Reset, then maintain. The reset is the expensive part and you only want to do it once.

The Short Answer

Establish the species, decide the finished size, reduce it — in one season or two depending on severity — then keep it there with regular cutting.

The species decides what is possible, and it is the first thing to settle, not the last.

Step One — What Is It?

Step Two — Decide the Finished Size

Be specific, and be realistic. "Smaller" is not a brief. A height in feet or metres, a width, and whether the top matters, tells us what you actually want — and lets us tell you honestly whether the hedge will get there and stay looking like a hedge.

Aim slightly lower than your target. Whatever height you cut to, the hedge grows from there. Cutting to exactly the height you want means it is above that within a season and you are back where you started. Coming down a little further gives you room to maintain it at the height you actually wanted.

Step Four — The Reduction

Step Five — Keeping It That Way

Every restoration job we do started with one skipped year. Nobody plans to let a hedge go.

While You Are At It

A hedge restoration is a good moment to look at the rest of the boundary. If the fence behind it is failing, it is far easier to replace now, with the hedge cut back and the line accessible, than in three years when it has grown over again. Likewise a tree in or beside the hedge, or a clearance along the base — one visit, one set-up, one lot of waste, and the boundary is sorted for years rather than revisited annually.

FAQs

Overgrown Hedges in Keynsham — FAQs

How do I get an overgrown hedge back under control?

Establish the species, decide the finished size, reduce it in one season or two depending on severity, then keep it there with regular cutting.

Why does the species matter so much?

Because it decides what is possible. Yew, privet, beech and laurel take hard cutting well; leylandii and most conifers will not regrow from bare wood.

How low should I cut it?

Slightly below your target height. The hedge grows from wherever you cut, so cutting to exactly the height you want puts you back where you started within a season.

Should I do it in one go or two?

Moderately overgrown forgiving species can be done in one. Severely overgrown hedges are better staged — height one year, sides the next.

What if the base has gone bare?

It may not fill back in after years of shade. That is worth knowing before the work, and it is one of the situations where replacement is worth considering.

How do I stop it happening again?

Cut annually or twice yearly, keep a slight taper so light reaches the base, and never let it get wider at the top.

When should the reduction be done?

Late summer or early autumn for most, winter for deciduous hedges, and always with a check for nesting birds first.

Should I sort the fence behind it at the same time?

It is worth considering. With the hedge cut back the line is accessible, and doing both now is far easier than in three years.
