Ask The Plant Expert:
I have a 3 trunk Robellini palm. On one trunk there is a “hole” that seems to be getting bigger. I have attached a picture. There is no sign of insects or bugs, but I am concerned as it does seem to be getting bigger. What do you recommend? Thank you
Flower Shop Network Plant Expert Reply: Spray with a permethrin or pyrethrin based insecticide, depending on whether its outdoors or indoors, to prevent insects. If there is sponge-like or slimy tissue, it may need a fungicide, otherwise it should heal over.
