Quaking Grass problems — and how to fix them
Quaking Grass (Briza media) 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.
Flopping in rich soil
Lush, lax growth that splays open results from over-rich or over-watered conditions; grow lean and sunny to keep stems wiry and upright.
Short-lived clumps
Can be short-lived, fading after a few years; divide regularly or allow some self-seeding to maintain the planting.
Winter wet rot
Crowns can rot in heavy, waterlogged winter soils; ensure sharp drainage, particularly on clay.
Tired summer foliage
Foliage and faded seedheads look tired after flowering; cut back spent stems to tidy the clump and encourage fresh basal growth.
