- 1). Identify the property line between your yard and your neighbor's. This may have been marked for you during a survey before you bought the property. There may flags placed in the ground or some other clue to show where the line is. Do not assume that a fence is the exact boundary line.
- 2). Locate the part of the hedge that hangs onto your property and which you can trim without trespassing onto your neighbor's property. In general--and this may vary from state to state--you can cut any limb or branch that hangs onto your property at the point it crosses the line, but not do anything to destroy the growth of the rest of the hedge or kill it.
- 3). Give your neighbor a heads-up that you'll be trimming your side of the hedges, if possible. This may not be required by law, however it may prevent some animosity. Some notice may also spur the neighbor to offer to trim your side herself so that the hedge will be symmetrical on both sides.
- 4). Use hedge clippers or an electric trimmer to trim on your side of the property line. If necessary, use a ladder to reach branches that are high up. Avoid walking into your neighbor's yard to reach certain angles, as that may be construed as trespassing.
