Troubleshooting Brown Stripes on Zebra Grass

Zebra grass (Miscanthus sinensis 'Zebrinus') often develops brown spots after a wet season, especially if drainage is poor. The discoloration is usually a fungal issue exacerbated by prolonged moisture, not a fatal disease. The plant is resilient and will bounce back next spring.

Immediate Steps

• Remove severely affected foliage to improve air flow.
• Apply a fungicide labeled for ornamental grasses, following package directions.
• Spray in the evening to avoid leaf burn.

Long-Term Fix

If the site stays soggy, consider moving the clump to a higher, better-drained spot early next spring before new growth starts. Alternatively, mound soil beneath the root ball to raise the crown. A simple French drain or a small rain garden nearby can also redirect excess water.

With better drainage, your zebra grass will return vigorous and spot-free.
