However, succulent green shoots are much more sensitive to low temperatures, so spring frost damage is serious concern. Damage from spring frost can vary within and between vineyards. Some factors that determine the extent and severity of frost damage include vineyard location, stage of shoot growth, the minimum temperature reached, and the duration of time that the tissues are at......
