Troubleshooting
Hare's Tail Grass problems — and how to fix them
Hare's Tail Grass (Lagurus ovatus) 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.
Lax, floppy growth
Rich soil or low light produces tall, weak stems. Grow in lean, well-drained soil in full sun.
Poor seed head formation
Excess nitrogen or shade reduces the quality of the fluffy heads. Avoid fertilising and ensure full sun.
Rust disease
Orange rust pustules can appear in humid conditions. Improve air circulation and remove affected stems promptly.
Overwatering
Root rot sets in quickly in wet, heavy soils. Ensure the container or bed is free-draining and reduce watering in cool weather.
Short lifespan
Lagurus ovatus is an annual or short-lived perennial and declines after flowering. Collect and sow seed annually to maintain the display.
