Propagating Anubias Barteri: Rhizome Division Guide

A practical guide to propagating Anubias barteri by dividing its rhizome, mounting pieces on wood or rock, and keeping the rhizome above the substrate to avoid rot.

Overview

Anubias barteri is a robust West African epiphyte first described in 1860. The broadleaf form bears leathery leaves that can reach about 12 inches. Its rhizome remains above the substrate, tethered to rocks and wood, and the plant grows both partially and fully submerged. Hardy and low-light, it is an excellent, beginner-friendly choice.

Propagation Method: Rhizome Division

Anubias barteri is propagated through rhizome division or by separating side shoots. The thick horizontal rhizome is cut into sections, each becoming a self-sufficient plant. Growth is slow, so be patient, but the technique is straightforward and very forgiving.

Step-by-Step

Lift the mother plant and rinse the rhizome to expose its full length.
With clean scissors, divide the rhizome into pieces, keeping at least 3-4 leaves with their roots on each section.
Mount each division on driftwood or rock — tie with thread or use a small line of super-glue gel, holding for about 30 seconds until set.
Return the divisions to the tank with the rhizome fully above the substrate.
Allow roots to grow over the hardscape, gradually anchoring the plant in place.

Conditions for Healthy Growth

Lighting: low light is enough; in stronger light leaves grow more quickly and stay more compact.
Temperature: 22-28 °C (72-82 °F).
pH 6-7.5, GH 3-10.
CO2 is not required; nutrients are drawn mainly from the water column.

Maintenance

Feed an all-in-one liquid fertilizer as needed, because rhizome plants absorb nutrients primarily from the water. The rhizome creeps horizontally while leaves rise vertically; with such slow growth, routine trimming is minimal. Remove any leaf that becomes heavily covered in algae.
