Curly Pondweed (Potamogeton crispus)

A hardy native oxygenating pond plant with crinkled underwater leaves for wildlife ponds and deeper water

Curly Pondweed (Potamogeton crispus) is a hardy native oxygenating pond plant with distinctive wavy, crinkled underwater leaves. It is especially useful for adding natural submerged cover to wildlife ponds, fish ponds and larger garden ponds.

The plant grows below the surface and creates valuable habitat for tadpoles, newts, aquatic insects and small fish. Its textured foliage gives a more natural appearance than many plain stem oxygenators and can help create shelter in deeper pond areas.

During active growth, Curly Pondweed produces oxygen during daylight and uses nutrients from the water. It is best used as part of a varied planting scheme with other oxygenators, waterlilies and marginal pond plants.

Curly Pondweed can grow well in cooler water and often performs strongly early in the season. It may naturally change in appearance through the year as growth responds to temperature, light and pond conditions.

The weighted bunches can be placed directly into the pond, tucked into fine substrate or planted into an aquatic basket for more controlled positioning.

Potted Oxygenators and Bunched Oxygenators

Potted oxygenators are supplied rooted in aquatic soil and are usually placed on pond shelves or in shallow water. They often provide useful cover near the water surface, making them valuable for amphibians, froglets and aquatic insects.

Bunched oxygenators are usually weighted and placed into deeper areas of the pond, where they can sink towards the pond floor and root into the substrate.

Curly Pondweed is best used as a submerged weighted bunched oxygenator for deeper pond areas. It pairs well with potted oxygenators on shallow shelves and marginal plants around the pond edge.

Care Instructions

• Place the weighted bunches directly into the pond and allow them to sink into position. For best establishment, tuck the weighted ends into gravel, fine substrate or natural pond silt.
• Start in clearer water where light can reach the foliage. Growth may be reduced in very shaded or very murky ponds.
• Thin excess growth if required. Leave removed material beside the pond for 24 hours before composting so small pond creatures can return to the water.
• The plant may vary in appearance through the season, which is normal for submerged pond plants.

Flowering Period

Curly Pondweed can produce small, inconspicuous greenish flower spikes, but it is grown mainly for its submerged crinkled foliage and oxygenating value.
