Add a touch of rustic charm to your garden by using DIY driftwood wall art as garden edging. Start by collecting long and sturdy driftwood pieces that are suitable for creating a border. Clear the area where you want to install the driftwood edging and dig a shallow trench. Place the driftwood pieces along the trench, making sure they are securely embedded in the ground. Use a rubber mallet to gently tap the driftwood into place if needed. Once the driftwood is installed, backfill the trench with soil and pack it down firmly. The driftwood edging will not only define the borders of your garden but also add a natural and organic element to the overall design.
