Is the ring on the plant, or on the soil around the plant?

Hi, Joe,

The infestation is on the bark of the tree. There does not appear to
be any infestation in the soil.


I'd wipe it off with a solution of ordinary vinegar, diluted 50/50 with
water. Then, wait & see if it returns. Meanwhile, back off on the water if
the plant has less leaf surface than you think it should.
