Know the Basics Before Cutting Hedges
If this is your first-time cutting the hedge, you’ll want to know the basics to keep yourself safe before you start.
- Following basic safety practices including eye, ear, hand and feet protection.
- Wear heavy-duty clothing to better protect yourself, including pants.
- Make sure that the power cord and extension cord are firmly in place.
- The trimmer blades should always be well-lubricated before and after cutting.
- Check the site of the hedges and be sure to remove any obstructions or objects that may be a safety hazard.
When holding the trimmer, be sure to use the front and backhand grip and to grip these areas tightly. You’ll also want to place your thumb under the handle. Always keep your hands behind the protective guard and away from the blade for added safety.
Keeping the blades sharp is important because dull blades can cause the blade to snag and can make cuts uneven. Resin solvent can also be used on the blades and will confidently remove sap and other buildup on the blades that can impact the trimming process.
You can sharpen your blades at home or bring them to a shop if you’re not comfortable sharpening them.
Step 1. Plan Your Hedge Design
Before you start cutting, keep in mind the overall design you want to achieve. Hedges can make excellent privacy screens, add structure to the garden or add a bit of personality to your landscape.
Take a look at some of the ways you can use hedges in your overall landscape design.
Add interest to the front of your house with carefully planted and sculpted hedges.
Plant a living privacy screen in the backyard with a tall hedge.
If you like a whimsical feel, you can trim hedges in the shape of animals or people.
Add structure to the landscape with a low hedge along the border of your property line.
Create an interesting landscape is by using hedges to highlight a focal point in the garden.
Step 2. Connect the Hedge Trimmer
Of course, the first step is to connect your trimmer and make sure that you have an ample extension cord length for larger trim jobs. Make sure that the extension cord is safety-rated, and account for the height of the hedge when deciding on extension cord length.
Keep the cord behind you for added safety when trimming.
Step 3. Work Your Way Up
Always start from the bottom up when trimming hedges or shrubs. The goal is to start at the bottom and slowly work your way up. Don’t apply too much pressure to the trimmer and make sure to take your time.
Trim the hedge slowly and pay close attention to the depth of your trim.
If you cut too far into the hedges, you risk making the hedge look uneven which is not what a professional cut will look like.
Make sure to follow these tips:
- Don’t force the trimmer- allow it to do the work for you
- Use a sweeping action to shape thinner branches
Step 4. Angle the Sides
The sides of the hedge require a little finesse to get the shape desired. Hedges narrow at the top and widen at the bottom, so you’ll need to cut the sides of the hedge on an angle. An angle is important for aesthetics, but it’s even more important for allowing sunlight into the hedge.
When the sides are properly angled, you’ll allow sunshine to reach the hedge’s root system to allow for steady growth.
Step 5. Cut the Tops
Cutting the top of your hedges will result in a more professional look. A lot of homeowners are scared to cut the tops, but it’s rather easy once you know how professionals trim tops.
You’ll want to guide the trimmer left and right while holding the trimmer level at the top of the hedges.
Go slow and make sure to only trim a few inches at a time. Concentration and patience are key for an even cut. Tops are cut last because you always want to start from the bottom up with your hedges.
If you are worried the final cut will be uneven, you can use a set of stakes connected with a string next to use as a guideline when trimming.
Once you’re done with the tops of the hedges, you’ll want to:
- Step back and view the hedge for any excessive growth inside of the hedge
- Sweep or rake up after you’ve finished with your hedge trimming
- Once finished, be sure to clean and oil the blade to keep it in good condition for your next trim
- If you notice any issues with the blades or trimmer, make sure to have the unit repaired prior to your next trim
You can always go back and make any touchups necessary for your hedge at this time.
What Types of Bushes Can You Trim with a Hedge Trimmer?
Hedge trimmers can trim a variety of large and small bushes and hedges, including:
- Holly Bushes
- Holm Oak
- Yew Shrubs
- Yellow Ribbon
- Portuguese Laurel
- Western Red Cedar
- Red Robin Hedge
- Purple Beech
- Green Beech
- Common Laurel
Pro Tip: A general rule of thumb is to trim your shrubs outside of the dormant period. This is typically in the fall or late winter months.
Experts discourage trimming your flowering shrubs in early spring since you may cut off new growth needed for budding flowers or berries. A better time for a planned reshaping is after they are finished flowering for the year.
