|How do I get rid of the ants without harming the palm?|
I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
most types of ants do not bother plants and therefore do not need to be controlled. However if you wish to get rid of those enhanced most any insecticidal dust or spray will work. Dust the area they are walking through with Sevin dust for example and that should do the trick.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
