My beech hedge 12' high 10' wide v. healthy but not maintained I need to bring it back to 5' high 4'wide. When is the best time to cut back so severely, July/Aug or when dormant.A local garden centre advised to reduce the height in July/Aug and reduce the width one side this winter and the other side the following year. I would appreciate your advice before I take to cutting.
