No coral color in coral bark maple
I have a Coral Bark maple and the branches used to be coral in color, but they aren't anymore. The tree has remained very small and is now about at least ten years old. I can send you a picture, if you like. What could be the cause of the lack of color? I don't see any other visible problems. There are some green striations on the bark and some spots but they can't be scratched off.

Coral bark maples lose their bright coral color as they age. The older they are, the less pink the older bark looks. It should still be coral colored on new growth. Are you seeing any new growth? They are slow growing trees, but it is possible a nutrient deficiency is slowing its growth even further and you are not getting much fresh growth. If you do not fertilize it regularly, I would recommend that you give it some fertilizer. If you do not, then this is the issue. Please feel free to send pictures and we can take a closer look.
