I have a neglected tree, I believe it is a Hawaiian Umbrella, my mother gave it to me after almost killing it. I have been reading up on ways to maintain it but I am looking for some advice as to the best way to get back into even moderate health. The past few days I have been watering it and keeping it in the sun but its condition actually seems worse. I am also concerned about if it might have a disease.
Any help would be great, I am not even 100% sure about the tree type.
