Troubleshooting
Bird's Nest Fern 'Crissie' problems — and how to fix them
Bird's Nest Fern 'Crissie' (Asplenium nidus 'Crissie') 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.
Rotting central crown
Water pooled in the nest or constantly soggy soil rots the growing point. Water the soil, not the centre, and let the surface dry slightly between waterings.
Brown frond edges
Low humidity or fertiliser salt buildup. Raise humidity, flush the pot occasionally with plain water, and keep it away from dry heat sources.
Pale or scorched fronds
Too much direct sun bleaches and yellows the broad leaves. Move to bright indirect light; conversely very deep shade slows growth markedly.
Scale insects
Brown bumps cling to the glossy fronds and undersides. Wipe off, isolate, and treat with horticultural oil or insecticidal soap, avoiding the tender crown.
