Ammannia sp. 'Bonsai'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Perfect for the foreground or midground. Its small, tree-like appearance makes it ideal for creating miniature landscapes or dense, neat bushes in nano aquariums.

Botanical form

Stem

Features thick, upright stems with small, rounded, fleshy leaves. The tips can turn slightly reddish or yellowish under intense light, while the rest remains bright green.

Growth

Medium

A very slow grower compared to other stem plants. This characteristic is highly desirable for aquascapers looking to maintain a precise layout without constant trimming.

Substrate

Medium

Ammannia sp. 'Bonsai' is a compact, slow-growing plant that benefits greatly from a nutrient-rich aquasoil to support its delicate form. Its small but active root system anchors the thick, fleshy stems while absorbing essential minerals directly from the soil. A substrate depth of 3 to 5 centimeters is sufficient to secure the plant and accommodate its moderate root development. Utilizing a fine-grained substrate helps the fine roots establish more quickly and prevents the small plantlets from floating away.

Column fertilization

Recommended

Benefits from regular liquid fertilization. Because it grows slowly, ensure that nutrients do not build up to excess levels, which could favor algae.

Root fertilization

None

Grows best in a nutrient-rich aquasoil. A good substrate provides the stability and nutrition needed for its thick stems to develop properly.

Trimming

Occasional

Trim by carefully cutting the stems at the desired height. Replant the tops if desired. The base will branch out, forming a thicker, more bush-like structure over time.

Propagation

Cuttings

Propagated via stem cuttings. Simply cut a healthy top and push it into the substrate. It roots relatively easily but takes time to start growing upwards.

Sensitivity

Moderate

Generally robust, but its slow growth makes it susceptible to green spot algae or hair algae on its older leaves if lighting is too high without adequate CO2.

Layout role

Foreground, Midground, group

Often used to create an 'avenue' or 'forest' effect in miniature. Its strict vertical growth and rounded leaves provide a neat, organized look to the aquascape.
