After the ant and aphid attack, it appears that the hibiscus plant is again covered with a thick white fungus or mold. This time the mold has made all the leaves of the plant become yellow, wilt and fall off.
At present there are almost no leaves on the hibiscus plant, only branches and white mold are visible.
It remains to be seen if he hibiscus plant will recover from the recent attack.
