The short answer

Check for nests, cut the sides first from the bottom up, keep the base wider than the top, then do the top last. Take off a little at a time and finish with a tidy-up.

A good hedge trim is mostly preparation and technique. Here is the method, step by step.

Before you start

  • Check for nests (see our nesting season guide).
  • Wear eye protection, gloves and sturdy footwear.
  • Check the blades are sharp and oiled.
  • Lay a tarp or sheet to catch clippings.

Step by step

  1. Set string lines or canes if you want a straight top.
  2. Cut the sides first, sweeping the trimmer upward from the base.
  3. Keep the blade flat to the hedge surface.
  4. Taper the sides slightly so the base is wider than the top.
  5. Trim the top last, working from one end to the other.
  6. Stand back and check the line; adjust any high spots.

Finishing

Rake or sweep up all clippings, then clean and oil the blades. Water the hedge if it is dry.
