Care, breeding and tankmates

Plant profile

Placement

Midground

This plant is best placed in the midground or background of the aquarium, depending on the tank size. Its striking red coloration makes it an excellent focal point when planted in dense bushes. It contrasts beautifully with bright green foreground or background plants.

Botanical form

Stem

It features opposite, ovate leaves that develop a deep red to magenta coloration under strong light. The stems are somewhat delicate but grow upright toward the light source. Without sufficient light, the lower leaves may turn green or drop off.

Growth

Fast

It exhibits a relatively fast growth rate under optimal conditions with high light and CO2. In low-tech setups, the growth will be moderate but manageable. Regular pruning is necessary to maintain its shape and prevent it from shading neighboring plants.

Substrate

High

Ludwigia palustris "Super Red" thrives best in a nutrient-rich aquarium soil that provides ample iron and essential minerals. Its fine root system anchors firmly into fine to medium-grained substrates, drawing up nutrients to support its intense red coloration. A substrate depth of at least 2 inches (5 cm) is recommended to accommodate its extensive root growth and prevent uprooting.

Column fertilization

Recommended

Liquid fertilizers containing a comprehensive mix of micro and macronutrients are highly recommended. Iron and nitrate levels should be monitored to ensure the red coloration remains vibrant. Regular dosing prevents nutrient deficiencies that could lead to stunted growth.

Root fertilization

None

While it absorbs significant nutrients from the water column, a nutrient-rich substrate or the use of root tabs can enhance its overall vitality. A fertile substrate helps develop a strong root system, providing stability for the fast-growing stems. This is especially beneficial in newly established aquariums.

Trimming

Regular

Frequent trimming is required to keep the plant bushy and compact. Cutting the top portion encourages the stem to produce multiple side shoots, creating a denser appearance. The trimmed tops can be replanted to propagate new individuals.

Propagation

Cuttings

Propagation is straightforward and is achieved by taking stem cuttings. Simply snip the healthy top portions and plant them directly into the substrate. They will quickly develop roots and establish themselves as new plants.

Sensitivity

Moderate

It is generally a hardy plant but can be sensitive to sudden fluctuations in water parameters. Inadequate lighting will cause the plant to lose its signature red color and revert to a dull green. It may also suffer from algae growth on the leaves if nutrients and light are not properly balanced.

Layout role

Midground, accent, Background, Nano

It serves as a brilliant color contrast in planted aquariums, breaking up the monotony of green foliage. It is often used to create striking red accents or dense colorful thickets in Dutch-style layouts. Its vibrant appearance draws the eye, making it an ideal focal point.
