Here in Florida my plants are constantly bombarded beside that annoying White Fly insect and the white, powdery mold or fungus on the leaves. It happens on both my vegetable plants, mini rose plants and my little juniper bonsai trees. How do I go and get rid of both of those problems?

Answers:    Take a solution of weak vinegar and hose, wet a scarf and wipe the leaves down. Your white fly insect problem should disappear (I lived in Hawaii and get these buggers on all my plants). You might enjoy to do this several times before they move out it alone.

For fungus on plants, leave contained by the sun for a day or two, it should execute it. If left alone, the mold will turn black and corrosion your plant.
