Troubleshooting
Japanese forest grass problems — and how to fix them
Japanese forest grass (Hakonechloa macra) 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.
Leaf-tip scorch
Browning tips signal too much sun or dry soil; move to deeper shade and maintain consistent moisture with a mulch layer.
Slow establishment
This species is naturally slow-growing; resist the urge to over-feed or over-water to force it, as this causes floppy, weak growth.
Winter dieback confusion
Foliage dies fully to the ground each autumn, which is normal dormancy; cut back old blades in late winter before new spring shoots emerge.
