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.
