You’re welcome! Great to hear your gardenia is responded well to the treatment :).

I think that’s what it is… Mealy bugs. Yesterday I treated it with a spary of 50% rubbing alcohol to 50%water + 3 tsp of Dawn liquid detergent. Sprayed the plant and wiped off as much of the infestation as I could, Then sprayed it thoroughly with the water hose. Will repeat in three days. I have my finger crossed. Thanks PS – It looks very good today with no wilt or leaf drop.

I can’t see clearly to be certain, it is possible your plant is infested with a type of mealybugs. Link below with numerous species, maybe you can find a match? Best wishes! https://firstdetector.org/static/pdf/mealybugs.pdf
