Aquatic fern

Native to Southeast Asia, aquatic fern (Bolbitis heteroclita) is most noteworthy for its ability to grow in the water, rendering it a popular choice for aquarium tanks. The plant can grow either fully or partially submerged, as long as the conditions are right. Aquatic fern leaves resemble those of several species of poison ivy, but it lacks the latter's poisonous nature.

Distribution of Aquatic fern

Distribution Map

Aquatic fern is native to several regions in Asia, where it flourishes in a variety of humid forest conditions, predominantly in tropical climates. The plant has been introduced and now also thrives in additional locations with similar environmental settings. Moreover, aquatic fern's resilience and adaptability have allowed it to be cultivated outside its natural range, which has contributed to its spread to more diverse habitats.

Soil Type

Water: Adapted to tropical rainforests, aquatic fern thrives in high humidity and consistent moisture. It prefers evenly moist soil and exhibits moderate drought tolerance. Watering twice a week mimics its natural habitat, while stable temperatures and indirect light, typically indoors, support its vibrant growth.

Fertilize: Fertilizing aquatic fern with high nitrogen fertilizers monthly during spring and summer promotes health, but reduce in fall and winter. Use diluted liquid forms to avoid root burn, as over-fertilization can harm aquatic fern. A balanced nutrient approach supports vitality in its aquatic environment.

Pruning: Aquatic fern thrives with proper pruning, ideally in early spring. Remove dead fronds to enhance growth and water circulation. Thinning prevents overcrowding, promoting vitality. Regular pruning revitalizes aquatic fern and boosts its ornamental appeal, ensuring a vibrant presence in aquatic gardens.

Propagation: Aquatic fern can be propagated by dividing its rhizomes, ensuring each piece has a frond and roots. Secure sections to driftwood or stones using fishing line. Stable water quality and moderate lighting are essential for growth and health during the propagation process.

Repotting: Repot aquatic fern every 2-3 years to prevent overcrowding and enhance leaf growth. Use a wide, shallow container during spring, before peak growth. After repotting, keep aquatic fern submerged with stable water conditions to promote healthy development in your aquatic garden.
