Elodea is a popular aquatic plant that is commonly used in aquariums and outdoor ponds. It’s known for its fast growth and easy care. However, if you notice that your elodea plant is growing sideways, there could be a few different reasons for this. In this article, we’ll go over some of the common causes of sideways elodea growth and what you can do to fix it.

Lack of Light

One of the most common reasons for sideways elodea growth is a lack of light. Elodea plants require a lot of light to grow properly, especially if you want them to grow straight up. If your elodea plant isn’t getting enough light, it may start to grow sideways as it tries to reach towards the light source.

To fix this issue, you’ll need to make sure your elodea plant is getting enough light. If you’re keeping your plant in an aquarium or indoor pond, consider adding a light source specifically designed for aquatic plants. If you’re keeping your plant outdoors, make sure it’s getting at least six hours of direct sunlight each day.

Lack of Nutrients

Another reason for sideways elodea growth could be a lack of nutrients. Elodea plants require a lot of nutrients to grow properly, and if they’re not getting enough, they may start to grow sideways as they try to find more nutrients.

To fix this issue, you’ll need to make sure your elodea plant is getting enough nutrients. Consider adding a fertilizer specifically designed for aquatic plants to the water where your plant is growing. You can also add some organic matter like fish waste or decaying leaves to the water to provide more nutrients.

Water Movement

Another factor that can cause sideways elodea growth is water movement. If the water in your aquarium or pond is moving too much, it can cause your elodea plant to grow sideways as it tries to avoid the current.

To fix this issue, you’ll need to adjust the water flow in your aquarium or pond. Consider adding a filter or adjusting the flow rate of your existing filter to create a more gentle current. You can also add some plants or other decorations to your aquarium or pond to help break up the water flow.

Crowding

Finally, elodea plants can start to grow sideways if they’re overcrowded. If you have too many plants in one area, they may start to push against each other, causing some of them to grow sideways.

To fix this issue, you’ll need to thin out your elodea plant population. Remove any plants that are overcrowding the area and replant them in a different location if necessary. This will give your remaining elodea plants more space to grow straight up.

FAQ

Can I trim my elodea plant if it’s growing sideways?

Yes, you can trim your elodea plant if it’s growing sideways. This will help encourage new growth and can help your plant grow straight up again.

How often should I fertilize my elodea plant?

You should fertilize your elodea plant every two weeks during the growing season. Be careful not to over-fertilize, as this can harm your plant.

Can I use tap water for my elodea plant?

Yes, you can use tap water for your elodea plant. However, make sure to dechlorinate the water first by letting it sit for 24 hours or using a dechlorinator product.

In conclusion, sideways elodea growth can be caused by a variety of factors, including lack of light, lack of nutrients, water movement, and crowding. By identifying the cause of your plant’s sideways growth and taking the appropriate steps to fix it, you can help your elodea plant grow straight up and thrive.
