White-Like Powder Stuff on Plant in Pot

Anonymous added on March 18, 2011 | Answered

I have a gardenia plant and it has white-like stuff on it, some where the buds should be.  I have it in a pot, not in the ground. Also, something is eating the leaves, and some leaves go yellow. It had only four flowers on it when I got it, but they have now gone. Can you please give me help with this?

The white powder is powdery mildew. This article will help with that:

It is hard to say what pest is eating the leaves, but we have found neem oil to be effective against most pests. Here is more information on that:

The white-like stuff is a pest called whitefly. This will require spraying of a pesticide in the early morning or late evening.The spraying should be done soon to avoid death of the plant.
