Paul:
I hesitate to get into this, but seeing the pictures...
Am I correct that these are the dwarf Burtt Davyi ficus?
Last July, I brought back one from Florida that had a fungus problem. (Only the dwarf BDs seem to get this.) I was unable to save the tree.
When you cut away the part that's bad, the cut discolors rapidly to the same color, and, well you get the picture. I don't recall black spots on the leaves.
I would either PM dbz12fan (Charles Bevan) or call Jim Smith (or his son, Doug at Dura-Stone (772) 562-5291
to get authoritative answers. Please share what you learn here.
They're lovely trees, but that fungus is a bummer!
