Proper landscaping starts with a plan, which may involve a homeowner calling in professional help. That's according to Jeff Peters of East Hampton, who started his landscaping company, JCP Landscaping, in 1999. He works throughout East Hampton, Bridgehampton, Sag Harbor, North Haven, and Water Mill. Many of his 16 employees have been with him for 20 years. Mr. Peters shared some landscaping advice with The Star.
