Why is my Dwarf Sagittaria growing so tall?

Dwarf Sagittaria stretches towards the light when illumination is low. To encourage compact, carpeting growth, increase the light intensity in your aquarium.

Can I grow Dwarf Sagittaria in sand?

Yes, it can grow in sand, but because it is a heavy root feeder, you must supplement the sandy substrate with root fertiliser tabs to prevent nutrient deficiencies.

Does Dwarf Sagittaria need CO2?

No, it does not require injected CO2 to survive or grow. However, adding CO2 will drastically speed up its growth rate and help it form a carpet much quicker.

How do I trim or prune Dwarf Sagittaria?

If individual leaves are dying or excessively tall, you can trim them off near the base using aquascaping scissors. Do not cut the tops of the leaves like a lawn, as those cut leaves will eventually die off.

Why are the leaves on my new plant melting away?

Many nursery plants are grown out of water (emersed). When placed underwater, their emersed leaves die off (melt) to make way for new, submersed leaves. Simply trim the dead leaves and give it time to adapt.

About the Dwarf Sagittaria

Sagittaria subulata, commonly known as Dwarf Sagittaria, is an excellent choice for aquarists seeking a vibrant green foreground or midground plant. Native to the shallow waters of the Americas, this robust species is highly adaptable to various water parameters. Unlike more demanding carpeting plants, Dwarf Sagittaria does not require high-tech setups, making it a staple in low-tech planted tanks. Under optimal conditions, it forms a dense, grassy meadow that looks incredibly natural.
