Snip overgrown branches and limbs inside each bush. Clear enough space for sunlight and air to pass through and stimulate healthy growth. Make sure to prune the base near the roots as well. Position a taut rope or string across the top and bottom of your hedge to establish a guideline.
Hedge trimmers, whether gas, electric or battery powered, are ideal for cutting hedges and thin branches up to about 3/4 inch. Anything bigger than this could snag on the teeth of the trimmer and cause it to seize up, so it's best to use a more powerful hedge cutter or chainsaw for larger branches.
Don't prune hedges during very hot, dry weather, and prune well before your first frost date. Try to prune on a cloudy day to avoid excessive leaf burn.
Even the heavy-duty hedge trimmers with wider grooves don't have the horsepower to cut through tree branches. Fact is, hedge trimmers can't do the job of more suitable trimming tools like pruning shears or loppers. For the best results, use one of these three essential tools for trimming trees.
