Q.Magdascar palm
Magdascar palm is suddenly losing a lot of bark from top of palm. Is it just shedding or has it a problem?

It has always tilted and living in Queensland we have had extreme hot weather this summer. It is in a shady position though. Is there anything I can do or just hope it is okay?

Cold weather might damage a Madagascar palm. It rots and looks like a soft, mushy tissue with a crumpled, withered look.
Your plant has a tilt; has it alway had this or has it developed with the issue? Often times when you see signs of problems on the outside it is beyond saving.
