Troubleshooting
Osmunda spectabilis problems — and how to fix them
Osmunda spectabilis (Osmunda spectabilis) 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.
Drought scorch
Fronds brown and collapse rapidly if the soil dries out. Site at a pond edge, bog, or in a basin that holds water.
Alkaline chlorosis
Leaves yellow in limey soil. Plant in acidic, peaty ground and water with rain rather than hard tap water.
Wind tatter
Tall fronds shred in exposed positions. Give shelter from strong wind while keeping the roots wet.
Slow recovery from division
The tough rhizome resents disturbance and can sulk for a season after splitting. Divide only when necessary and keep divisions saturated.
