Propagating Anubias Nana 'Bonsai': Rhizome Division Guide
How to propagate the dwarf Anubias barteri var. nana 'Bonsai' by rhizome division, attach it to small stones and grow it in nano and foreground layouts.
Overview
Anubias barteri var. nana 'Bonsai' is an ultra-compact selection of dwarf Anubias with very small leaves, ideal for nano tanks and foreground epiphyte work. Like the parent species, its rhizome stays above the substrate, tethered to rocks and wood, and the leaves survive for several years.
It is extremely undemanding and grown as an epiphyte, so it is increased from the rhizome rather than planted in the substrate. Its small size makes it well suited to tying onto small stones.
Propagation Method (Rhizome Division)
Anubias is propagated by dividing the rhizome or by separating side shoots. Even on a compact 'Bonsai', the horizontal rhizome lengthens over time, and any cut section that keeps enough leaves and roots becomes an independent plant. Division is the reliable method; leaf or stem cuttings do not propagate Anubias.
Step-by-Step
- Detach the parent plant and rinse it so the rhizome is fully visible.
- Pick a cut point that leaves 3-4 leaves with roots on each side.
- Cut cleanly with sharp, sterilised scissors.
- Tie each division to a small stone or piece of wood with fishing line, or glue the roots with cyanoacrylate gel.
- Return it to gentle flow under stable light and wait for new growth before moving it.
Conditions for Healthy Growth
Anubias barteri prefers 22-28 °C, grows well submersed and needs no CO2. In stronger light the leaves grow more quickly and stay more compact, which suits 'Bonsai' since tight, small leaves are exactly the look this cultivar is grown for; it also thrives in low light.
- Temperature: 22-28 °C.
- Light: low to moderate.
- CO2: not required.
- Mount on small stones for nano and foreground placements.
Maintenance
'Bonsai' is essentially hands-off once attached. Remove the fishing line after the roots grip the hardscape themselves. Growth is slow and the leaves are long-lived, so slow algae can settle on older leaves; steady light and clean water matter more than feeding.
Common Challenges
The usual mistakes are burying the rhizome, which causes rot, and expecting quick results. After division the plant can take several weeks to settle and start new leaves. With small divisions, handle gently, keep the rhizome exposed and be patient.
