What Is Crown Raising and When Is It Needed?

What Does Crown Raising Mean?

Crown raising involves selectively removing some of the lowest branches from a tree's crown.

The aim is to increase the distance between ground level and the lowest part of the canopy.

Rather than reducing the overall height of the tree, crown raising concentrates on the lower branches. This makes it particularly useful where a healthy tree is simply taking up too much space at ground level.

Why Is Crown Raising Carried Out?

There are several reasons why crown raising may be recommended.

It can be used to:

• Improve clearance over paths and pavements

• Provide more room above driveways

• Prevent low branches interfering with vehicles

• Improve access around gardens

• Increase clearance from buildings, fences and structures

• Improve visibility beneath a tree

• Allow more usable space underneath the canopy

• Reduce interference with lawns and garden areas

For many mature trees, crown raising can solve a clearance problem without significantly changing the overall appearance of the tree.

Crown Raising Over Driveways and Paths

Low branches can become particularly inconvenient when they extend across driveways, entrances or frequently used paths.

As branches grow larger and heavier, their clearance can gradually decrease.

Carefully removing or shortening selected lower branches can create considerably more room while leaving the upper canopy intact.

This can be especially useful where cars, vans or garden machinery regularly pass underneath a tree.

Crown Raising in Gardens

Crown raising can also make a garden feel much more open.

Large trees sometimes have lower branches extending across lawns, patios or other parts of the garden. Removing selected branches can provide more headroom and make the space beneath the tree easier to use.

It may also allow additional light beneath the lower canopy, although crown raising should not be confused with crown thinning, which is specifically intended to selectively reduce branch density throughout the crown.

Does Crown Raising Reduce the Height of a Tree?

No.

Crown raising normally has little or no effect on the overall height of the tree.

If the objective is to reduce the height or overall spread of a tree, crown reduction may be more appropriate.

If the objective is to selectively reduce the density of branches throughout the canopy, crown thinning may be considered instead.

These are different pruning techniques and should be chosen according to the tree, its condition and the reason for carrying out the work.

Can You Crown Raise Any Tree?

Not every tree should be treated in exactly the same way.

The species, age, condition and structure of the tree all need to be considered before significant branches are removed.

Removing too many lower branches can negatively affect the appearance and structure of a tree. Large pruning wounds can also take considerably longer for a tree to occlude than smaller cuts.

For mature trees in particular, it is usually better to take a considered approach rather than removing large numbers of substantial branches unnecessarily.

How Much of the Crown Should Be Removed?

There isn't one correct amount for every tree.

Good crown raising is selective.

The aim should be to achieve the required clearance while retaining an appropriate amount of live crown and maintaining a balanced structure.

Sometimes only one or two problematic branches need attention. Other trees may require several carefully selected branches to be removed or reduced.

Is Crown Raising the Same as Crown Reduction?

No.

Crown raising increases clearance beneath the canopy by dealing with lower branches.

Crown reduction reduces the overall height and/or spread of the canopy.

Crown thinning selectively removes branches throughout the crown to reduce its density while generally retaining its overall size and shape.

Understanding the difference is important because unnecessary pruning can permanently alter a mature tree.

Professional Crown Raising

Tree pruning should be planned around the individual tree rather than simply removing every branch below a particular height.

At Dragonfly Tree & Garden Services, we assess the tree and the reason additional clearance is required before recommending an appropriate approach.

With 39 years of industry experience, we provide practical tree surgery advice and professional tree work throughout Cannock, Lichfield, Rugeley, Penkridge and surrounding areas.
