Get Java Fern Narrow-Leaf
Propagation
Pull the plantlets that sprout along older leaves and reattach them, or split the rhizome into pieces with several leaves each.
Frequently asked questions
Does Narrow-Leaf Java Fern grow faster than the regular kind?
Not really faster, but it tends to send up more individual leaves, so a single plant fills out into a denser clump over time. It is still a slow grower overall, which is part of why it stays algae-prone on its oldest leaves.
Can I grow Narrow-Leaf Java Fern in a tall background spot?
Yes — its upright, slender leaves reach 8 to 10 inches and look great as a midground-to-background plant on taller pieces of driftwood. Attach the rhizome partway up the wood and let the leaves rise; it does not need to be near the light to do well.
