Hibiscus plant has leaves again

After the combined ant aphid attack left the hibiscus plant devoid of leaves and covered with a white coating of mold, it appears that the hibiscus plant has regenerated itself once more. Now green leaves are visible on the plant again and some buds may be visible in a week.
It remains to be seen if the ants will again launch their vicious attack on the hibiscus plant to kill off all the flowers and cover it with a white coat of mold
