Your Guide to Pruning Hedges

Shaping plants into a formal hedge can be a wonderful way to create privacy or a backdrop in your garden, but it requires some maintenance to keep them looking good for the long term. Here are some tips on pruning hedges along with the tools to use, proper timing, and a few helpful tips.

your guide to pruning hedges

Pruning hedges is very different than pruning trees. While when pruning trees and shrubs I always suggest following the natural lines of the plant, hedges and topiaries are the exception. Because growing a number of plants together in a decorative shape fights against how the plants would naturally grow, it’s best to plan the hedge well and then keep up with the pruning during its lifetime.

Choose the Right Hedging Plants

First things first, make sure you’re growing a hedge with plants that respond well to being grown as a hedge. Hedging plants can be deciduous or evergreen; broad-leaf or conifers. The thing they all have in common is how they respond to heading cuts: by filling out.

Plants suitable for hedging will be noted “hedging plants” or “topiaries” on their plant labels. Some popular varieties are boxwood (Buxus), privet (Ligustrum), yew (Taxus), laurel (Laurus nobilis), barberry (Berberis), quince (Cydonia oblonga), Euonymous, holly (Ilex), juniper (Juniperus), Arborvitae, cedar (Cedrus), Pyracantha, and Viburnum.

Start Them Young

Plants that are trained from a very young age make for the best hedge. In the first two years, the plants will be cut back six to eight inches to encourage branching close to the core of the plant. In the third year, the hedge can be shaped. This will determine its structure as it grows to its final mature size. If the hedge isn’t shaped until after the plants have grown to their full size, there won’t be enough branching at the base to create a full hedge.

When the hedge is at the size and shape that you like it, the best way to maintain the look is to trim it frequently.

When to Prune Your Hedge

As a general rule, prune the hedge before the new growth blocks the sun from the lower leaves. As the lower leaves lose sunlight they begin to die off in favor of the new growth.

Some evergreens are quite quick growing and need to be pruned every four to six weeks in the growing season, while others may grow a bit slower and only need to be pruned once. The best way to determine how often to prune is to watch the growth and trim it before it begins to shade the leaves below.

Hedge Pruning Tools

Many people use electric trimmers to prune a hedge but hand tools give you a cleaner cut and less damage to the branches. An electric hedging tool will tear and rip the branches leaving uneven cuts, while a hand tool leaves clean cuts that heal nicely and keep the plant healthy. Uneven cuts stress out the plant and are an open invitation for disease. Plus, there are many benefits to silent gardening as I previously wrote about in this post on Silent Lawn Care.

Preparing to Prune

Before trimming your hedge, clear your workspace and remember it’s always best to wear safety goggles and gloves.  Additionally, you may wish to drop a tarp below your hedge to catch your clippings in order to make cleanup easier.

It can be challenging to maintain a uniform shape when pruning a formal hedge. It helps to use guidelines as reference points on where to cut and how much. You can achieve this by running a string line tied tautly between stakes along the bottom of the hedge to guide how much of the side to remove and running a string line along the top to guide how much of the top to remove.

using a string line

Clean and sharpen your tools before pruning. Keep a bucket of soapy water and a rag on hand to clean your tools in between plants if you are pruning multiple hedges. As cuts open up the wood to disease, it’s important to make sure you are keeping your tools clean.

Manual Hedging Tools

PowerGear2 Pruners

 

prunersUse PowerGear2 Pruners to clear out any dead, dying, or diseased wood. The branches of a hedge are thick and woody, so you will want a powerful set of pruners to make quick work of the project. PowerGear2 Pruners give you more power than standard pruners so you can cut thicker branches and use less effort.

POWER TOOTH® Softgrip® Folding Saw (7″)

guide to pruning hedges

Keep a POWER TOOTH® Softgrip® Folding Saw (7″) handy for cutting branches thicker than 3/4″ in diameter for PowerGear2 Pruners and 5/8” for standard pruners. The saw blades are incredibly sharp, so it’s best to keep it in the folded position until you need to make a cut. The good news is that it will cut the branch easily with those sharp teeth!

PowerGear2™ Hedge Shears (23″)

hedge pruning tips and tricks

The PowerGear2™ Hedge Shears are smaller and lighter than standard hedge shears and yet more powerful. This makes them very easy to use, especially if you are pruning a large hedge.

Start pruning at the bottom of the hedge and work your way up so that cut branches and leaves at the top can freely fall to the ground.

Shear the hedge in shallow layers to make sure you don’t accidentally expose bald spots in some of the shrubs. Position the blades at a right angle to the branches to get the cleanest cut. Be sure not to twist the branches or approach them at an odd angle, as they won’t cut cleanly.

If you use a string line, ensure that your shears are consistently parallel with your shrub to stay on track.  If you tend to go off line a little bit it’s not going to make a huge difference; the plant will grow and fill in the gaps. With practice, it will become second nature.

Power-Lever® Extendable Hedge Shears (25″–33″) 

prune hedges like a pro

If you have a high hedge, then the Power-Lever® Extendable Hedge Shears will make the job a whole lot easier! Extendable handles make high, hard-to-reach or awkward cuts easier. If the hedge is short enough, you don’t have to climb up and down a ladder a bunch of times. If the hedge is taller, you still benefit from telescoping shears because you can use a shorter and more stable ladder. This is particularly helpful in small spaces.

Power-Lever® Grass Shears

grass shears

After pruning your hedge, go back with Power-Lever® Grass Shears and PowerGear2 Pruners to clean up any of the little bits that pop up after shearing is complete and to remove any leafless branches that protrude. Grass shears are my go-to tool for finishing work. You can see how great they work on decorative topiaries here.

Repairing Damaged Hedges

If your hedge has become overgrown, or is bare or dying back, it can be hard to repair. Evergreen plants will not generally fill back in; it is better to replace the individual plants. Deciduous hedges will come back over time if carefully pruned when dormant.  Either way, it’s best to keep up with the job throughout the season and maintain your hedge properly than to fix problems once they arise.

More on Pruning

Pruning is just about one of my favorite things to do out in the garden. I love to shape trees and bring out their natural beauty. There are many people who are quite afraid of pruning and these guides are a great way to take the fear out of it!

    I have a very old privet hedge that I am working hard to rejuvenate. It stands between my house and the sidewalk so it is quite visible. It was covered in vines and even young trees grew within the mess. I’ve done my best to pull out the invaders. I pruned the dead wood and pruned to stimulate new growth. I am left with mostly bare sticks. Is there hope for my hedge or do I give up on it and replace? If I keep it, how can I control the aggresive mix of vines that continue to attack it each year?

    Fiskers are Awesome tools! How great to have a giveaway. Thank you! Even if I don’t win them…. One thing my Pa always told me was that one reason hedges start looking bad at the base is because people trim them as close to vertical as they can. He taught me to look at trees and there is a reason they taper – to get sunlight…said that hedges should be wider at the bottom and narrower at the top. Doesn’t have to be very noticeable – just a bit wider at the bottom. He was a landscaper/horticulturist and he did really know his stuff!

    Those hedge shears would be WONDERFUL as my yard is surrounded by a type of honeysuckle hedge that grows like wildfire. It is interspersed with wild grapevine, and at one point, was hanging over my four-foot chainlink fence and taking up almost four feet of my yard space. You see, the hedge is in my neighbors’ yards, not mine, and is a bear for me to maintain, because they do not! I am very familiar with Fiskars’ tools and their quality, and could use a good set of quality shears to make this chore a little easier! :)

    We have a dwarf apple tree and have never trimmed it; needless to say, it is really tall (5 years old). Okay, if we prune it, when is the best time of the year. We have heard early Spring and also in the Fall, which is the reason we haven’t pruned it yet. We purchased another dwarf apple tree and have only had it 2 years, so it is still pretty small. Have never pruned before, so am a little anxious. Have seen the different discussions on this website re: pruning.

    I am looking for advice on how to prune back our VERY unruly lilac bush. We let it get too big because we loved all the blooms, but now it is a mess. We cut some of the older thicker branches out, but it is all saggy now. Wondering if we should cut it all the way down to a few feet tall to let it start anew?

    When pruning, think of the Pyramids – wider at the base than the top to allow sunlight to hit all leaves. Stay away from unnatural shapes when pruning. Balls, cubes and other odd shapes are not found in nature for a good reason.
