About Gold Dew Tufted Hair Grass
Deschampsia cespitosa 'Goldtau' · also called Gold dew tufted hair grass, Goldtau hair grass · flowering
Deschampsia cespitosa 'Goldtau' (meaning 'golden dew' in German) is an outstanding cultivar of tufted hair grass, a cool-season perennial grass native to meadows, moorland, and woodland edges across Europe, northern Asia, and North America. 'Goldtau' is prized for its massive clouds of golden-yellow summer flower panicles that catch and hold dew, glowing when backlit. It thrives in cool, moist conditions and grows actively in spring and autumn rather than the heat of summer. Deschampsia species are not listed as toxic to cats or dogs by the ASPCA.
Preferred mix: Moist, humus-rich loam; tolerates moderately acidic to neutral soils
Why gold dew tufted hair grass needs this mix
Gold Dew Tufted Hair Grass flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for gold dew tufted hair grass: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons gold dew tufted hair grass struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives gold dew tufted hair grass weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving gold dew tufted hair grass in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for gold dew tufted hair grass?
Most flowering plants, including gold dew tufted hair grass, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
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 quality bagged compost works for gold dew tufted hair grass in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for gold dew tufted hair grass covers the timing and technique step by step.
