Wines I'm Making: A Dilemma

Finally, the weather has cleared. It now seems safe to say that summer is here and that the chance of further rains is negligible. Time to spray the grapes again with sulfur to prevent mold from forming on the plants. With that in mind I went out to inspect the small vineyard out back yesterday and was both happy and dismayed to see that the vines are in full bloom (grape flowers are not much to look at, but without them there would be no grapes and no wine). The problem is, spraying the vines while in bloom runs the risk of seriously reducing fruit set. That's to be avoided, but the vines do need protection. I've decided to wait, however, as the weather remains fairly cool, there is still some sulfur on the vines (not ALL of it was washed away by the rains), and there has been a decent breeze the past few days. I will wait until flowering is finished to spray. I hope that will prove to have been the right decision.
