Troubleshooting
Purple Love Grass problems — and how to fix them
Purple Love Grass (Eragrostis spectabilis) 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.
Crown rot / root rot
The most common problem in clay or amended soils with poor drainage. Ensure sharp drainage; avoid mulching tightly around the crown. There is no rescue once rot is advanced — prevention through soil selection is essential.
Self-seeding aggressiveness
Seeds disperse prolifically when the panicle detaches in autumn. In garden settings, deadhead or cut stems before seed fully ripens to prevent unwanted colonisation of neighbouring beds.
Flopping / lax stems
Caused by excessive soil fertility, shade, or supplemental irrigation. Grow in lean, sunny, dry conditions to maintain compact, upright form.
