Hair Grass (Eleocharis parvula)

Overview

Hair Grass (Eleocharis parvula), commonly called Dwarf Hairgrass, is a popular carpeting plant characterized by fine, hair-like leaves that form a lush green lawn across the substrate. Growing to just 3–10 cm tall, this easy-care plant spreads via runners making it ideal for foreground use in both nano and standard aquariaum.

Key Features

• Compact carpet growth: Stays under 10 cm and quickly forms dense carpets through horizontal runners .
• Easy care: Thrives under medium to high lighting; CO₂ boosts speed but is not essential .
• Hardy conditions: Prefers 21–28 °C, pH 6.5–7.5, moderate GH/KH; tolerant of varied substrates though nutrient-rich base helps .
• Fast spread: Sends runners that establish new shoots, filling gaps and creating an even lawn effect .
• Trimming encouraged: Regular snipping promotes lateral growth and prevents overgrowth .

Planting & Care Guide

1. Separate small clumps (5–10 stalks) and plant 1–2 cm apart using tweezers .
2. Ensure substrate contact with roots; use nutrient-rich soil or root tabs if needed .
3. Provide 6–10 hrs of quality light daily; aim for ≥ 2 W/L to maintain strength and color .
4. Trim every 2–3 weeks to encourage lateral spread and prevent stem elongation .
5. Perform weekly water changes and maintain stable CO₂/fertilizer regime for optimal carpeting .
