Bertie,
I'm not sure, I have just left my vines alone at the moment and am keeping a close eye on them looking for regrowth,recovery, etc.
John,
From what I've read the theory is that the sprayed water has latent heat in it. As it cools on the vine the heat is released which protects the vines. The coating of ice that forms then acts as a shield. It is supposed to protect down to about -2
I've not tried it myself though, don't have enough sprinklers or water pressure.
At least we had a few hours of steady rain last night which is one problem less after our long dry spell.
