Hedges are ornamental plants, usually trees or shrubs, used in the yard to protect the homeowner's privacy and beautify the landscape. Hedges are also used to mark boundaries on a property. Shrubs and trees used as hedges need to be trimmed regularly to improve appearance and ensure the hedge stays on your side of the property. Tall hedges are dense and compact, so as soon as thin, spindly branches appear, the whole aesthetic is ruined.
Cut the top of your hedge at the desired height. You may need a ladder to read the top. Doing this several years in a row will ensure it grows to the height you prefer.
Trim the sides so that they are equal on each side, being wider at the bottom of the hedge and thinner at the top, like a pyramid. Cut away any long branches that stick out from the hedge. Use heavy cord attached to the ground and tied to the top of the hedge to determine the best angle at which to cut the hedge and keep lines straight.
Remove any branches that are dead or broken to prevent disease.
