Propagating Bucephalandra Kedagang: Rhizome Division Guide

Learn how to propagate the slow-growing epiphyte Bucephalandra Kedagang by dividing its creeping rhizome and attaching pieces to wood or rock.

Overview

Bucephalandra is a genus of flowering plants in the family Araceae, with all formally described species discovered in Borneo. These are rheophytic plants that naturally grow as dense mats over stones or rocks in flowing streams and rivers of moist tropical forest. The 'Kedagang' cultivar is one of the most popular varieties, prized for its narrow dark-green leaves with an iridescent blue-green shimmer and wavy edges.

Like all Bucephalandra, Kedagang has creeping, rooting stems and is known for slow growth in the aquarium. It is grown as an epiphyte, attached to hardscape rather than rooted in substrate, and can even produce small white flowers underwater.

Propagation Method (Rhizome Division)

Bucephalandra propagates from its creeping rhizome. The reliable method is rhizome division: cut the rhizome into pieces, making sure every piece keeps several healthy leaves and its own roots. Supply from farms often arrives in large mats or clumps, and separating clumps into individual plants allows much faster, healthier propagation, as each plant gains better access to water flow and light.

Step-by-Step

1. Remove the parent plant and rinse the rhizome to expose its structure.
2. Using clean scissors, cut the rhizome into segments, leaving several leaves and roots on each piece.
3. Tie each piece to wood or rock with cotton thread or fishing line, or use a dab of cyanoacrylate gel glue on the rhizome underside.
4. Position pieces where they receive gentle flow and subdued light.
5. Once new roots grip the hardscape, remove any thread that has not dissolved.

Conditions for Healthy Growth

Bucephalandra grows well under lower lighting; subdued light below roughly 50 umol PAR (low-light species do well at 15-30 umol PAR) keeps it easy to manage and helps avoid algae. It is hardy enough to survive without CO2 injection or heavy fertilisation, but reaches its full potential with good flow and supplemental CO2. Stable, cool, clean water is the most important factor.

Maintenance

Because growth is slow, little trimming is needed. Keep the rhizome free of debris, maintain steady water parameters, and only divide again once a clump has grown large. Remove any melted or decaying leaves promptly to keep flow around the rhizome clean.

Common Challenges

The second frequent mistake is burying the rhizome, which causes it to rot. Introduce Bucephalandra only after the tank has stabilised, since it requires stable conditions, and expect slow recovery and growth.
