Box hedges make elegant boundaries to home gardens and lawns. But without a regular pruning schedule, hedges can look messy and overgrown. Evergreen hedges grow quickly and can be trimmed up to three times a year. Thorough shaping should be done in mid-August in time for new growth to emerge before the growing season is over. An electric hedge trimmer makes easy work of cutting box hedges and reduces uneven cuts.
Put on safety goggles and thick gloves for protection against scrapes and cuts.
Plug in electric trimmer to a safety socket or circuit breaker. This reduces the risk of injury and ensures that the engine will cut off if there is an accident.
Drape electric cable over one shoulder and keep away from blade throughout trimming process.
Make slow, controlled motions with your electric trimmer to cut off stray branches until top is completely flat.
Work your way along the upper edge of your hedge and trim the top 1 to 2 inches. Step back 2 to 3 feet occasionally and be sure your work is even.
Return to your starting point and trim the next 1 to 2 inches of hedge. Always use slow, controlled movements to make even cuts.
Trim the sides into a flat plane. Keep the top slightly narrower than the base to provide support for the weight of the hedge.
Remove cut branches from the area around your box hedges. This keeps the area looking tidy and prevents the spread of fungal diseases.
