My vacation home has fruit trees. Apple, Pear, and Peach. I also have table grapes. They are all showing signs of powdery mildew. They have fruit and the grapes are in bloom. Is it too late to use a sulphur spray? What can I do?

You can use a sulfur spray without harming the fruit. It may be too late to save the leaves, though, if the disease is widespread. It's worth a try, though.
