In England, “high hedge” laws regulate Leyland cypress height disputes. In the U.S., you can cut the top off a healthy hedge without killing it, but expect vigorous regrowth requiring trimming twice each summer.
Never cut back into the brown, leafless interior—those branches won’t resprout. Only trim green growth.
