Troubleshooting
Ostrich Fern problems — and how to fix them
Ostrich Fern (Matteuccia struthiopteris) 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.
Browning, collapsing fronds in summer
Drought and heat. This fern needs constant moisture and cool roots; keep soil damp and mulch heavily, or it may go dormant early.
Aggressive spreading
Underground runners can colonise a bed. Site where it can roam, or contain the rhizomes with a root barrier.
Scorched fronds in sun or wind
Exposed, dry positions tatter the foliage. Plant in sheltered shade with reliably moist soil.
Fiddlehead food-safety risk
Never eat fiddleheads raw or lightly cooked. Clean off the papery brown scales and cook thoroughly (boil ~15 min) to avoid illness.
