Put in demarcation stakes to mark the path of the edging.
Install the edging and secure its position using the planted stakes. Gently push it into the ground.
Pour in the soil to fix the edging in its position. It will be more stable during filling.
Fill in the soil. Leave 4-5 cm for filling with gravel or stone aggregate.
Place the geotextile and remove anchoring elements.
Fill in and leave a 1-2cm gap between the fill and the upper edge of the garden edging.
