Can I Grow Aquarium Plants in Pots?

Many aquarium owners enjoy growing live plants in their tank. Besides providing a natural and attractive look, living plants offer many benefits to the health of fish and other aquatic creatures. However, sometimes keeping plants rooted in the substrate can be difficult. In this case, some plant enthusiasts wonder if growing aquarium plants in pots would be a viable option.

The Pros and Cons of Growing Aquarium Plants in Pots

Growing aquarium plants in pots has both advantages and disadvantages. One benefit of using pots is the ability to move plants around the tank more easily. For example, if the plants are blocking too much light from reaching other species or if they need more water circulation, moving the pots is simple. Potted plants are also excellent for quarantine tanks, preventing invasive species from taking hold in the substrate. Additionally, pots allow for easier planting and replanting of plants which can be accomplished without disturbing the substrate too much.

On the downside, pots have the potential to distract from the natural look of the aquarium. The pots can be obtrusive or ugly, and it is necessary to find pots that complement the tank’s decor. Planting in pots also limits the choices for substrate to a growing medium like peat moss or vermiculite. Such mediums do not provide as many nutrients as an aquarium substrate or fertilizers meant specifically for plants. Also, potting plants may require additional lighting that would not be necessary in a tank with living plants rooted in the substrate.

The Types of Plants that Can Be Grown in Pots

The types of plants that can be grown in pots are not limited. Both foreground and background plants can be planted in pots, giving versatility and flexibility to the aquarium’s design. Stem and floating plants work well in pots as their roots are enclosed, and they don't require as much space to flourish. Anubias and Java Fern do particularly well in pots as they’re epiphytes, and their roots don’t require substrate.

How to Plant Aquarium Plants in Pots

The best way to plant aquarium plants in pots is to set the potting medium first before positioning the plant. A suitable medium could be gravel or peat moss, and it should fill around half of the pot. After setting the medium, the plant can be added, and the remaining medium added around the plant to hold it in place. It is recommended to use long tweezers for placing the plants to prevent damage to the leaves, particularly with delicate or small species. The pot should then be positioned in the aquarium where it gets the right amount of light and water circulation.

Caring for Aquarium Plants in Pots

Maintaining plants grown in pots is virtually the same as for plants in the substrate. They still require proper lighting, CO2, and nutrients. A regular fertilization schedule along with water changes will keep the plants healthy and flourishing. Algae growth can be a problem, particularly on the exterior of the pot, but this can be eliminated with regular cleaning. To avoid disturbing the substrate too much, it's best to remove the plant from the pot before trimming it.

Conclusion

Overall, growing aquarium plants in pots can offer some benefits to the aquarium, particularly if the substrate is not suitable for rooting plants. However, it also has disadvantages, adding another element of appearance to an already decorated aquarium. Regardless, it remains a useful way of growing plants, providing the correct substrate and lighting used, and offering a great alternative for quarantine tanks.
