Plant Profile

• Scientific Name: Rotala spp. (commonly R. rotundifolia, R. wallichii)
• Common Names: Rotala, Dwarf Rotala, Indian Toothcup
• Origin: Native to Southeast Asia, where it thrives in tropical wetlands and shallow water.

Appearance

Rotala exhibits slender stems with small, delicate leaves that can range in colour from green to striking shades of red, pink, and orange. Depending on the species, the leaves may be round or needle-like. With proper care, Rotala can grow 20–50 cm tall, making it ideal for midground or background planting.

Care Requirements

Lighting

Rotala thrives in moderate to high light. For vibrant red hues, provide intense lighting using LEDs or T5 fixtures. Lower light may result in slower growth and greener leaves.

Water Parameters

• pH: 6.0–7.5 (slightly acidic to neutral)
• Temperature: 22–28°C
• Hardness: Soft to moderately hard water (2–10 dGH).

Nutrient Requirements

Rotala benefits from regular nutrient supplementation. Iron-rich fertilizers enhance its red colour, while root tabs or liquid fertilizers ensure robust growth.

CO2

While Rotala can grow without CO2, injecting CO2 significantly enhances growth rate and intensifies colouration, especially for red varieties.

Water Flow

Rotala prefers moderate water flow, which helps distribute nutrients and CO2 evenly. Excessive flow may cause damage to its delicate stems.

Propagation

Rotala is one of the easiest plants to propagate:

1. Cut a healthy stem just below a node.
2. Remove the lower leaves to expose the stem.
3. Plant the cuttings into the substrate, ensuring they are upright and stable.

Within weeks, the cuttings will root and grow into lush clusters.

Companion Plants

Rotala pairs beautifully with carpet plants like Hemianthus callitrichoides (Dwarf Baby Tears) and taller species like Vallisneria.

Troubleshooting

Common Issues:

• Melting leaves: Caused by sudden changes in water conditions; transition plants slowly.
• Algae growth: Reduce light intensity and adjust nutrient dosing.
• Slow growth: Increase CO2 and fertilization.
• Leggy stems: Trim regularly and increase light intensity for compact growth.

Additional Tips

• Pruning: Trim the tops frequently to encourage bushier growth.
