Troubleshooting
Avalanche Feather Reed Grass problems — and how to fix them
Avalanche Feather Reed Grass (Calamagrostis x acutiflora 'Avalanche') 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.
Stripe scorch
The white central stripe can brown in fierce heat or drought; provide even moisture and some afternoon shade in hot climates.
Foliage rust
Susceptible to rust in humid, crowded settings; space for airflow and avoid wetting the leaves.
Reversion
Plain green shoots can occasionally appear; cut them out to maintain the bright variegated effect.
Cut at the wrong time
It grows early, so cut back in late winter rather than spring to avoid removing new growth.
