and is the epitome of gardening on the edge. Carole also visits self-sufficient, vegetarian octogenarians, Chrissie Rennie and Bob Mapstone who garden in idyllic South Erradale.
