Troubleshooting
Sword Brake Fern problems — and how to fix them
Sword Brake Fern (Pteris ensiformis) 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.
Faded variegation
Insufficient light washes out the silver band in 'Victoriae'; move to brighter indirect light to restore the crisp contrast.
Browning, crispy fronds
Low humidity or letting the mix dry crisps the delicate pinnae; keep it humid and the soil evenly moist.
Root rot
Soggy, poorly drained compost rots the fine roots; use an open mix and empty the saucer so the pot never sits in water.
Scale and mealybugs
Sap-suckers lodge in the frond axils of compact plants; inspect regularly and treat early with horticultural soap or careful wiping.
