Project Overview

Installing garden edging around a tree is a simple D.I.Y. project that will keep grass and its roots away from your tree and help it to grow. This easy to follow guide tells you what tools and equipment you need and how to secure the edging.

Continue to Step-by-step instructions.

Step by Step Instructions

1 Remove the concrete ring from around the tree
2 Dig around the tree
3 Roll-out and cut the garden edging
4 Secure the edging
5 Backfill and add mulch to the tree
  • Step 1. Remove the concrete ring from around the tree

    Remove the concrete tree ring from around the tree by putting the shovel under it and levering it up. Ask someone to help you lift the ring over the tree. If the tree is too tall to lift the concrete ring over, use a sledge hammer to break it into smaller pieces.

  • Step 2. Dig around the tree

    Use the shovel to create a border by digging up the grass surrounding the tree. How far you dig up the grass away from the tree will determine the length of edging you’ll need. Dig a trench for the plastic garden edging to sit in. 
  • Step 3. Roll-out and cut the garden edging

    Take the roll of garden edging and lay it in the trench you dug around the tree. Let the edging overlap where it meets by about 10 centimetres. This is where the edging will be joined. Mark where the end of the overlap is and use a hacksaw to cut the edging.
  • Step 4. Secure the edging

    Place a peg on the inside of the garden edging, where it overlaps. Use a hammer to drive the plastic peg into the ground. Make sure that the top of the peg’s overhanging lip is sitting on the garden edging. Continue hammering in the pegs, so that they’re evenly spaced around the garden edging and it is secure.

  • Step 5. Backfill and add mulch to the tree

    After hammering in the pegs, use the shovel to backfill the soil into the trench the garden edging is sitting in. Do this on the inside and outside of the edging. This will allow the grass to grow right up to, but not over the edging. Add a healthy layer of mulch around the tree, this will not only help the tree to grow but will also make the project look more professional.

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions which came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings team member.
