A pond liner can affect the plant life in a natural swimming pond, but the impact depends on the type of liner and how it’s installed. If the liner is made from eco-friendly materials like EPDM or RPE, it generally won’t harm the plants. These materials allow for proper water circulation and can help create a stable environment for aquatic plants.
However, if the liner is not properly protected or is made from harmful materials, it could interfere with the water quality or restrict the growth of plants by affecting the nutrient balance. For example, using a liner that isn’t breathable can limit the oxygen exchange needed by certain plants. Proper installation and selecting the right liner can help ensure that plants thrive by providing a stable, healthy environment.
