Bolbitis heudelotii

Propagating the African Water Fern is a straightforward process, though its very slow growth rate demands patience from the aquarist. The species reproduces asexually within the aquarium through rhizome division; sexual reproduction via spores is its natural method but is not a practical approach for hobbyists.

To propagate the plant, begin with a mature, healthy specimen that has a long, well-developed rhizome with abundant fronds and roots. Using sharp, sterilized scissors or a razor blade, carefully cut the rhizome into smaller sections. For the highest chance of success, each new cutting should have at least a few healthy leaves and a small bundle of roots attached. Cuttings that are too small or lack leaves may fail to establish.

Successful establishment is heavily influenced by environmental factors. New cuttings thrive in stable water conditions with good circulation, which helps prevent fungal or bacterial rot at the cut surfaces. While the plant is not demanding, providing moderate lighting can encourage the onset of new growth. As a water column feeder, access to a light regimen of liquid fertilizers can also support the development of new roots and fronds.

After separation, attach the new plantlets to a piece of driftwood or rock. Use cotton thread, fishing line, or a small amount of cyanoacrylate glue, being careful not to apply adhesive to any developing leaf buds. Crucially, ensure the rhizome is exposed to the water column and is never buried in the substrate. Be prepared for an initial dormant period where the cutting may show no visible growth as it acclimates. A key tip is to maintain clean water to prevent the cut ends of the rhizome from 'melting' or decaying. In some instances, tiny adventitious plantlets may form on older, deteriorating leaves; these can be carefully removed and grown out once they have their own small rhizome.
