Overview
Dwarf Hairgrass is a classic carpeting plant that creates the appearance of a manicured lawn across the aquarium floor. It spreads via runners and forms a dense bright green mat that fish and shrimp enjoy exploring.
Care Guide
Plant small tufts in a grid pattern across the foreground to encourage even spreading. Provide CO2 injection and strong lighting for the best carpet density, and trim the blades to about one inch to promote horizontal runner growth. Root tabs help establish the plant quickly.

Frequently Asked Questions
How long does Dwarf Hairgrass take to carpet?
With CO2 and good lighting, a full carpet can develop in two to three months. Without CO2, it grows much slower and may never form a dense carpet.
