Troubleshooting
Giant Sacaton problems — and how to fix them
Giant Sacaton (Sporobolus wrightii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
The most common failure in cultivation is excessive irrigation or poor drainage; yellowing and basal dieback are early signs — cut back watering immediately and improve drainage.
Rust fungus
Orange pustules from rust fungi (Puccinia spp.) can appear on leaves during humid summers; improve air circulation and avoid overhead irrigation; no fungicide is usually needed.
