I have a tree, which has thorns, I always thought it was a Ceiba. It‘a an old tree. The house was build in 1919, so the tree is roughly that old as well. Recently, I noticed it did not bloom as it used to, and now it has no leaves. The branches fall off easily and inside it’s rotten. I feel a fungus or something else it’s killing it, or it may be too late. Does anyone know what to do, or how can I safe it? Thank you.
