Siebold's Wood Fern problems — and how to fix them
Siebold's Wood Fern (Dryopteris sieboldii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Sun scorch
The broad, leathery fronds are particularly prone to bleaching and browning in direct sun or drying winds; always site in sheltered shade and check that overhanging canopy is not lost as the plant matures.
Slow establishment and crown failure in cold wet winters
New plants can fail to establish if planted into poorly drained soil or during cold, wet spells; improve drainage before planting and protect young crowns with a dry mulch of bark or straw in their first winter.
