Gold Dew Tufted Hair Grass problems — and how to fix them
Gold Dew Tufted Hair Grass (Deschampsia cespitosa 'Goldtau') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Summer dormancy and browning in heat
As a cool-season grass, 'Goldtau' may go semi-dormant and look tatty in hot, dry summers; site in partial shade in warmer climates, mulch well, and water consistently — it rebounds strongly in autumn.
Rust and leaf spot diseases
Fungal rust (orange-brown pustules) and leaf spot can appear in humid conditions with poor air movement; thin congested clumps every 3–4 years, ensure good spacing, and remove affected foliage.
