Can You Cut a Hedge Back Too Far?

Most gardeners know that the common practice of pruning is necessary to keep hedges in shape, but one question that always comes up is whether you can cut a hedge back too far.

There’s no doubt that it’s possible to end up taking too much off your hedge if you’re not careful. This could result in bare patches and in the worst cases, the hedge may completely die off.  To avoid this issue, never cut off more than one-third of good growth in one go.

Read on to explore the consequences of excessive hedge trimming and discover some best practices for pruning to ensure your hedge remains healthy.

Is It Possible To Clip Too Much Off Your Hedge?

The answer to this question is a definite yes. If you’re not careful it’s very easy to end up cutting a hedge back too far resulting in harmful consequences for its health and overall appearance. 

While hedges can tolerate a certain amount of pruning (some more than others) there are limits to how much you can trim off without causing it to die back. It’s important to understand these limits and exercise caution when pruning your hedge.

Resilience Of Different Hedge Types

Different hedge species have varying levels of resilience when it comes to pruning. Some hedges, like privet or leylandii, are more forgiving and can tolerate more severe cutting.

However, others, such as slow-growing conifers or certain flowering shrubs, may not recover as well if cut back too far. 

To avoid mistakes, find out what the specific characteristics of your hedge species are so that you know its tolerance to pruning.

What Happens If You Cut Your Hedge Back Too Far?

While trimming is essential for maintaining a hedge’s shape and promoting healthy growth, cutting a hedge back too far can have the opposite effect. 

Here are some of the main consequences of being overzealous with your trimming:

A Weakened Hedge

Excessive pruning can weaken the hedge’s overall structure by removing too many branches and foliage. This can lead to an imbalance between the root system and what’s left above ground, compromising the overall health and vigor of the hedge.

Stunted Growth

Like all plants, hedges rely on their abundant foliage to photosynthesize and generate energy for growth. If too much is removed in one go, the hedge may struggle to produce enough energy, resulting in stunted growth and a less pleasing overall appearance.

Bare Patches

Often one of the most obvious signs that a hedge has been clipped back too hard are obvious bare patches. This is because the branches have been taken too far back for new growth to sprout from what’s left.

Can A Hedge That’s Been Cut Too Far Back Recover?

If you have accidentally cut your hedge back too far, it’s not necessarily the end as most can often recover eventually and bare patches will naturally get filled in. 

Hedges are generally resilient and as long as the damage is not too great, can recover with proper care and time. 

To encourage new growth, make sure to provide adequate water and nutrients, but don’t overdo it. If possible, make sure the hedge gets lots of exposure to natural sunlight, and of course, avoid any further pruning until the hedge has had a chance to regrow. 

It may take some time to come back, possibly one or two growing seasons, so patience is key during the recovery process.

Best Practices For Hedge Pruning To Avoid Problems

Prevention is often better than cure, so to avoid the risks associated with cutting a hedge back too far, try following some of these simple trusted pruning practices. These guidelines will help you maintain a healthy hedge while achieving the desired shape and density:

Know Your Hedge

Understanding the growth habits of your particular hedge species is crucial for effective pruning. Some hedges, such as boxwoods, tolerate heavier and more frequent pruning, while others, like many conifers, may not respond well to extensive trimming. 

Only yew, hemlock, juniper, arborvitae, and false-cypress evergreen varieties can be hard pruned back to old wood successfully.

For the best results, research the specific hedge species you have and tailor your pruning techniques accordingly.

Gradual Reduction

Instead of drastically cutting back the hedge, opt for a gradual reduction using the ⅓ rule. 

Trim small portions at a time, removing no more than ⅓ of the wood, allowing the hedge to adjust and recover between pruning sessions. 

This approach ensures that the hedge’s growth and structure are maintained while reducing stress on the plant. It also makes it very difficult to cut back the hedge too much.

Timing is Key

The timing of pruning plays a significant role in the health of a hedge. For deciduous hedges, pruning is best done during their dormant period in late winter or early spring and always before new growth appears.

This should be the main cut of the year that reduces the size of the hedge. Lighter clippings during the summer months should only be to keep it tidy and for shaping.

Evergreen hedges are usually lightly pruned in late winter or early autumn.

Doing trimming work during these times helps to minimize stress on the plant, allowing it to recover much more quickly.

Use The Right Tools

Using the correct tools is essential for precise and clean cuts. It pays to invest in quality pruning shears, hedge trimmers, and saws designed specifically for the size and type of hedge you have. 

Tools with dull cutting blades can lead to ragged cuts, which are more susceptible to disease and slower to heal, so make sure you keep your equipment well-maintained.


By now you will know that while hedges benefit from regular pruning, it’s crucial to avoid cutting them back too far. Over-trimming can weaken the hedge, stunt its growth, and make it more susceptible to pests and diseases. 

By taking the time to understand your hedge type and employing some best pruning practices, you can greatly reduce the risk of mistakenly overdoing it.
