Yeah, the wind is a real killer with macro isn't it.
Just to clarify my earlier comment regarding reducing shutter speed - I don't mean have a slow shutter speed, but as the exif shows 1/800 af f4, I would think you'd be able to increase your DOF a bit by reducing shutter speed a couple of notches and upping the aperture accordingly.
And Damage's comment about using flash is a good one too, as it means you can use a smaller aperture. Check what flash sync speed you can use though, I think my camera is only up to 1/320 sec.
