Assess the Tree and Choose Materials:

Before starting the project, evaluate the tree’s health and consider the impact of a retaining wall on its root system. Consult an arborist if necessary to ensure the project will not harm the tree. Next, select the materials for your retaining wall, such as concrete blocks, timber sleepers, or natural stone. Consider factors such as durability, aesthetics, and cost when making your decision.

Determine the Wall Layout:

Measure the circumference of the tree and add at least one metre to provide sufficient space for the tree’s root system to thrive. Mark the outer boundary of the retaining wall using wooden stakes and string or spray paint. Ensure the layout is circular or curved to accommodate the tree’s growth.

Prepare the Ground:

Clear the area within the marked boundary of any grass, weeds, or debris. Dig a trench around the tree, approximately 200mm deep and 300mm wide, following the marked layout. Ensure the trench is level to create a stable foundation for the retaining wall.

Install the Drainage System:

A proper drainage system is crucial to prevent waterlogging and maintain the health of the tree. Place a layer of landscape fabric in the trench, followed by a 100mm layer of crushed rock or gravel. Install a perforated drainage pipe on top of the gravel layer, ensuring it slopes slightly away from the tree to direct water away from the roots. Cover the pipe with another layer of gravel and fold the landscape fabric over the top.

Construct the Retaining Wall:

Begin constructing the retaining wall by placing the first row of blocks, sleepers, or stones in the trench. Ensure each piece is level and tightly fitted against the next. For added stability, use a construction adhesive or mortar to secure the materials together. Continue building the wall in layers, staggering the joints between each row to create a stronger structure. The height of the wall will depend on the desired look and the slope of the surrounding landscape.

Backfill and Finish:

Once the retaining wall is complete, backfill the area between the wall and the tree with a well-draining soil mix, ensuring not to bury the tree’s trunk or damage the roots. Compact the soil gently as you go to eliminate air pockets and provide a stable base for planting.

Plant and Landscape:

Complete the project by planting suitable plants or ground cover within the retaining wall. Choose species that are compatible with the tree and the local climate. Add mulch around the plants to help retain moisture and suppress weeds.

Building a retaining wall around a tree can be an excellent addition to your landscape, providing both functionality and aesthetic appeal.
