Micranthemum umbrosum

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

It is typically placed in the midground or background depending on the tank size. It should be planted in groups of several stems to form dense bushes. It requires unobstructed light to prevent the lower leaves from rotting.

Botanical form

Stem

It features delicate, round, light-green leaves arranged along fragile vertical stems. It naturally forms dense, bushy clusters as it grows towards the light. The stems are easily broken, so gentle handling is required.

Growth

Fast

This plant grows extremely fast when provided with high light and abundant nutrients. Its rapid vertical growth requires frequent maintenance to keep it in shape. In low light, it will deteriorate rapidly and lose its lower foliage.

Substrate

Medium

Column fertilization

Recommended

Heavy liquid fertilization is necessary to keep up with its fast growth. Dosing a complete liquid fertilizer ensures the stems remain robust and colorful. It draws the majority of its required nutrients from the water column.

Root fertilization

None

A nutrient-rich substrate helps establish the plant initially, although it relies more on column feeding. Root tabs can provide a helpful boost in older setups. It roots easily in most standard aquatic soils or fine gravels.

Trimming

Occasional

Frequent and aggressive trimming is required to maintain its bushy shape. Trimming encourages the plant to branch out, creating a denser cluster. Replant the healthy tops to replace older, deteriorating lower stems.

Propagation

Cuttings

Propagation is very simple by taking top cuttings and replanting them. The cuttings will quickly develop new roots and continue growing. Leaving the trimmed bottoms in the substrate will often result in new side shoots.

Sensitivity

Moderate

It is highly sensitive to low light conditions and shading from other plants. Poor water circulation can lead to debris buildup and subsequent rot in the dense bushes. It may melt significantly if water parameters fluctuate rapidly.

Layout role

group, Foreground, Midground, Nano

It is used to create bright, voluminous bushes in the midground or background. Its rounded leaves offer a contrasting texture to grass-like or needle-leaf plants. It is excellent for adding a vivid splash of light green to the aquascape.
