To cover pond liner edges, start by trimming any excess liner to leave severak inches of material around the entire pond perimeter. This extra material is used to anchor the liner and keep it from moving. You can bury the liner in an anchor trench or use decorative stones, rocks, or boulders to line the edges, placing them closely together to create a natural appearance while preventing the liner from stretching or slipping..
Soil, mulch, and smooth gravel and river rocks can also be used to create a gradual transition from the pond to the surrounding landscape for a more seamless look. Native aquatic plants or grasses planted along the edges will disguise the liner and enhance the pond's aesthetic appeal. Ensure that the plants are suited for the moisture levels near the pond's edge to promote healthy growth.
