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.

Plant type: flowering

The reasons goldtau tufted hair grass isn't blooming

Almost every non-blooming goldtau tufted hair grass traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding goldtau tufted hair grass a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get goldtau tufted hair grass to flower

Maximise sun. Give goldtau tufted hair grass the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for goldtau tufted hair grass and get the feeding right with the goldtau tufted hair grass fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Goldtau Tufted Hair Grass flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
