Golden Male Fern problems — and how to fix them
Golden Male Fern (Dryopteris affinis) 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.
Vine weevil grubs
The larvae feed on fern roots and rhizomes through autumn and winter, causing plants to collapse; apply a nematode-based biological control (Steinernema kraussei) to moist soil in late summer or early autumn.
Frond yellowing and die-back
Premature yellowing of fronds often signals drought stress or compacted, poorly-aerated soil; mulch generously and improve drainage — the semi-evergreen fronds naturally die back in hard winters but should regrow vigorously in spring.
