These two get used interchangeably, and they mean quite different amounts of work. Asking for the wrong one is the commonest reason a tree quote surprises somebody.

The short version

  • Pruning is a broad term for targeted work — deadwooding, crown lifting, thinning, removing specific branches. It addresses a problem without changing the tree's overall size.
  • Reduction specifically makes the tree smaller, shortening branches back to suitable growth points across the whole crown.

The crown lift is the underrated one

If the complaint is that a tree has taken over the garden, a crown lift is very often the answer. Removing the lower branches returns the ground beneath to use, lets light in from the sides and opens up the view through — and it leaves a tree that looks better rather than cut about.

A lift costs less than a reduction and lasts far longer, because the raised line stays raised. The tree doesn't grow downwards.

Why reduction costs more

  • It's work across the whole crown rather than one area.
  • More climbing and more repositioning in the tree.
  • Far more material to cut, lower and chip.
  • More judgement per cut — every branch shortened to a suitable growth point.
  • Often rigging, where branches can't simply be dropped.
  • And a longer day, sometimes more than one.

The limit on reduction

Around a fifth to a quarter of the crown is a sensible maximum in one operation, less on a mature or stressed tree. Beyond that the tree responds with dense, weakly attached regrowth that becomes a bigger problem within five years than the original size was. Where more is genuinely needed, staging it over a couple of years is the honest approach.

What to say when you ring

Describe the problem, not the operation. "It's too tall" and "the kitchen's dark" and "I can't get the mower under it" all lead to different work at different prices — and one of them is usually much cheaper than the reduction people assume they need.

Not sure which you need?

Describe the problem rather than the operation and we'll tell you the smallest thing that fixes it.
