Troubleshooting
Pink Pampas Grass problems — and how to fix them
Pink Pampas Grass (Cortaderia selloana 'Rendatleri') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor plume colour
Pink colouration fades in insufficient sun; site in full sun and avoid shading from nearby structures or plants.
Crown rot
Caused by winter waterlogging; plant on a slope or raised bed if drainage is questionable.
Wind damage to plumes
Tall plumes can be battered in exposed sites; stake loosely or site in a sheltered position for best display.
Self-seeding spread
Vigorous self-seeding can cause spread; deadhead spent plumes before seeds set or select female clones.
Scale insects
Occasional infestations on the culms; treat with a contact insecticide or remove affected stems.
