Propagating Anubias 'Minima' (A. barteri var. angustifolia): Rhizome Division

Step-by-step propagation of the narrow-leaved Anubias barteri var. angustifolia ('Minima') by rhizome division, mounting pieces on wood or rock as a slow epiphyte.

Overview

Anubias 'Minima' is the narrow-leaved variety Anubias barteri var. angustifolia, a West African aroid (family Araceae). Anubias barteri occurs in south-eastern Nigeria, Cameroon and on Bioko, growing from a creeping rhizome that stays above the substrate, tethered to litter such as rocks and wood.

It is a slow-growing, hardy epiphyte that thrives in partial or full submersion, tolerates varied lighting and needs no CO2. As with all Anubias, propagation is by rhizome division rather than topping cuttings.

Propagation Method (Rhizome Division)

Anubias barteri propagates by dividing the rhizome or by separating side shoots. A longer rhizome is cut into segments, and each segment develops into a new plant. Every division should retain enough leaves and roots to support itself while it re-establishes.

Step-by-Step

Select a mature plant whose rhizome has extended and bears several leaves.
With a clean, sharp blade, cut the rhizome into segments, each carrying 3-4 leaves and roots.
Tie or glue each segment to driftwood or rock, keeping the rhizome above the substrate and fully exposed.
Return the mount to the tank under suitable lighting and allow several weeks for new growth.

Conditions for Healthy Growth

Lighting: tolerant of varied levels; stronger light promotes faster, more compact growth, but keep it modest to avoid leaf algae.
Temperature: roughly 22-28 C (72-82 F).
CO2: not required.
Placement: epiphytic on wood or rock; the slender leaves suit the midground.

Maintenance

Keep the rhizome and roots exposed and the water clean. Growth is slow, so allow several weeks for divisions to establish. Remove aging or algae-covered leaves at the base to maintain the elegant narrow-leaf form.

Common Challenges

Algae on slow-growing leaves is the most common complaint; balance lighting and keep organic waste low. New divisions are simply slow to settle, so patience is required.
