In Gardeners' Corner this week with David Maxwell: a visit to Mount Stewart, where head gardener Neil Porteous is keeping the colour going with Autumn Asters. Cherry Townsend is harvesting and planting seed at Kilcoan Gardens in Islandmagee. David Love Cameron gathers in a big crop of onions at the walled garden in Helen's Bay and offers advice on how to store them as well as how to avoid the dreaded white rot. Also in the programme, Anne Fitzsimons joins David Maxwell in the studio for tips on naturalising bulbs.
