Rotala Singapore

Rotala sp.

PlantaeTracheophytaMagnoliopsidaLythraceae

Variety of Rotala · Singapore

📍 Singapore / Southeast Asia

Ask Finn

A compact Rotala with narrow, lance-shaped leaves that turn a warm orange-red under good light and CO₂. Slower and more compact than R. rotundifolia, making it easier to maintain as a neat midground or background plant without constant trimming. The red-orange colouration develops even at moderate light levels with CO₂, making it more accessible than demanding species like R. macrandra. A versatile choice for adding red tones to mid-sized scapes.

Common Diseases

Nutrient Deficiency (Iron/Macronutrients)

Symptoms

Yellowing or pale leaves, stunted growth, loss of red coloration despite adequate light

Treatment

Increase fertilizer dosing with emphasis on iron supplements; ensure CO₂ is present; test and adjust macronutrient levels (nitrogen, phosphorus, potassium)

Algae Overgrowth on Leaves

Symptoms

Green or brown algae coating leaf surfaces, reduced photosynthesis, plant appears dull

Treatment

Reduce light duration to 8-10 hours daily; increase water changes; add algae-eating shrimp or fish; improve water circulation; ensure CO₂ levels are adequate

Melting (Tissue Decay)

Symptoms

Leaves become translucent, mushy, and dissolve; stems soften and deteriorate

Treatment

Improve water quality with frequent partial water changes; ensure stable temperature (20-28°C); increase CO₂ and light gradually; remove severely affected portions

Slow Growth or Stagnation

Symptoms

Minimal new leaf development, plant appears static, leaves remain small

Treatment

Verify CO₂ injection is functioning; increase light intensity to medium-high; boost fertilizer regimen; ensure substrate is nutrient-rich; check water parameters for imbalances
