Late summer colour, Irish roses and Hunting Brook

David Maxwell travels to the hills of County Wicklow where he explores Jimi Blake’s Hunting Brook garden in late summer. Jimi pushes the boundaries of what it’s possible to grow in Ireland a thousand feet above sea level and tells us how we can stave off autumn for a another month. David Kenny is one of the few Irish rose breeders left, so what makes the perfect Irish rose? All that and the team will be taking your calls on the usual numbers or you can email anytime on gardenerscorner@bbc.co.uk
