Overdam Variegated Feather Reed Grass problems — and how to fix them

Overdam Variegated Feather Reed Grass (Calamagrostis x acutiflora 'Overdam') 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.

Margin scorch

The white variegation can brown at the edges in intense heat or drought; even moisture and light afternoon shade in hot climates help.

Foliage rust

Prone to rust in humid, crowded conditions; space plants for airflow and keep foliage dry.

Reversion

Occasional all-green or weaker shoots may appear; remove them to preserve the bright variegated effect.

Cut at the wrong time

Being early-growing, cut it back in late winter, not spring, to avoid damaging emerging shoots.
