Can anyone tell me what is wrong with this Schefflera? It is planted level with the lawn / mulch, has not been observed to have been subject to insect attack, and the black doesn't rub off. Any help will be appreciated!
Thanks!
P.S. I also posted on California Forum just in case it is a problem common to my State.
