I have a foxtail palm tree in front of my home. The palms have been slowly drying up and turning brown the last 6-8 weeks. I currently reside in Florida and we have been facing a cold front the last couple of weeks. I currently have a sprinkler irrigation and water it once a week for about 40 minutes. Sadly I had to cut down the last few branches as they have practically withered away.

Can anyone give me any advice? Will it produce new branches in the spring? Is there anything I...

What an undertaking that journey must have been!

Even though this sacrifice seems a necessary one, sad news nonetheless---mitigated by the intended use of the palm's wood and the propagation of its seedlings.
