Troubleshooting
Blue Wild Rye problems — and how to fix them
Blue Wild Rye (Elymus magellanicus) 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.
Winter rot
Wet, poorly drained soil over winter rots the crown; plant in gritty, free-draining ground and avoid waterlogging.
Heat and humidity decline
Struggles and may die out in hot, humid summers; site in cooler, breezy positions and treat as short-lived in warm regions.
Colour fade in shade
Blue foliage greens and the plant flops without enough sun; give full sun for best colour and posture.
Short lifespan
Often short-lived, declining after a few years; divide regularly or replace, and propagate to keep stock going.
