There is lots of late summer harvesting to do at Beechgrove. Jim McColl is back in the main vegetable plot harvesting fennel, celery and parsnips, while Carole Baxter tackles something different - tomatoes with tomato fruits above ground and potatoes below ground, as well as artichokes and oca, one of the lost crops of the Incas. Carole and Jim also take a look at some autumn colour around the garden and Jim visits Megginch Castle near Perth, where there has been extensive replanting of its orchard and they now have a near-complete collection of heritage Scottish fruit varieties.
