THIS week’s instalment finds Carol Klein waxing lyrical over late-flowering clematis, while Mark Lane visits a lovingly restored walled garden in Warwick. Plus, a visit to a Yorkshire garden where foliage is the star of the show, and back at Longmeadow, Monty Don offers advice on pruning hedges and growing fruit in pots.
