Troubleshooting
Adiantum venustum problems — and how to fix them
Adiantum venustum (Adiantum venustum) 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.
Crispy brown fronds
Almost always caused by the soil drying out or low humidity. Trim spent fronds, keep the rootball evenly moist and raise ambient humidity.
Pinnae scorch
Direct sun bleaches and burns the fine foliage. Move to dappled shade or bright indirect light.
Leggy, sparse growth
Too much shade combined with poor feeding thins the carpet. Give brighter indirect light and a regular dilute feed in the growing season.
Slow establishment
This species creeps slowly and can sulk for a season after planting. Be patient, keep conditions stable and avoid disturbing the rhizomes.
