About Goldtau Tufted Hair Grass
Deschampsia cespitosa 'Goldtau' · also called gold dew tufted hair grass, goldtau hair grass · flowering
'Goldtau' (Gold Dew) is a compact, refined selection of tufted hair grass forming neat mounds of dark green foliage topped by a haze of fine flowers that open reddish-bronze and age to glowing golden-yellow. More restrained and less aggressively self-seeding than the species, it suits smaller gardens and shade borders, holding its airy seedheads attractively into autumn and winter.
Preferred mix: Fertile, moisture-retentive loam
Watch for — Drought stress: Browns and crisps in dry soil; maintain even moisture and cut back scorched foliage to restore appearance.
Why goldtau tufted hair grass needs this mix
Goldtau Tufted Hair Grass hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Goldtau Tufted Hair Grass comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons goldtau tufted hair grass struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for goldtau tufted hair grass — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets goldtau tufted hair grass dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for goldtau tufted hair grass?
Goldtau Tufted Hair Grass prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for goldtau tufted hair grass straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh goldtau tufted hair grass's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for goldtau tufted hair grass covers the timing and technique step by step.
