Troubleshooting
Roosevelt Fern problems — and how to fix them
Roosevelt Fern (Nephrolepis exaltata 'Rooseveltii') 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.
Brown, crispy frond tips
Almost always caused by low humidity or inconsistent watering. Raise humidity above 50%, keep soil evenly moist, and trim affected tips with clean scissors.
Yellowing fronds dropping
Caused by overwatering, poor drainage, or root rot. Check that the pot drains freely, reduce watering frequency, and ensure the plant has adequate light and warmth.
Scale insects or mealybugs
Small brown scales or white cottony clusters on frond undersides and stems. Remove manually with a cotton swab dipped in isopropyl alcohol; treat with neem oil or insecticidal soap.
