Digitalis. I have the big Ohia in OL and have had a hard time clearing the guava without killing the Ohia. I dont really know what to suggest. Alot of the trees that I was trying to clear, were also next to the driveway- so the the roots also may have been disturbed by the dozer. I have selectively used poison on the guava. IF you leave the guava, it will basically suffocate the Ohia eventually.
