Vallisneria Overview:

Vallisneria is also commonly known as eelgrass, tape grass or vallis. It is a fresh water plant that can be kept in aquarium or pond. Vallisneria is found in abundance in Asia, Africa, Europe & North America.

Vallisneria is a tough plant recommended for beginners. People in earliest days used to keep eelgrass in aquarium & still this plant is famous & a lot of hobbyists keep them in aquarium or pond.

Vallisneria is confused sometimes with the superficially similar Sagittaria when this plant is cultivated submerged.

Vallisneria should never be confused with Zostera species, marine seagrasses that are commonly known as eelgrass.

Vallisneria likes to grow in slow moving water, & it is usually found in ponds & streams. It prefers to cultivate in shallow water, & are rarely discovered in deep waters that are more than 10 feet deep.

Origin of Vallisneria:

Eelgrass is native to Asia, Australia, North America, Central America & South America. It is usually discovered in the East of North America, but according to recent reports this plant is spreading to the west too.


Vallisneria Care & Maintenance:

Vallisneria Americana are very tough, & can live in harsh conditions. They love to grow in hard, alkaline water & may grow slowly in soft, acidic water. It can even grow in brackish water & grow in rivers & bays with different levels of salinity.

When you are deciding substrate for pond or aquarium, then my recommendation is to use CaribSea Eco-Complete. This substrate can help the growth of plants & they cultivate lush & thick.

Vallisneria Americana does not need you to add carbon dioxide to pond, as they grow in shallow water which does not have enough carbon dioxide. This plant however needs addition of iron rich fertilizer for better growth. Make sure you add fertilizer to pond on a weekly basis if you want optimum growth.

Tape grass needs high lighting but they can even do well in modern lighting. However, under moderate lighting the growth rates of this plant is slower. If you want to select a lighting for Tape grass, make sure you select a high quality LED or a plant bulb.

Do not trim leaves of the plant; & if you hurt the leaves then they will rot away & will pollute pond water. If you want to trim leaves then use sharp scissors for this job.


Propagate Vallisneria:

Eelweed regrows through runners in your home tank, which will root, & then grow into a fresh plant. Make sure you do not separate runners from the plant until the complete growth of the leaves. Then you can move it & replant elsewhere in the tank. If often takes up to 4 weeks for the fresh plant to adjust to being relocated & start growing again.

Eelweed rarely grows through seeds indoor, & it usually just grows in ponds. If you are hobbyist make sure you grow this plant through seeds in ponds. During growth, white female flowers grow to the water surface while little male flowers escape & float to the water surface. Then they are caught by female flowers & it helps in pollination of the plant. Fertilization makes a long cylindrical pod, which contains little seeds.

Tape grass is the best plant against fish that hurt or uproot them. They can make the best choice for hobbyists who want to keep cichlid but some of the species can still hurt them over time, but their endurance rate is much better than other types of pond plants.


Vallisneria Tank Condition:

Minimum Aquarium Size for Jungles vals: 29 Gallons (110 Litres)

Level of Care for Jungles vals: Beginner

Water Conditions for Jungles vals: pH of 6 to 9, & Moderately Hard to Very Hard Water

Maximum Size of Jungles vals: 6 feet


Grow Vallisneria in Pond:


It is very easy to grow Vallisneria in pond or aquarium. They prefer high lighting & but can grow in moderate lighting too.

This plant does not need more carbon dioxide because it grows in shallow water with low CO2. But you can add fertilizers to grow them well.

I took Vallisneria & put it in a netted pot. Then I filled the pot with substrate to protect Vallisneria from getting damage. Do not damage the Vallisneria & ensure it is in the center of the pot before filling it up with substrate. Also choose a large netted pot because Vallisneria cultivates fast so make sure you are pre-prepared for upcoming challenges.

Give a good rinse to the pot so that impurities on the substrate are washed out. Quickly place the pot at the bottom of the pond & ensure it is completely submerged in water. Fill the pond with de-chlorinated water. Start the pond filter & you are good to go.


Pros & Cons of Vallisneria in pond:

Eelgrass makes vast forests using its long ribbon leaves, which can as a shelter for a lot of fish & invertebrates.

Channel grass can tolerate harsh conditions & it is a beginner’s plant.

Many hobbyists love to keep channel grass in aquarium. It grows fully submerged & it needs substrate to dip its root in it. You can keep this plant in tanks or ponds with fish that love to dig substrate but due to deep roots it makes it difficult for fish to displace its roots. Due to its size, hobbyists use it as aquarium background, & the plant speedily reach the top of small aquarium & it is better recommended for tall aquariums or ponds.

Vallisneria Americana are among the few species of plants that can grow in brackish water, though it will affect their cultivation rate & propagation.

Do not trim leaves of coiled vallisneria because if you injure the leaves then they will rot away & will toxic pond water. If you wish to trim leaves of coiled vallisneria then use sharp scissors. Trimming of Vallisneria Americana is a problematic task because you can pollute pond water if you do it in wrong way.
