When searching for the best garden edging for around trees there are many factors to consider.

Generally, edging for trees is in place to retain mulch, gravel and other loose materials. Very often edging around trees acts as a retaining edge to adjacent vehicular or pedestrian surfaces. This is especially so with materials such as tarmac or resin bound aggregates.

​Ultimately the best edging for trees will depend on if your trees are young or more established specimens. 

Best garden edging for young trees

​
If you have planted a young tree in your garden over the coming years its roots will expand. This will cause ground movement which will potentially distort and break through new edging.

​Therefore, the best garden edging for young trees will be flexible and not require deep installation. Even with a more flexible edging it would be advised to give the tree as much room to grow as possible. 

Flexiborder

​Flexiborder is a flexible garden edging made from recycled rubber. The edging comes in easy to install sections which can be curved to fit any shape.

​Each section can be secured with pegs which fit neatly into the edgings surface. As this edging sits closer to grounds surface it has less chance of being disturbed by tree roots.

Best garden edging for established trees

​​Established trees have already disrupted the ground to a large extent during their growing process.

This means you have less potential, future, movement from growing roots and expanding trunks. However established trees have very robust root structures around their base. This can make it almost impossible to excavate around or install materials to their circumference.

Consequently, the best edging for around established trees is heavier masonry installations. This includes materials such as brick and block edgings.

For thin and curved edgings timber gravel boards are the best for around established trees. This is because square slots can be cut out to accommodate roots where necessary.

Gravel Boards

​
Gravel boards are treated, flexible, timber boards traditionally used in fencing. As a timber material these boards can be cut and worked in a number of ways.

​This is very advantageous when submerging edging around the perimeter of established trees. Slots can be cut out to avoid large roots when installing as edging. Gravel boards are also very flexible making them perfect for forming organic shapes. 
​

Bricks Edging

​
Laying brick edging can be a little labour intensive and expensive. However this type of edging provides a robust edge that will last the test of time.

Brick edging provides a broad width which reduces the risk of bark and gravels scattering. It can also provide the perfect mowing edge for lawns.

Block Edging 

​
Block paving has very much the same credentials of brick edging. Around established trees block edging can form a robust retainer to mulch and aggregates.

As blocks come in a wide variety of styles and materials they provide a lot of choice. The combined weight of the blocks, aggregates and mortar results in a sturdy, edging solution for around trees.
