Troubleshooting
Prairie Dropseed problems — and how to fix them
Prairie Dropseed (Sporobolus heterolepis) 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.
Very slow establishment
Takes two to three seasons to reach its full mounded form from seed or young plants; patience is needed and it should not be judged in its first year.
Flopping in shade or rich soil
Loses its neat fountain shape and sprawls if grown in shade or over-fertilised; site in full sun on lean, dry ground.
Difficult, slow seed germination
Seed is slow and erratic to germinate, often needing cold stratification; many gardeners start with plugs instead for reliable results.
Crown rot in wet sites
Constantly wet or poorly drained soil rots the crown; ensure sharp drainage, particularly over winter.
