As part of BBC2′s Harvest, Gardeners’ World celebrates the bounty our gardens have to offer at this time of year. Carol Klein is out and about gathering a wild blackberry harvest from the hedgerows and discovering a surprising number of more domesticated brambles that we can grow in our gardens. We join a champion vegetable grower in Yorkshire as he prepares for the biggest show of the season and Monty Don is at Longmeadow enjoying the fruits of his labours.
