Choose the Right Spot

Before you plant elodea densa in your pond, it is essential to choose the right spot. The plant needs plenty of light to grow, so make sure the place you select receives at least 6 hours of direct sunlight daily. The water should also be deep enough to allow the plant to grow to its height of around 3-4 inches.

Prepare the Pond

Once you have chosen the right spot for your elodea densa, you need to prepare the pond. Remove any weeds or debris from the water, and make sure the water is clean and clear. If the water is murky, you may need to add a water clarifier to help improve its condition.

Plant the Elodea Densa

To plant the elodea densa, follow these steps:

Remove the plant from its container or packaging, not damaging the stems or leaves.

Trim any damaged or dead leaves or stems with a pair of scissors.

Plant the elodea densa by gently pushing the stems into the substrate at the bottom of the pond. Ensure the roots are buried in the substrate but do not cover the leaves or stems with the substrate.

Plant the elodea densa in groups of 3-5 stems, about 6 inches apart. It will help the plant to grow more quickly and prevent it from becoming too dense in one area.

Care for the Elodea Densa

To ensure your elodea densa grows and thrives in your pond, providing it with the proper care is essential. These are some tips and tricks to help you care for your elodea densa:

Water Conditions: Elodea densa prefers to grow in clean, clear water with a pH between 6.5 and 7.5. It also needs plenty of nutrients, so you may need to add fertilizer to the water to help it grow.

  • Light: Elodea densa needs at least 6 hours of sunlight daily to grow. If your pond does not receive enough sunlight, you may want to add a grow light to help the plant grow.
  • Temperature: Elodea densa can grow in a wide range of temperatures, from 50°F to 80°F. However, keeping the water temperature between 65°F and 75°F for optimal growth is best.
  • Pruning: To prevent the elodea densa from growing too quickly and becoming too dense, you may need to prune it occasionally. Simply use scissors to trim the stems to your desired length.
  • Controlling Growth: Elodea densa can proliferate and become invasive if not adequately controlled. To prevent it from taking over your pond, you may need to thin out the plant occasionally. You can gently pull up some of the stems and roots.

Other Aquatic Plants to Consider

If you are looking for other aquatic plants to add to your pond, here are some options to consider:

  • Anacharis: Also known as Brazilian waterweed, anacharis is a popular plant for aquariums and ponds. It is easy to grow, provides oxygen for fish, as well as helping to control algae growth.
  • Egeria: Egeria, also known as the leafy elodea or dense waterweed, is a fast-growing aquatic plant that can help to control algae growth in ponds and aquariums. It is easy to care for and can survive in various water conditions.
  • Water Lettuce: Water lettuce is a tropical live aquatic plant that can add a unique look to your pond or aquarium. It floats on the water’s surface and can provide shade and shelter for fish.
  • Common Waterweed: Common waterweed is a hardy aquatic plant that can grow in various conditions. It is easy to care for and can help to control algae growth in ponds and aquariums.

When adding new plants to your pond or aquarium, it is essential to research their specific care needs to ensure they thrive in their new environment.

Choosing the right Elodea densa for your pond

When choosing Elodea densa for your pond, could you buy it from a reputable source? Look for healthy plants with green leaves and strong stems. Avoid buying plants with yellow leaves or signs of damage. You can also ask for advice from a local aquatic plant expert or a nursery to help choose an amazing plant for your pond.

Preparing the pond for planting

Before planting elodea densa in your pond, it is essential to prepare the pond. It involves cleaning the pond, removing debris or dead plants, and ensuring the water conditions suit plant growth. You can test the pH and nutrient levels of the water using a water testing kit and adjust the requirements as needed to ensure that they are within the optimal range for elodea densa growth. 

Planting Elodea densa in an aquarium

When planting Elodea densa in an aquarium, rinse the plants thoroughly before planting to remove dirt or debris. Cut the stems into smaller pieces, and plant them in the substrate, leaving the leaves and upper parts of the branches above the water’s surface. Make sure to provide enough light and nutrients for the plants to grow.



How fast does Elodea densa grow?

Elodea densa is a fast-growing plant that can grow up to several inches daily in the right conditions. However, its growth rate can be controlled by limiting the light and nutrients it receives.

Can Elodea densa survive in the wild?

Elodea densa is native to South America and has been introduced to different parts of the world as an aquarium or pond plant. It can also grow in the wild in certain conditions, but it is considered an invasive species in some areas where it can outcompete native plants and disrupt ecosystems. It is important to only grow elodea densa in areas where it is not considered invasive and to dispose of it properly to prevent it from spreading to other water bodies.
