Gall on blueberry bushes

Asked July 18, 2016, 9:13 AM EDT

Is July too late to spray gall on blueberry bushes w dormant oil spray?

Yes a spray now will not affect the galls and dormant oil now in these hot conditions would burn the leaves and fruit. The timing of sprays to control gall wasp is immediately after bloom has finished with a summer oil.
