Ponytail palm pests — FAQ
What is eating my ponytail palm?
Ponytail palm's greatest pest threat is scale, which settles on the swollen caudex and along the rosette of long leaves. Spider mites appear in dry indoor air, causing leaf tip browning that mimics drought stress. Mealybugs occasionally colonise the dense leaf base. This plant's drought tolerance makes it easy to confuse pest damage with underwatering.
