When setting up a thriving aquascape, one question often arises: Do aquarium plant roots need to be covered? The answer depends on the type of plant and its care needs.
Many popular aquarium plants like Anubias, Java Fern, and Bucephalandra can grow well with their roots exposed, often attached to rocks or driftwood where they can absorb nutrients directly from the water.
However, certain aquarium plants, like Amazon Sword, Cryptocoryne, Dwarf Hairgrass, and Vallisneria, grow best with their roots covered in nutrient-rich substrate. This helps them absorb essential nutrients and stay firmly planted, creating a lush, natural aquascape.
In this blog post, we will explore the common question, “Do aquarium plant roots need to be covered?” and share essential tips for creating a thriving aquascape.
Do Aquarium Plant Roots Need to Be Covered?
Aquarium plants can be categorized into three groups: rooted, floating, and epiphytic. Rooted plants such as Amazon Sword and Vallisneria require the roots to be buried in the substrate. This is essential for nutrients and anchorage.
Likewise, floating plants such as Duckweed and Frogbit do not require the burial of the roots. They absorb nutrients from the water directly.
Epiphytes, such as Java Fern and Anubias, attach to rocks or driftwood and also don’t need substrate coverage. They take in nutrients through their leaves and exposed roots. The way roots interact with the substrate and water helps plants grow strong and stable.
However, you can cover their roots with substrate if you wish to enhance stability or aesthetic appeal in your aquascape.
Benefits of Covering Aquarium Plant Roots
Covering the roots of aquarium plants has many benefits. First, it helps keep the plants in place. This stops them from floating away and keeps them stable. Second, when the roots are covered, the plants can get important nutrients from the soil.
This helps them grow well and have bright leaves. Also, a covered root system helps the plant’s roots grow strong. Strong roots can take in more water and nutrients. This means healthier plants that grow better and look more colorful.
Best Practices for Root Coverage in Aquascaping
Whenever you are aquascaping and need to cover the plant roots, always ensure to use quality substrates such as soil or special aquatic plant soils that are necessary for rooted plants such as the Amazon Sword or Cryptocoryne.
Ensure that the substrate is also sufficiently deep, approximately 2-3 inches, so as to give the plants enough stability as well as facilitate the growth of their roots.
Don’t pack the substrate too tight, so water and air can reach the roots. For plants like Anubias and Java Fern, attach them to rocks or driftwood instead of burying their roots.
Check the substrate often for any signs of decay or missing nutrients to keep your aquascape healthy and thriving.

Troubleshooting Root Issues in Aquarium Plant
By examining the plants in the aquarium thoroughly and promptly, you can identify basic issues with them. Symptoms of rotten and dying roots include: roots changing color to brown or black, roots feeling soft to the touch, decreased growth rates, and yellowing leaves.
These signs may indicate root rot or a nutrient deficiency in the plants.
If you see dark or slimy roots, cut away the bad parts with clean scissors. This will help the healthy roots get better water. Yellow leaves or slow growth usually mean the plants need nutrients. You can fix this by using liquid fertilizers or root tabs.
When moving plants, handle the roots gently. Make sure the rhizomes (like in Anubias and Java Fern) stay above the substrate, so the smaller roots can find places to attach. Acting quickly and taking care of your plants can stop serious root problems and help them grow well.
Conclusion: Do Aquarium Plant Roots Need to Be Covered?
To facilitate healthy aquascaping, it is necessary to understand the root coverage requirements of aquarium plants. Most conventional plants require the presence of substrate to cover their roots.
But other plants, such as Anubias, Java Fern, and different types of mosses, do not necessarily have to have their roots covered in order to thrive. Instead of using a one-size-fits-all approach, it is important to understand the needs of each plant specifically.
Whether you choose to grow plants that require soil coverage or those designed to thrive without it, you can achieve your goals by offering the right type of plant management.
Provide adequate care by focusing on the plants’ well-being and abiding by care instructions to maintain an enchanting and harmonious underwater garden.
FAQs
Do aquarium plant roots need to be covered?
It depends on the type of aquarium plant. Rooted plants like Amazon Sword and Cryptocoryne need their roots covered in soil to stay stable and get nutrients.
Do aquarium plants need to be buried?
It depends on the type of plant: rooted plants need to be buried in substrate for nutrients and stability, while epiphytes and floating plants do not require burying.
Should you trim aquarium plant roots?
Yes, trimming aquarium plant roots encourages healthy growth and prevents overcrowding.
Do aquatic plants have root cap?
Many water-loving plants have root caps. The root cap is a protective structure at the tip of the root. It protects the soft tissues inside the root. The root cap helps the root grow into the soil. It also helps the plant sense gravity. This guides the roots to grow deeper into the ground.
Why is the root cap necessary?
The root cap is an important shield for the soft tip of a plant root as it grows and pushes into soil or other surfaces. It protects the growing cells at the root tip from damage and helps the root move through the soil.
Do aquatic plants need root tabs?
Root tabs are beneficial for rooted aquatic plants like Amazon Sword and Cryptocoryne, as they provide essential nutrients directly to the roots, but they are not necessary for epiphytes or floating plants.
