Q.Ming Aralia With Tiny Black Hard Oval Objects On Trunks

Zone 10 B coastal southern ca | Anonymous added on May 7, 2021 | Answered

I have at least a 12-year-old six and a half foot Ming Aralia with two relatively thin trunks in a planter. We feed it monthly but have not changed the pebble/soil in many years. There are many very small, black, hard oval objects on both trunks ranging in placement from scattered to dense. I do not see any sign of movement or bug-like features and when I wipe one with my finger it falls off. What are these? Should I be worried? Do I need to treat the plant? How often should a Ming be transplanted? Since the trunks are so leggy, can I cut them, root the existing trunks and not worry about killing the trees?

Here are two links from the University of California that should be helpful. It look like scale, a common pest.

You should be able to prune the tree and root the softwood cuttings.
