My Hedge Is Taking Up Too Much of My Garden – What Are My Options?

Width is harder to fix than height, and on some species it cannot be fixed at all. Worth knowing which yours is.

The Short Answer

Four options: narrow it, reduce it in stages, replace it with something more suitable, or remove it and fence.

Which is available depends on the species. A hedge that regrows from old wood can be narrowed substantially. A conifer that has grown past its green cannot be narrowed at all without leaving a brown wall.

How Much Space a Hedge Actually Takes

On a small or narrow garden this can add up to a surprising proportion of the useable space — which is usually why people start asking the question.

Option One — Narrow It

Option Two — Reduce Height and Width Together

Where the hedge is both too tall and too wide, staging it makes a real difference. Height one year, one face the next, the other face the year after. Slower and more expensive across three visits, but it produces a hedge rather than a scarred remnant — and on a hedge that has been there thirty years, three years is not a long timescale.

Option Three — Replace

ConsiderationReality
CostHigher than reducing
Time to screen againThree to five years
Space recoveredThe most of any option
ChoiceYou pick a species that suits the space
Root removalSubstantial work; soil will be exhausted
DisruptionConsiderable, but once
SuitsConifers past their green; wrong plant for the position

Replacement is the honest answer where the current hedge is simply the wrong plant. A leylandii planted as a quick screen in a small garden will always want to be twenty metres tall and two metres wide — reducing it is a permanent commitment to fighting it. Yew, hornbeam or a native mix in the same position needs a fraction of the maintenance and stays where you put it.

Option Four — Remove and Fence

A mature hedge in a small garden is often taking up a tenth of the plot. It is worth measuring before deciding it is fine.

FAQs

Wide Hedges in Hanham — FAQs

Can a hedge be narrowed?

On species that reshoot from old wood — yew, privet, beech, hornbeam, laurel, hawthorn — yes, usually one face at a time across two seasons. Conifers generally cannot be narrowed.

How much space does a mature hedge take?

Often a metre or more of depth, plus root spread, a dry shadow where little grows, and access space to cut it. In a small garden that can be a tenth of the plot.

Should I narrow both sides at once?

Better not, on a severe reduction. One face, then the other the following year, gives the hedge time to respond.

When is replacement the better option?

When the current hedge is the wrong plant for the space — a leylandii in a small garden will always want to be twenty metres tall, and reducing it is a permanent commitment.

What if I remove it and fence instead?

You recover the most space immediately and lose the maintenance, but also the screening height, wildlife value and softness. A fence with planting in front is a middle path.

How long before a new hedge screens?

Three to five years, depending on species and planting size.

Will narrowing look bad at first?

The cut face will be bare for a season on most species. Deciduous hedges recover quickly; conifers may not recover at all.

Do I need to tell my neighbour?

It is their boundary too, and access to the far face is usually needed at some stage. Worth a conversation first.
