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.

Growth habit: Tidy, clump-forming mound of fine dark-green leaves sending up slender stems carrying a delicate cloud of flowers that shift from bronze-red to gold.

What fertiliser goldtau tufted hair grass actually wants — and why

Goldtau Tufted Hair Grass is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for goldtau tufted hair grass: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed goldtau tufted hair grass, and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For goldtau tufted hair grass:

Low feed requirement; a spring compost mulch or one light balanced feed sustains it. Skip rich nitrogen feeds that promote floppy growth and dull the prized flower colour. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when goldtau tufted hair grass is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for goldtau tufted hair grass

Half strength is the safe default for goldtau tufted hair grass — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Feeding always goes onto already-damp soil, never dry roots — water goldtau tufted hair grass first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the goldtau tufted hair grass watering schedule.

Signs you are over-feeding goldtau tufted hair grass

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for goldtau tufted hair grass:

Signs you are under-feeding goldtau tufted hair grass

If the symptoms point at watering, light or roots rather than nutrition, the full goldtau tufted hair grass care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of goldtau tufted hair grass with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.

Organic vs synthetic feeds for goldtau tufted hair grass

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.

Synthetic / liquid feeds

A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Half strength is the safe default for goldtau tufted hair grass — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding goldtau tufted hair grass look like?

Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding goldtau tufted hair grass year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.

Should I flush the soil of goldtau tufted hair grass?

Flush the pot of goldtau tufted hair grass with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
