How to Cut a Hedge Straight
HOW-TO
The short answer
Use a string line and canes as a guide, cut the sides first, then the top, and check from a distance.
A straight hedge needs a guide, not just a steady hand.
Set up a guide
Hammer a cane at each end of the hedge and stretch a string line between them at your target height. Use a spirit level to confirm the line is level, adjusting for slopes.
Cutting to the line
Work along the string with the blade flat. Take off a little at a time and stop when the top reaches the string.
Sides
Use a plumb line or your eye to keep the sides vertical or slightly tapered.
