Troubleshooting
Poisson's Nephthytis problems — and how to fix them
Poisson's Nephthytis (Nephthytis poissonii) 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.
Root rot
Most common issue; caused by overwatering or dense soil; repot into a free-draining mix and reduce watering frequency.
Pale or washed-out leaves
Usually too much direct light; move to a shadier spot with filtered light.
Leaf tip browning
Typically low humidity or mineral build-up from tap water; switch to filtered water and increase humidity.
Mealybugs
Check leaf axils; treat with neem oil or isopropyl alcohol applied with a cotton swab.
No new growth
Often a winter rest response or pot-bound roots; repot in spring into a slightly larger container.
