Pumila Dwarf Pampas Grass problems — and how to fix them
Pumila Dwarf Pampas Grass (Cortaderia selloana 'Pumila') 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.
Sharp leaf margins
Even the dwarf form has cutting blade edges. Use gloves and long sleeves when grooming or dividing.
Crown rot in wet soil
Poor drainage and winter wet rot the crown. Plant in free-draining ground or raise the bed; do not let it sit in standing water.
Winter scruffiness
Old blades and spent plumes look tired by late winter. Cut the clump back hard before spring growth resumes.
Reduced flowering in shade
Too little sun cuts plume numbers and loosens the habit. Move to full sun for the best compact display.
