Troubleshooting
Naomi Hakone Grass problems — and how to fix them
Naomi Hakone Grass (Hakonechloa macra 'Naomi') 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.
Scorched variegation
Bleached or crisped white-gold margins indicate too much sun or dry soil; move to part shade and maintain even moisture.
Loss of autumn colour
Weak rosy tints stem from deep shade or over-feeding; brighter dappled light and lean feeding restore the autumn flush.
Slow to fill in
Naturally slow-growing; over-watering or over-fertilising to speed it up only causes weak, floppy blades.
Winter dormancy
The plant dies back to ground level each winter and may look dead; cut old foliage in late winter before new shoots emerge in spring.
