Troubleshooting
Giant Sacaton Grass problems — and how to fix them
Giant Sacaton Grass (Sporobolus wrightii) 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.
Large mature footprint
Reaches 1.2-1.8 m across and can overwhelm small beds; allow ample space at planting and cut back hard in late winter to refresh.
Tan winter dormancy
Goes fully dormant and straw-coloured in cold-season climates; this is normal, and the clump should be cut to the ground in late winter before regrowth.
Self-seeding
Can set viable seed and seed around in favourable, moist conditions; remove spent plumes if volunteer seedlings are unwanted.
Flopping in shade
Loses its upright form and splays open in too little light; full sun is essential for a dense, well-shaped clump.
