August is the height of summer and the time when many of us are outside non-stop enjoying our gardens and making the most of the sunshine. But if your flowers and plants are looking past their best and starting to flag, knowing which perennials to cut back in August for a flush of autumn flowers will ensure that your garden is soon looking tip-top again.
‘Cutting back some long-flowering perennials in August is a great way to keep your borders looking fresh and, in many cases, encourage a second round of blooms as we head into early autumn,’ says David Denyer, flower and garden expert at Eflorist.
