Troubleshooting
Intense Blue Fescue problems — and how to fix them
Intense Blue Fescue (Festuca glauca 'Intense Blue') 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.
Centre dieback over time
The tuft hollows out after a few seasons. Divide every two to three years, keeping the healthy outer growth to maintain a full dome.
Rot from wet feet
Damp, poorly drained or humid sites rot the crown. Use sharply drained, gritty soil and full sun with good airflow.
Loss of blue in shade
Inadequate light turns the foliage green and the form floppy. Relocate to the brightest spot to restore the intense colour.
Heat-induced browning
A cool-season grass that may brown in peak summer; trim tatty foliage, water lightly, and it greens up as the weather cools.
