Using sedum mat to hide a pond liner

How to edge a pond – If you’re looking to hide the edges of your pond, a sedum mat is a great place to start. Sedum mat is most often associated with green roofing, but it also makes a fabulous edging for a pond.

The edge of a pond liner or the “lip” around a preformed pond can look quite unsightly, especially if you are trying to create a natural-looking water feature.

So, edging a pond with sedum matting can enhance its aesthetic appeal while also providing ecological benefits. Sedum, a hardy succulent, is well-suited for pond edges because of its ability to thrive in moist environments and its low maintenance requirements. Here’s a step-by-step guide to edging your pond with sedum matting:

  1. Assess your pond area:

    Before starting, assess the perimeter of your pond to determine the amount of sedum matting you’ll need. Measure the length and width of the area you plan to edge.

  2. Select sedum varieties:

    Choose sedum varieties that are suitable for your climate and soil conditions. Opt for low-growing varieties that spread easily and can withstand occasional moisture.

  3. Prepare the soil:

    Clear the area around the pond of any debris, rocks, or weeds. Loosen the soil to a depth of a few inches to ensure good root penetration.

  4. Install sedum matting:

    Lay the sedum matting along the edge of the pond, ensuring it covers the soil completely. Overlap the edges of the matting to prevent gaps where weeds can grow through.

  5. Secure the Matting:

    Use landscaping pins or stakes to secure the sedum matting in place. Place the pins every few feet along the edge to prevent the matting from shifting.

  6. Water the matting:

    After installation, thoroughly water the sedum matting to help it establish roots. Keep the matting moist, but not waterlogged, during the initial establishment period.

  7. Monitor and maintain:

    Regularly check the sedum matting for weeds or signs of dryness. Remove any weeds that may appear and water the matting during dry spells.

  8. Encourage growth:

    To promote healthy growth, fertilize the sedum matting with a balanced fertilizer once or twice a year, following package instructions.

  9. Trim as necessary:

    Trim the sedum matting as needed to maintain its shape and prevent it from encroaching on the pond. Use scissors or pruning shears to trim away any overgrown or dead foliage.

As an example – at the 2013 Letchworth Food and Garden Show, Maxine Tricker designed a show garden using a preformed pond disguised with Enviromat sedum matting. For this project, she was assisted by Noodles, the Hungarian Puli.


Noodles checks the quality of the sedum mat.  She’s  particularly impressed by the texture.
