About Eleocharis sp. 'Mini'
Eleocharis sp. 'Mini' · also called mini hairgrass, micro hairgrass · tropical
Eleocharis sp. 'Mini' is the most compact dwarf hairgrass, forming a fine, grass-like aquarium carpet only 2-4 cm tall. Under strong light and pressurised CO2 it spreads quickly by runners, ideal for foreground lawns. It tolerates a wide range of soft to moderately hard water and trims easily to stay dense.
Preferred mix: Nutrient-rich aquatic substrate
Watch for — Carpet lifting off substrate: Insufficient root anchorage or being uprooted by fish; plant small portions deep and let runners knit in before heavy maintenance.
Why eleocharis sp. 'mini' needs this mix
Eleocharis sp. 'Mini' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Eleocharis sp. 'Mini' is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons eleocharis sp. 'mini' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates eleocharis sp. 'mini''s roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for eleocharis sp. 'mini'.
pH — does it matter for eleocharis sp. 'mini'?
Eleocharis sp. 'Mini' is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
