Rotala Macrandra Red

The Giant Red Rotala is highly demanding, needing high-intensity lighting, no shade, and high Co2 injection. To prevent shading, the individual stems must be planted far enough apart for the lower leaves to get enough light. The plant grows quickly up to 4” per week, in ideal conditions. To keep the distinctive red color, ensure that the Rotala has plenty of phosphates (1.5 – 2.0 ppm) and not too much nitrate. (10ppm or less.) An incorrect amount of either of these nutrients will lead to stunted growth or discolored leaves.
