Dwarf Sagittaria

Yes, it is one of the easiest carpeting plants. Dwarf Sagittaria is hardy, undemanding, and does not need CO2, so it works well in low-tech and beginner tanks. Give it decent light and a nutrient-rich substrate and it will spread on its own.

No. Dwarf Sagittaria grows well without CO2, which is why it is a favorite for low-tech and beginner tanks. Adding CO2 and stronger light will make it grow faster and stay shorter, but it is not required for a healthy, spreading carpet.

Separate the plant into individual crowns and push each one into the substrate so the white base is buried but the green leaf bases stay above the soil. Space the crowns a couple of inches apart and they will send out runners to fill the gaps. It spreads best in a nutrient-rich substrate.

It is flexible. Dwarf Sagittaria grows in low to high light. Under strong light it stays short and carpets tightly across the foreground, while in lower light it grows a bit taller and works as a grassy midground. Either way it stays green and keeps spreading.

It works best as a foreground or midground plant. In the foreground its runners spread into a grassy carpet, and in larger tanks it makes a taller grassy midground. Give it open space to spread, and thin out runners now and then so it does not creep into other plantings.
