Frost sprinklers (1st of 2)

Frost sprinklers

Frosts can destroy vines and the grape crop. Many growers use water sprinklers to protect their plants when frosts are forecast. When water freezes on the vine it releases latent heat, keeping the growing buds or grape berries at a temperature where damage does not occur. These sprinklers are in the William Hill vineyards, near Alexandra, Central Otago.
