I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
Cut back any yellow or brown fronds back to where they attach. You can also cut back green healthy fronds if you want to thin out the plant more.
Thanks for the question. Please stop in again soon!
