Ludwigia Mullertii

Ludwigia palustris × repens

📍 Hybrid cultivar (South America origin of parent species)

Ask Finn

Ludwigia Mullertii is a hybrid stem plant known for its striking red-to-pink coloration on the undersides of leaves, especially under high light. It features narrow, lance-shaped leaves and a moderately fast growth rate, making it an excellent choice for mid-to-background placement in planted aquariums. This cultivar is more forgiving than some Ludwigia species and responds well to fertilization and CO2 supplementation.

Common Diseases

Melt on Transition

Symptoms

Leaves become translucent, mushy, and fall off when plant is first introduced or conditions change drastically

Treatment

Gradually acclimate plant to new water parameters; ensure stable lighting, temperature, and nutrient levels; trim affected leaves and maintain water quality

Iron Deficiency (Chlorosis)

Symptoms

Yellowing of new leaves while veins remain green; stunted growth; pale coloration loss

Treatment

Dose with liquid iron fertilizer (chelated iron); increase macronutrient fertilization; ensure adequate lighting to promote nutrient uptake

Algae Overgrowth on Leaves

Symptoms

Green, brown, or black algae coating leaf surfaces; reduced photosynthesis and plant vigor

Treatment

Increase water circulation; reduce lighting duration if excessive; add algae-eating fauna (Amano shrimp, Otocinclus); perform manual removal; consider algaecide if severe

Nutrient Deficiency (Macronutrients)

Symptoms

Slow growth; pale or yellowing leaves; weak stem development; poor red coloration

Treatment

Dose with comprehensive liquid fertilizer containing nitrogen, phosphorus, and potassium; consider root tabs for substrate; increase water change frequency to replenish nutrients
