Troubleshooting
Pink Pampas Grass problems — and how to fix them
Pink Pampas Grass (Cortaderia selloana 'Rosea') 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.
Faded pink colour
The pink is subtle and strongest in cool, bright autumns; warm spells and shade wash it to cream. Site in full sun and expect colour to vary by season.
Sharp leaf edges
Blades have cutting serrated margins. Wear gloves and long sleeves when handling or cutting back.
Self-seeding / invasiveness
Can naturalise in mild coastal areas. Remove plumes before seed disperses where it is a recognised weed.
Winter clutter and crown rot
Spent foliage browns over winter and wet soil rots the crown. Cut back hard in late winter and plant on free-draining ground.
