Many permit the fruit of the vines to perish before their eyes from
the ravages of mildew, ignorant that an effectual remedy is within
their reach. It is simply to dust the branches with flowers of
sulphur. It is best done while the dew is on.
When vines are trained upon the sides of a house or fence, it is well
to whitewash the surfaces on which they are fastened with a wash in
which flowers of sulphur has been largely mixed.
It is recommended by some cultivators to employ such a whitewash for
the _wood_ of the vine, covering all the main stems with it; but all
these methods result in the one thing—the application of sulphur as a
remedy for mildew.
