Crown Reduction

The reduction of the complete outline dimension of the canopy, from the tips of the branches to suitable internal branches. The diameter of the remaining branch should not be less than one third of that removed. After a crown reduction the tree should retain an overall appearance typical for the species or variety of the tree concerned.

Crown Thinning

The removal of a proportion of the small, live woody growth to reduce the density of the foliage throughout the canopy. This operation is usually specified as a percentage. The aim is to produce an evenly distributed canopy of foliage on a well-structured, balanced and sound skeleton of limbs and branches, typical for the species or variety of tree concerned.

Crown Lifting

To increase the distance between the ground and the lower branches of the crown of a tree by removing parts of branches or whole branches, providing the wounds left do not exceed 50mm. This is common practice where trees overhang roads or footpaths.


Defined as the cutting back of all branches of a tree back to the main stem at a specified height above the ground. The result is a production of a quantity of vigorous shoots usually from close to the cuts, but in some species (e.g. Lime) the shoots may be throughout the length of the trunk. Where pollarding has taken place previously the new pollard should generally be just above the previous pollard points, unless decay is considered so extensive that re-growth shoots would be potentially dangerous.

Crown Cleaning

The removal of weak, diseased and dead branches or limbs throughout the crown of the tree as necessary to prevent them being a nuisance or causing damage if they were to shed.

Stump Grinding

In order to remove a stump after felling a tree to ground level it is necessary to use a stump grinder as this is the quickest and most effective method to obtain a stump-free finish.

Cable Bracing

Flexible bracing is a technique used to provide additional support for branch and stem unions showing indicative signs of inherent weakness e.g. tight forks or heavy lateral branches. Braces are designed to assist the tree's mechanics in extreme conditions such as strong winds. Heartwood Tree Surgeons Ltd has a vast experience in cable bracing and uses modern 'cobra' cable bracing products .
