Microsorum pteropus "Needle Leaf"

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

Like all Java Ferns, it should be attached to driftwood or stones with thread or glue. The rhizome must remain unburied to prevent fatal rotting. It is best utilized in the midground to soften hardscape features.

Botanical form

rhizome or creeping stem

It boasts extremely thin, needle-like leaves that are much narrower than the 'Narrow' variant. The leaves are delicate in appearance but tough in texture, growing from a creeping rhizome. It forms dense, arching clusters over time.

Growth

Slow

The growth is very slow, requiring patience to achieve a full, bushy appearance. It requires very little maintenance due to this slow growth rate. Under ideal conditions with CO2, the plant's development is noticeably healthier.

Substrate

None

Column fertilization

Recommended

Liquid fertilization is the sole method of feeding this epiphytic plant. A comprehensive fertilizer dosed lightly is usually adequate. Special attention should be paid to potassium levels to avoid necrotic spots on the thin leaves.

Root fertilization

None

Root feeding is completely ineffective as the plant does not draw nutrients from the substrate. Its roots are designed purely to grasp onto rough surfaces. It is an excellent choice for setups without nutrient-rich soils.

Trimming

Occasional

Trimming consists solely of removing decaying or unsightly leaves at their base on the rhizome. Trimming the leaves themselves will halt their growth and cause them to rot. It is best left alone to form natural, dense clumps.

Propagation

Cuttings

It is easily propagated by cleanly severing the rhizome into smaller pieces. It also naturally generates small daughter plants on the edges of its mature leaves. These plantlets can be carefully removed and tied to new hardscape.

Sensitivity

Moderate

It is robust against fluctuations in water chemistry and temperature. It is susceptible to black beard algae if placed under very high light with poor flow. Consistent water parameters and moderate light keep it pristine.

Layout role

group, Epiphyte, Midground, Nano, Foreground

It provides unparalleled fine texture and an elegant, sweeping aesthetic to the midground. Its extremely thin leaves create a delicate contrast against bulky rocks and wood. It is highly prized by aquascapers for its refined appearance.
