Maire's fescue problems — and how to fix them
Maire's fescue (Festuca mairei) 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.
Central die-out in older clumps
Like other fescues, mature clumps develop a dead centre after several years; divide every 3–5 years in early spring, discarding the exhausted central portion and replanting vigorous outer sections.
Crown rot in poorly drained soils
Despite being more robust than smaller fescues, it will rot if the crown sits in poorly drained, waterlogged soil over winter; amend heavy clay with grit or plant on a slight slope to encourage water run-off.
Leaf dieback in harsh winters
In zones at the cold limit (zones 4–5) or in exposed, wet sites, outer foliage may bleach or die back in severe winters; the crown is typically undamaged — cut back frosted foliage in early spring before new growth emerges.
Prevent maire's fescue problems before they start
Most maire's fescue issues are care-mismatch, not bad luck. Dial in the basics:
