A Myriophyllum mattogrossense either thrives or melts within the first month, and the difference is almost always down to three things you can control. The Myriophyllum matogrossense Myriophyllum mattogrossense is a workhorse plant for a reason: it tolerates a wide range of conditions and still looks good doing it.

Planting
Plant Myriophyllum mattogrossense with the crown or rhizome clear of the substrate — burying it rots the base. In a 29-gallon tank, position it mid-ground or background depending on its height. Weaker setups do fine; pair it with our Ich (White Spot) Guide guide for a layered look.
Light and CO₂
Run 10 hours of light a day on a timer to avoid algae swings. Myriophyllum mattogrossense grows under high light and beneficial, though a small, steady dose of liquid fertiliser every 2 weeks pushes denser growth.
Propagation
Stem cuttings root in substrate.
Common issues
Yellowing lower leaves usually mean a nutrient gap, not too little light. Trim dying leaves at the base, keep nitrates around 10 to 20 ppm, and avoid moving the plant every week — the Ambulia Guide walkthrough explains why stability beats tinkering.
Feeding the roots
The Myriophyllum mattogrossense takes food from water and substrate alike, so pair a root tab with a weekly liquid feed for steady green growth. Yellowing lower leaves almost always point to nutrition, not light.
