I see dozens of clusters on my two grape vines, but not enough bees as they begin blooming. I know they're supposed to be hermaphrodites, but is there anything I should do to get maximum pollination? I'm thinking about how people shake tomato blossoms... think that's worth a try?

Grapes are wind pollinated, not bee pollinated so maybe shaking the vine would help. Have you had a problem in the past with grape pollnation? Maybe your grapes haven't bloomed yet and you just need to be patient.

Oh, okay, good to know. They're just starting to bloom now, and in past years most of the clusters fall off afterward. I thought it could be some disease, since one of them gets a fungus every year, but the other seems immune to it, and I still lost most of the clusters. This year I worried they might not be getting properly pollinated. But we have plenty of breezes, so I'll see what happens.

Any recommendations to prevent the rusty fungus?

When I grew grapes, I always dormant sprayed with a mix of copper sulfate and horticultural oil. If you do it at least twice a year (fall/spring or early spring/late spring), it cuts down on mildew, fungus and overwintering bugs.
