What we do
Crown thinning involves the careful, selective removal of a portion of smaller branches - primarily from the crown - to reduce canopy density without altering the overall shape or size of the tree. The result is a more open, airy structure that lets more light through, reduces wind resistance, and lowers the risk of storm damage. Our arborists follow BS3998 standards, removing no more than 30% of the crown in a single thinning to avoid stressing the tree.
Selective branch removal
We target congested, crossing, rubbing, and weakly attached branches throughout the crown.
Crown cleaning included
Dead, dying, and diseased wood is removed during the thinning process for improved tree health.
Improved light & airflow
Thinning opens up the canopy, allowing more natural light to reach your garden below.
Reduced wind resistance
A thinned crown lets wind pass through more easily, reducing the risk of limb failure during storms.
Pricing note: Cost depends on the tree's size, species, health, and how accessible it is - a tree in an open garden costs less to work on than one requiring sectional dismantling near a building. We always provide a free, no-obligation written quote after a site visit.
How it works
- 01
Tree assessment
We evaluate species, age, health and structure to plan the thinning safely and effectively.
- 02
Mark-up
Branches to be removed are marked so you can see exactly what's planned before work starts.
- 03
Thinning
Hand tools and pruning cuts are used for precise, clean removal with minimal bark damage.
- 04
Clean-up
Every twig and leaf is cleared, leaving your garden cleaner than we found it.
Frequently asked
- What's the difference between crown thinning and crown reduction?
- Thinning removes selected interior branches to let light through without changing the tree's overall size; reduction cuts back to lateral branches to reduce height and/or spread, typically by 15-30%.
- Why would I need crown thinning?
- To reduce wind resistance, let more light into the garden, or improve the health of a dense canopy.
- Will it damage the tree?
- No - done correctly, thinning is a recognised arboricultural technique that improves tree health when carried out to BS3998 standards.
- How often does a tree need thinning?
- Most species benefit from thinning every 3-5 years, depending on growth rate and species.
- Do you clear the arisings?
- Yes, all branches and debris are removed and the site left tidy.
- Is permission needed?
- Only if the tree has a TPO or is in a conservation area - we check this first.
