Troubleshooting
Rochford's Holly Fern problems — and how to fix them
Rochford's Holly Fern (Cyrtomium falcatum 'Rochfordianum') 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.
Overwatering and root rot
Despite its toughness, 'Rochfordianum' is susceptible to root rot in waterlogged soil. Fronds go limp and yellow from the base. Check roots for brown, mushy tissue; trim affected roots, repot into fresh, gritty compost, and reduce watering frequency.
Scale insects
Soft brown scale is the most common pest, congregating along the frond midribs and in leaf axils. Wipe off with rubbing alcohol on cotton swabs; treat heavy infestations with neem oil spray applied every 7–10 days for 3–4 weeks.
Pale or yellowing fronds in low light
Although shade-tolerant, very low light over extended periods causes gradual frond yellowing and reduced vigour. Move to a position with more ambient light or supplement with a cool-white LED grow light for 10–12 hours per day.
