What’s the best way to install CORE Edge in hard ground?

The anchor pins on CORE Edge are highly durable and can be driven into most firm ground using a wooden mallet or a block of wood. If the ground is particularly hard, it’s best to loosen it first with a garden fork or pickaxe. Once the edging is installed, firm the soil back against it by treading it down. If the edging is intended to sit above ground level, for example, to create a raised border, the galvanised stabilising pins may be required for additional support.
