Salvinia natans, commonly known as Floating Watermoss or Floating Fern, is a small floating aquatic plant that is native to Europe and Asia. It is appreciated for its delicate and textured foliage, as well as its ability to provide shade and cover in ponds and water gardens. Here's a detailed description and care guide for Salvinia natans:

Salvinia natans is a free-floating aquatic plant that forms dense mats on the water's surface. It features small, oval-shaped leaves that are covered in fine hairs, giving them a velvety appearance. The leaves are arranged in pairs, with one leaf acting as a floating structure and the other submerged beneath the water. This unique arrangement allows the plant to float on the water's surface. The leaves have a green upper surface and a lower surface covered in fine root-like structures that aid in buoyancy and nutrient absorption. The plant reproduces through budding, with new plants developing from the edges of the leaves.

Care Guide:

Lighting: Salvinia natans thrives in bright, indirect light. It prefers partial shade or filtered sunlight. While it can tolerate some direct sunlight, it is best to provide some shade during the hottest parts of the day to prevent excessive drying of the plant's foliage.

Water: Floating Watermoss is an aquatic plant and requires water to survive. It can grow in both still and slow-moving freshwater environments, such as ponds, lakes, and water gardens. The water temperature should be within a range of 60-82°F (15-28°C) for optimal growth. Avoid placing the plant in water with strong currents or extreme temperature fluctuations.

Nutrient Requirements: Salvinia natans obtains nutrients directly from the water. However, providing a balanced aquatic plant fertilizer or liquid fertilizer specifically formulated for water plants can promote healthy growth. Follow the instructions on the packaging for the appropriate dosage and frequency. Regular water changes also help maintain good water quality and nutrient levels.

Water Quality: Maintain good water quality for the health of Salvinia natans and other aquatic organisms. Regularly test the water pH, which should be slightly acidic to neutral (around 6.5-7.5). Avoid excessive levels of ammonia, nitrates, and phosphates, which can negatively impact the plant. Perform regular water changes to maintain optimal water conditions.

Algae Control: Salvinia natans can help control algae growth by shading the water surface and limiting sunlight penetration. However, excessive algae growth can still occur. Regular maintenance, such as removing excess debris and manually removing algae, can help keep the plant healthy and prevent overgrowth.

Winter Care: Salvinia natans is not frost-tolerant and will not survive freezing temperatures. In colder regions, it is best to move the plant indoors or into a heated greenhouse during winter. Alternatively, you can create a frost-free area in your pond using a heater or by moving the Floating Watermoss to a deeper part of the water, where it is less likely to freeze.

Propagation: Salvinia natans naturally propagates through budding. New plants develop from the edges of the existing leaves. To propagate the plant, you can gently separate the newly formed plants and place them in a suitable location in the water. Ensure that each new plant has sufficient space to grow and receive light.

By following these care guidelines, you can enjoy the beauty and benefits of Salvinia natans in your pond or water garden. Adjust the care routine based on your specific growing conditions and monitor the plant for any signs of pests, diseases, or nutrient deficiencies. Regular maintenance and monitoring will help keep the plant healthy and thriving.

Here are some general tips and care guidelines for floating pond plants:


Choose floating plants that are suitable for your pond size, water conditions, and climate. Common floating pond plants include Water Lettuce (Pistia stratiotes), Water Hyacinth (Eichhornia crassipes), and Duckweed (Lemna spp.).


Float the plants directly on the water surface or place them in containers that can float in the pond. Ensure that the plants have enough space to spread and grow without overcrowding.

Nutrient Levels:

Floating plants help maintain water quality by absorbing excess nutrients, such as nitrogen and phosphorus, which can help prevent algae growth. Monitor the nutrient levels in your pond and adjust the number of floating plants accordingly.


Most floating plants prefer full sun exposure for optimal growth. Place the plants in an area of the pond that receives at least 6-8 hours of direct sunlight per day.

Water Temperature:

Floating plants are generally tolerant of a wide range of water temperatures. However, extreme temperature fluctuations or very cold winters may affect their survival. In colder regions, consider moving the plants indoors or protecting them from freezing temperatures.

Water Circulation:

Ensure that your pond has adequate water circulation to prevent stagnant conditions and promote oxygen exchange. This can be achieved through the use of pumps, fountains, or aerators.


Regularly remove any dead or decaying plant material from the pond to maintain water quality and prevent clogging. Thin out the floating plants as needed to prevent overcrowding and maintain a balanced ecosystem.

Winter Care:

In regions with cold winters, floating plants may not survive freezing temperatures. Consider removing them from the pond before winter and overwintering them indoors in a suitable container with water and adequate light. Alternatively, treat floating plants as annuals and replace them in spring.

Legal Considerations:

Some floating plants, such as Water Hyacinth and Duckweed, are considered invasive in certain areas. Check local regulations and restrictions before introducing floating plants to your pond. Always research the specific care requirements of the floating plants you have chosen, as each species may have unique needs. By following these general guidelines and providing appropriate sunlight, water quality, and maintenance, you can enjoy the beauty and benefits of floating plants in your pond.
