I have about 24 strawberry plants, not all the same variety. In the autumn I tidied them up by cutting off all bedraggled leaves, doing exactly what Monty Don told me to do in the September or October Gardeners' World. Due to the very mild weather they went on growing as though it was Spring even produced flowers. Now they are a horrible sight, loads of yellow leaves all looking very unhappy. It is only their second year so I am not about to replant. Any advice as what I should be doing and when to do it?
