Marquette frost damage
We got to 26 F in the vineyard Friday morning. I am a little skeptical about the proper functioning of the thermometer. Damage looked pretty limited. Frontenac was hit the hardest. I would estimate 10-15% bud damage. Marquette was next at 10%, lacrescent was 5-10%.
Most of the other cultivars (st pepin, lacrosse, foch) showed very little damage. Shoots are only 1 to 2 inches right now.
