IN YOUR GARDEN
Question: What is a deco path, and how can I make one at home?
Answer: Decomposed granite, often called “deco”, is generally a light brown coloured filling material that is quite fine (about 3mm and less). If you can picture the finish on a clay tennis court, then that will give you a good idea as to what it looks like.
To lay a deco path you must first lay out the location of your path. To contain the decomposed granite, you must install a brick/paver header course or timber edge along your pathway.
The timber should be H5 rated for timber used in-ground (ask your supplier for advice) or plastic extruded materials for use in the ground. Then excavate the soil along your planned

path to a depth of 100mm and install your edging, anchoring the timber with stakes about every one metre.
The next step is to estimate how much decomposed granite you will need to fill the area between the edges. To make this easy on yourself, have a calculator available. Measure the length and width of your path and multiply these two numbers together. This will give you the square metreage of your path.
Multiply the total by the depth to work out the volume in cubic metres. This is the number that you will need to have delivered from your local supplier. Pro tip: don’t forget to add 10% extra to allow for compaction.
