Buying trees with the spend local card, autumn planting and annual edible flowers.

Join David Maxwell and his guests for some autumn gardening. This week David visits Ann Fitzsimons in Killinchy, where she is planting up a new border with a prairie feel using plants that don’t mind wet feet in winter. Amy Kelly will have advice on growing annual edible flowers and we head north to the Conrad McCormick’s exotic borders in Ballyvoy. Also on the programme, one listener wants to use their £100 spend local garden on fruit trees and is looking for advice on the best apple and plum varieties and how to make a no dig bed with Cherry Townsend.
