Pond liners are a practical necessity, but they can detract from the natural, serene aesthetic of a garden pond. Luckily, there are several ways to hide hard plastic pond liners. One option is to use gravel and rocks to conceal the liner, creating a natural, jumbled effect. Another option is to use plants, such as creeping jenny or charlie, which can grow and cascade over the liner, effectively hiding it from view. For vertical pond walls, pond fabric, gravel, sand, and strategically placed water plants can be used to hide the liner. Additionally, products like Rock on a Roll or synthetic rock veneers can be used to create a more natural-looking liner. With some creativity and careful placement, it is possible to achieve a beautiful and seamless pond design that hides the hard plastic pond liner from view.

What You'll Learn

Use gravel, rocks, and boulders to hide the liner
One of the easiest ways to hide a pond liner is to use gravel, rocks, and boulders. If your pond has gently sloping sides, you can use gravel or small pebbles to create a beach that leads into the deeper part of the pond. This type of pond is ideal for attracting wildlife like frogs and birds.
Another way to hide the pond liner is to create a small shelf around the entire edge of the pond and place a layer of square or rectangle-shaped rocks on it. Once the shelf rocks are in place, you can add edging rocks on top. Flagstone is a popular edging rock that is commonly used in landscaping. You can also use flat or textured stones, overlapping them slightly and leaving gaps that can be filled with soil and plants. For increased stability, use mortar to fix the stones in place.
If you want to avoid using a lot of rocks, you can use a product called Rock-on-a-Roll, which has the look and texture of natural stone. It is flexible and can conform to any shape, allowing you to hide the pond liner without piling up boulders. Rock-on-a-Roll is lightweight and takes up almost no space inside the pond.
When placing rocks on the pond liner, be careful not to tear it. If you damage the liner, there are patch kits available to repair any small rips or tears. Remember to wash the rocks thoroughly before placing them around the pond.

Apply silicone to attach rocks to the pond's edge
Silicone caulk is often recommended by pond installers for sealing rocks to the pond liner and to each other. It is waterproof and non-toxic, but it may not be able to hold large rocks together. Here is a step-by-step guide on how to apply silicone to attach rocks to the pond's edge:
- Layout the rocks: Before applying any adhesive, it is important to plan and lay out the rocks in the desired arrangement. This will help ensure that the rocks are attached securely and aesthetically.
- Prepare the silicone: Read the instructions on the silicone caulk carefully and prepare the mixture accordingly. Ensure that you are working with a waterproof and non-toxic adhesive, especially if you plan to have fish in your pond.
- Apply the silicone: Using a caulking gun or adhesive applicator, apply a generous amount of silicone to the back of each rock. Press the rocks firmly onto the pond edge, holding them in place for a few seconds to ensure a strong bond.
- Fill gaps: If there are any gaps between the rocks or between the rocks and the pond liner, use the silicone to fill and seal these spaces. This will help create a smooth and natural-looking finish.
- Allow for curing: Follow the manufacturer's instructions for curing time. Do not disturb the rocks or attempt to move them during this period to ensure that the silicone sets properly.
- Final touches: Once the silicone has cured, inspect the rocks to ensure they are securely attached. You can trim any excess adhesive that may be visible using a knife or a saw.
It is important to note that while silicone caulk is a common choice, it may not be suitable for all rock types and sizes. For larger rocks or more complex arrangements, consider using alternative adhesives like two-part epoxy glue, construction adhesive, cyanoacrylate glue, or black waterfall foam. These alternatives offer stronger bonding but may require more careful application and consideration of the rock's characteristics.

Use pond fabric and moss to conceal the liner
Pond fabric and moss can be used together to conceal a pond liner. Pond fabric, also known as pond underlay, is a non-woven geotextile fabric that serves as a protective layer between the pond liner and the ground. It helps to prevent tears and punctures in the liner, as well as providing a surface for plants to root and grow.
To use pond fabric and moss together to conceal your pond liner, follow these steps:
- Prepare the pond: Ensure that your pond has been properly excavated and that you have created a flat shelf of soil about 8 to 12 inches below the intended surface of the pond. This shelf will provide support for the pond liner and the rocks or flagstones that will be used to conceal it.
- Install the pond liner: Place the pond liner over the prepared shelf, ensuring that it fits snugly and securely.
- Add pond fabric: Cut the pond fabric into pieces that are slightly larger than the pond liner. Lay the pieces of pond fabric over the liner, ensuring that the edges of the fabric extend beyond the edges of the liner. You may need to use multiple pieces of fabric to fully cover the liner.
- Secure the pond fabric: Use rocks, gravel, or soil to secure the edges of the pond fabric. Bury the edges under the soil or tuck them under the rocks or gravel around the rim of the pond. Ensure that the pond fabric is securely held in place.
- Add moss: Collect moss from your garden or purchase it from a garden centre. You can use moss species such as willow moss, which is commonly used in ponds. Spread the moss over the pond fabric, focusing on the edges where the fabric meets the rocks or gravel. You can also tuck moss into the cracks between rocks or rub it against the fabric to encourage spore growth.
- Encourage plant growth: Moss likes a constant climate, so ensure that the pond area receives consistent moisture and shade. The moss should begin to grow and spread over the pond fabric, helping to conceal it. You can also add aquatic plants with creeping habits, such as Creeping Jenny, to further conceal the liner and create a natural look.
By following these steps, you can effectively use pond fabric and moss to conceal your pond liner, creating a natural and visually appealing pond feature in your garden.

Use a rock-textured pond liner to cover the liner
If you want to hide a hard plastic pond liner, one option is to use a rock-textured pond liner to cover it. This can be purchased from speciality shops or online. Rock-on-a-Roll is a popular brand that offers a thin, lightweight, and flexible product that can be cut and moulded to fit any three-dimensional shape. It is also cost-effective, long-lasting, and safe for fish and plants.
To install a rock-textured pond liner, start by laying it over the existing pond liner, using as many pieces as necessary to fully cover the liner and wrap it up and over the sides of the pond. Cut and bury the edges of the rock-textured liner under the soil or rocks around the rim of the pond. You can also use gravel on the bottom of the pond and pile river rocks or small boulders around the edges to create a natural, jumbled effect. Just be sure to use rounded gravel to avoid puncturing the liner.
Rock-on-a-Roll is designed to replicate the colour and texture variations of natural stone, providing an attractive and realistic look. It is made of inert materials with no chemicals that can dissolve in water, so it will not affect water quality or the health of your fish and plants. It is also resistant to UV radiation and submersion in water, ensuring long-lasting use.
Using a rock-textured pond liner is a great way to hide the liner and create a natural-looking pond without the cost and hassle of using real stones. It is important to note, however, that decorative liners should not be used to replace the actual liner, as they will not retain water in the same way.

Distract with floating and creeping plants
Floating and creeping plants can be used to distract from hard plastic pond liners. One option is to use water lettuce, a floating plant with perfectly balanced structures that permit lifelong buoyancy. It can be placed along the pond's margins to mask the liner, especially on the slopes or steep sides. Water hyacinths are another floating plant option that can be used to cover the pond liner edge.
Creeping Jenny is a popular choice for a creeping plant to disguise pond liners. It can be tucked into the rocks with its roots in the soil or water, and it will grow and cascade over the liner. It can also be trained to grow in specific directions. Creeping Jenny produces small, pretty yellow blooms. Baby gunnera is another creeping plant with emerald green, kidney-shaped leaves with delicately toothed margins. It produces panicle-shaped green flowers in the summer that develop into bright red-orange berries.
A combination of aquatic plants can also be used to disguise the pond liner. Species with floating foliage can be placed strategically to distract from the appearance of the liner, while potted plants rooted in aquatic soil can be moved further into the pond to disguise the bottom. Marginal plants, such as cattails or rushes, can be planted along the edge of the pond to soften the liner's edge and create a more natural look.
