Answer: If you haven't sone so already, cut them back to as close to the ground as possible, being careful not to damage any new growth that may have already started. An application of a complete fertilizer and/or some compost or well-rotted manure would help to revitalize them. They will also appreciate several inches of organic mulch and an occasional deep watering if the summer is another dry one. They should grow bigger and better for you every year.
