Hedyotis Salzmannii care guide

Hedyotis Salzmannii (Hedyotis salzmannii) — medium light, 20-28 °C, pH 5.5-7, CO2 recommended.

Overview

Hedyotis Salzmannii (Hedyotis salzmannii) is a fine-leaved plant of the family Rubiaceae, grown as an aquarium plant. A delicate creeping stem plant with fine, paired leaves. Forms a low-growing mat when given sufficient light, making it suitable for foreground use or as a carpet alternative. Moderate growth rate allows it to fill in gradually without becoming invasive.

Placement

In aquascapes this plant suits the foreground.

Propagation

Propagation is by stem cuttings replanted into the substrate, and runners that throw daughter plants on the substrate; daughter plants are separated once they have formed several leaves and visible roots.

Common issues

Pale or stunted new growth usually signals a nutrient or iron deficiency, while algae on older leaves often follows light that exceeds the available nutrients or CO2; correcting fertilisation and trimming affected parts resolves most cases.
