Sunningdale Silver Pampas Grass problems — and how to fix them
Sunningdale Silver Pampas Grass (Cortaderia selloana 'Sunningdale Silver') 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.
Cutting blade edges
Long blades have sharp serrated margins. Always wear gloves and protective sleeves when cutting back or dividing.
Outgrows tight spaces
This is a large, wide selection. Give it room at planting; it resents disturbance and is hard to move once established.
Winter dieback / clutter
Foliage and plumes brown and accumulate over winter. Cut the entire clump back hard in late winter or early spring.
Crown rot on wet sites
Heavy, wet soil rots the crown. Plant on free-draining ground and avoid winter waterlogging.
