Tree pruning explained: crown reduction, crown lift and deadwood

Pick the problem first, then the cut

When people ring about a tree they often ask for it to be topped or cut back hard. Usually what they mean is that it blocks light, hangs over the house, drops branches or has simply grown bigger than expected. Each of those problems has a different answer, and naming the problem gets a better result than naming a cut.

Tree surgery on our side covers reductions, crown management, dangerous limb removal and felling. On a visit Craig will explain which option suits the tree, the property and the people nearby, and write the work down in proper terms so you know exactly what you are paying for.

Crown lift: more light and headroom underneath

Lifting the crown means removing the lowest branches so there is clear space beneath the canopy. It is the go to answer when a tree shades a lawn, scrapes the roof of a van, overhangs a path or stops you walking under it. The overall height does not change, so the tree still looks like itself from a distance.

Lifting is usually specified as a height above ground, which is easy to agree and easy to check afterwards.

Crown reduction: a smaller tree of the same shape

A reduction shortens the outer branches all round so the tree is lower and narrower. Done properly, cuts are made back to suitable side branches rather than chopping every limb at the same point, so the tree keeps a natural outline and grows back in a balanced way. It suits trees that have outgrown the space, sit close to buildings or catch the wind badly.

It is not the same as topping. Topping leaves large stubs that sprout dense, weakly attached regrowth, which becomes a bigger problem a few years later. That is widely understood among tree surgeons, and it is why we steer people towards a measured reduction.

Crown thinning: letting air and light through

Thinning removes a proportion of the smaller inner branches without changing the outline much. The tree looks lighter, more dappled light reaches the ground and wind moves through the canopy more easily. It is a subtler job than a reduction and suits trees that are the right size but too dense.

Deadwood and dangerous limbs

Dead branches are brittle, they can fall without warning, and they are often the first thing to come down in a storm. Removing deadwood is a safety job and is frequently done alongside a lift or a reduction on an older tree. Where a limb is split, hung up or cracked, it may need attention straight away, and that is when the 24/7 emergency line exists.

• Dead or snapped limbs over paths, drives or roofs
• Branches hung up in the canopy after wind
• Splits or cracks where a limb joins the trunk

When pruning is not the answer

Some trees are in the wrong place, are dying or have a structural fault that pruning cannot fix. In those cases felling may be the honest recommendation, with the stump then left, ground or dug out as a separate decision. Before any work on a tree that might be protected, whether by a tree preservation order or because it stands in a conservation area, the right permission needs to be in place first.

Getting the right work quoted

Send a photo of the whole tree and a closer one of the problem area, say what bothers you about it, and mention anything nearby such as a greenhouse, power line or neighbour's garage. From that Craig can suggest the most suitable type of crown work and confirm it on site.
