Dwarf Hair Grass
Plant Profile
Dwarf Hairgrass is a long‑standing staple in the aquascaping world, thanks to its reliability and versatility in shaping a natural, field-like foreground. With its fine, needle‑thin foliage and tidy growth pattern, it forms a cohesive carpet that spreads by sending out a steady network of runners beneath the substrate, making it great for filling tight gaps around hardscape or creating scattered clusters where shrimp and nano fish love to forage. Highly adaptable, it thrives fully submerged but also performs beautifully in emersed setups like dry starts or Wabi‑Kusa, giving you plenty of flexibility in how you use it.

Key Features & Benefits
- Recreate a classic, realistic grass lawn aesthetic using its fine, needle-thin blades.
- Versatile species that adapts beautifully to both submerged aquariums and emersed setups.
Care & Planting Instructions
- Separate larger mats into small, bite-sized portions and plant them roughly an inch apart, burying them about halfway into your substrate.
- Maintain low to high lighting parameters, though higher light will drastically encourage a shorter, thicker carpet.
- Choose to inject pressurized CO2 to accelerate its growth speed and achieve a dense, wall-to-wall foreground.
- Propagate the plant effortlessly by cutting mature new growth along with the roots and moving them to bare spots.
- Master the basics by learning how to properly grow aquarium carpet plants to ensure your new layout fills in quickly, evenly, and stays free of algae.

Frequently Asked Questions
1. How do I plant potted Dwarf Hairgrass?
Use fine-tip pinsettes to push each plug deep into nutrient-rich aquasoil. Spacing plugs 1 inch apart allows the underground runners room to link together into a lawn.
2. Can Dwarf Hairgrass form a carpet without CO2 injection?
Yes. Standard Eleocharis Parvula is one of the most resilient carpeting plants in the hobby and will spread in low-tech tanks without pressurized CO2. However, providing CO2 injection and medium-to-high lighting will force the runners to fill in bare spots much faster and produce denser blades.
3. How often should I trim Dwarf Hairgrass?
Mowing Dwarf Hairgrass with sharp curved scissors every few weeks encourages the plant to stop growing upward and focus its energy on sending out lateral underground runners, helping you maintain an ultra-short, manicured carpet.
