Troubleshooting
Sugarcane Plume Grass problems — and how to fix them
Sugarcane Plume Grass (Erianthus alopecuroides) 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.
Flopping in shade or rich soil
Stems lean and the clump opens up when grown in too much shade or over-fertilised. Plant in full sun on average soil and skip heavy feeding.
Rust fungus
Orange pustules can appear on leaves in humid, crowded conditions. Improve air flow, divide congested clumps, and remove badly affected foliage.
Leaf scorch in drought
Being a moisture-loving species, blades brown at the tips in prolonged dry heat. Water deeply during droughts and mulch the root zone.
Slow spring emergence
As a warm-season grass it stays dormant until soil warms, looking dead in early spring. Delay cutting back until new growth shows and be patient before assuming loss.
