Elijah Blue Fescue problems — and how to fix them
Elijah Blue Fescue (Festuca glauca 'Elijah Blue') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot / centre die-out
The most common issue — clumps naturally die out in the centre after three to four years, or sooner in wet, heavy soil. Divide every two to three years in early spring to rejuvenate, and ensure excellent drainage at all times.
Leaf rust (Puccinia spp.)
Orange-brown pustules appear on blades during humid summers. Improve air circulation by avoiding overhead irrigation; remove affected foliage promptly and thin dense plantings.
