Sagittaria subulata "Pusilla"

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

Best utilized as a foreground plant, planted in a grid pattern to encourage an even carpet. Ensure it receives unobstructed light to prevent it from growing too tall. It is excellent for filling in the spaces between stones in Iwagumi layouts.

Botanical form

Rosette

Characterized by its small, dwarf size, featuring short, vibrant green leaves in a rosette formation. It is generally the shortest variant of the S. subulata group. The leaves are slightly broader than the 'Needle' variety but much shorter than standard S. subulata.

Growth

Medium

Demonstrates a moderate to fast growth rate, quickly sending out runners to cover the substrate. Once established, it can form a dense mat relatively rapidly. The growth rate is highly dependent on light intensity and substrate quality.

Substrate

High

Column fertilization

Recommended

Can tolerate low water column nutrients if the substrate is rich. Light dosing of a complete fertilizer supports overall vitality. Be cautious of over-dosing water column nutrients in low-tech setups, as it can lead to algae on the slow-growing leaves.

Root fertilization

None

Essential for optimal growth and carpeting. Use a high-quality aquasoil or regularly insert root tabs near the plant bases. A strong root system is the key to healthy, continuous runner production.

Trimming

Occasional

Maintenance involves periodic thinning to prevent the carpet from becoming too thick and suffocating itself. Cut runners to stop the plant from invading other areas. Remove individual old or algae-covered leaves by plucking them from the base.

Propagation

Runners

Propagates aggressively through runners, forming a connected network of plantlets. It is very easy to divide; simply snip a runner and transplant the new rosette. This makes it an economical choice for covering large foreground areas.

Sensitivity

Moderate

Very robust and forgiving of minor fluctuations in water chemistry. It can adapt to both soft and hard water environments. Iron deficiency may cause the new leaves to appear pale or translucent.

Layout role

group, Foreground, Midground, Nano

The perfect choice for a low-maintenance foreground carpet. It creates a lush, green lawn effect that enhances the sense of scale in the aquarium. Its small size makes it ideal for nano tanks and detailed aquascapes.
