Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Due to its high light requirements, it must be placed in a prominent, unshaded midground or background position. It should be planted in small, carefully manicured groups to avoid shading its own lower stems. Adequate spacing between stems ensures good light penetration and water flow.

Botanical form

Stem

It features uniquely patterned, oval to slightly elongated leaves with a distinct reticulated venation that stands out against a deep red or purplish background. The stems are somewhat delicate compared to other Ludwigia species. Its highly ornamental appearance makes it a prized collector's plant.

Growth

Medium

This plant has a moderate growth rate, even under highly optimized conditions. It takes time to acclimate to new environments and parameters. Its relatively slow growth makes it easier to maintain once established but requires patience initially.

Substrate

High

Ludwigia sp. "Guinea" benefits greatly from an iron-rich aqua soil to foster a deep root network and encourage optimal leaf coloration. It needs a substrate depth of around 2-3 inches to securely anchor its sturdy stems and prevent them from uprooting. The plant aggressively pulls nutrients through its roots, so a nutrient-depleted substrate can quickly lead to stunted growth and faded colors.

Column fertilization

Recommended

Heavy water column fertilization is mandatory, requiring daily dosing of a comprehensive fertilizer. It is particularly sensitive to micro-nutrient deficiencies, which manifest as pale or deformed new leaves. Keeping nitrates and phosphates readily available is crucial for its survival.

Root fertilization

Recommended

A rich, active substrate is essential for this demanding species. It benefits greatly from the addition of high-quality root tabs. A strong root system helps it endure the stress of trimming and environmental fluctuations.

Trimming

Occasional

Trimming should be done with care, as the plant can be slow to recover if cut too aggressively. Top the stems and replant them, leaving a healthy portion of the base to regenerate. Avoid letting the plant become too dense, which can lead to poor circulation and lower leaf loss.

Propagation

Cuttings

Propagation is achieved through stem cuttings. Carefully cut healthy tops and plant them in a nutrient-rich substrate. Ensure cuttings receive ample light and CO2 to encourage quick rooting and prevent rot.

Sensitivity

Moderate

Ludwigia sp. 'Guinea' is extremely sensitive to fluctuations in CO2, light, and nutrients. It is highly susceptible to algae growth if parameters are unbalanced. It requires pristine water conditions and is recommended only for experienced aquascapers.

Layout role

Midground

It is best used as a striking focal point or rare accent plant in high-tech aquascapes. Its stunning pattern and coloration make it a standout against finely textured green plants. It is highly valued in Dutch-style tanks for its unique visual characteristics.
