Hi good morning,
I sent this question last month but did not receive a response, so I am submitting again.
My question is in regard to my 2 windmill palm trees. They are about 5 years old and have been growing very well- this year they showed significant growth; however, this year several of the new shoots/growth has been growing in brown/tan and dead looking/feeling. I'm not sure why this is happening/how to control it.
Please see attached pictures. Thank you for your time!

Hi Kayla and thanks for your question about your Windmill Palm. Sorry you got lost in the system last time! Here's what I found out:
https://blogs.ifas.ufl.edu/citrusco/2023/10/04/foolproof-palm-care-windmill-palm/
So, check the base of your tree to see if there is a growth, in which case you have the fungus and I'm not sure there is a cure.
If it is aphids or scale, you should see some signs on the leaves where the dying parts are. A good spray of water, neem oil or insecticidal soap would then be your course of action.
I don't believe it is a fertilizer issue since the whole plant is not dying at once. It could also be an issue from our freezing temperatures last winter which palms are not really accustomed to. In that case, cutting off the affected branches and protecting it from frost next year would be the route to go.
And finally, a bit of shade cloth on our really hot days might be the answer, as the article says they do not like full sun. Who knew a palm tree would not like full sun!
Good luck with your pretty palm,
