A hedge dominates a garden in one of three ways, and the answer is different for each. Working out which one you have is the useful first step, because the options run from cheap to expensive and people often assume the expensive one.

Which kind is it?

Simply being shaggyA proper trim, faces includedLowest
The last row is more common than people expect. A hedge that has not been cut for two or three years looks like it has taken over when it has really just gone shapeless. A proper cut — faces as well as top, back to a line — frequently settles it.

Width is usually the real problem

When people say a hedge dominates, they mostly mean it has taken their ground. And that is almost always the width rather than the height, because the width is the part nobody watches.

A hedge cut only on top puts on a few inches of width a year. Over fifteen years that is a foot or more on each face — two feet of border gone. It is invisible year to year because it never changes much between one summer and the next, and the hedge always looks freshly cut.

Height changes how enclosed a garden feels. Width changes how big it is.

What you can get back

Taking a foot off each face of a fifteen-metre boundary hedge returns around thirty square feet of border. In a small Ludlow garden that is a meaningful proportion of the plot.

It usually improves what is already there, too. The strip immediately in front of an overgrown hedge is the worst ground in most gardens — dry, shaded and full of hedge roots. Pulling the hedge back gives the plants in front of it light and room.

Worth knowing that the roots do not retreat with the foliage, so the reclaimed strip stays somewhat dry. Anything planted close to a hedge wants to be reasonably tough and watered well in its first year.

How far you can go

On beech, hornbeam, yew, laurel, privet, hawthorn or holly — right back to the main framework. These regenerate from old wood, look bare for a season and then thicken up better than before.

On Leylandii and most other conifers — only as far as the green growth goes. Push a hand into each face and find how deep the green is before agreeing anything. The shaded side usually has less than the sunny one, and it is the side that limits what is possible.

Stopping it happening again

This matters more than the reduction itself and it costs nothing.

  • Cut to the same line every time — the line it was cut to last time, not wherever the growth has reached. That single habit keeps a hedge the same size for decades.
  • Do the faces every time, not just the top. Topping alone is what caused the problem.
  • Put a batter on it — slightly wider at the base than the top, so light reaches the bottom and the base stays green.
  • Cut annually. Every skipped year, the next cut starts from further out.

When replacement is the honest answer

  • A conifer hedge with almost no green left, that cannot usefully be reduced.
  • A hedge so wide it has taken a significant part of a small garden and cannot come back far enough.
  • A hedge in genuinely poor condition — dying back or gappy throughout.
  • A boundary being re-fenced anyway as part of wider work.

If that is the conclusion, beech, hornbeam, yew or laurel all recover from hard cutting, so the same problem does not recur in twenty years. Another conifer gives you an identical situation on a delay. And a fence is generally limited to two metres, so it will not replace the screening a tall hedge was giving you.

One check before anything comes out

A hedge cannot carry a Tree Preservation Order, but a tree grown up within one can — and older boundaries frequently have ash, sycamore or holly seeded into them. Ludlow's conservation area is extensive, so a tree in a hedge there needs six weeks' written notice to Shropshire Council above 75mm stem diameter, measured 1.5m up. A TPO tree needs written consent at any size.
