Q.Hibiscus Plant With Yellow Leaves
What does the yellowing of plant leaves on the hibiscus plant indicate? How does one treat this condition? I recently planted (2) plants here in south central Florida. The plants look great. Dark green color and full of buds and flowers but some yellow leaves with black spots are appearing and will drop off with or without any help from me.

It sounds like your hibiscus has black spot fungus. Treat the tree with a fungicide. I personally like neem oil as it will also take care of any pests on the plant too.
