Not always — and that is worth saying by a company that sells pruning. There are jobs where paying a professional is clearly right, jobs where a gardener will do it better and cheaper, and a surprising number where the correct answer is to leave the tree alone.
When it is clearly worth it
- Anything that involves leaving the ground. Climbing, ladders, platforms. This is where the accidents happen and where insurance matters.
- Anything over something valuable. A conservatory, greenhouse, shed, fence or car changes a simple cut into a rigging job.
- Deadwood in a mature tree. Genuinely a safety issue, and identifying what is dead and what is dormant is not always obvious from below.
- A tree that has outgrown its space. Reduction done properly is skilled work; done badly it is topping.
- Anything on a protected tree. Getting the process wrong is a criminal offence rather than a mistake.
- Storm damage. Torn or hanging limbs are under tension and behave unpredictably when cut.
When a gardener will do it better and cheaper
- Small ornamental trees pruned from the ground.
- Fruit trees kept small, if they know what they are doing with fruit.
- Shrubs, however tree-like they have become.
- Hedges at any height, with the right equipment.
- Clearing brambles and undergrowth around the base.
When to leave it alone
This is the section most tree companies do not write, and it matters.
- A healthy young tree with room to grow. It does not need shaping. It needs time.
- A mature tree that is not causing a problem. Trees do not need routine pruning the way hedges need cutting. Intervention is for a reason.
- A tree simply because it is big. Size on its own is not a defect.
- A tree in autumn, for tidiness. The leaves are coming down anyway and will do so again next year.
- A veteran tree, beyond essential safety work. Old trees are damaged by well-meant tidying more often than by neglect.
The one job almost every mature tree does benefit from
Deadwooding, every three to five years. It removes the genuine risk, it changes the appearance more than people expect, it is the cheapest operation on the list, and it does not stress the tree at all — the wood being removed is already dead.
If you were going to do one thing to a mature garden tree and nothing else, that would be it.
Timing, if you are going ahead
| Work | Best time |
|---|---|
| Deadwooding | Any time — dead wood is easiest to spot in full leaf |
| Most broadleaf pruning | Late autumn to late winter, when dormant |
| Crown lift or thin | Winter, or summer if you want to judge the light |
| Plums, cherries, other stone fruit | Summer only — silver leaf risk in winter |
| Apples and pears | Winter |
| Birch, walnut, maple | Late summer — they bleed heavily if cut in spring |
The bleeding species catch people out. Birch and maple cut in early spring will run sap for weeks. It rarely does lasting harm but it looks alarming and it is easily avoided.
And the permission check
Whatever the scale, if the tree is in Leominster's conservation area it needs six weeks' notice to Herefordshire Council, and if it has a TPO it needs written consent. That applies to work on the tree rather than to how much you cut, so one branch counts.
