I have a question. My concord grapevines were loaded with lots of bunches of tiny grapes. This past weekend the temperature dropped to 24 degrees. Even though the vines were covered with blankets, all my new growth and tiny grapes were destroyed. I am new to growing grapes and this was to be my first crop. I am sure they will produce new leaves, but will the vines produce any new grapes since these were killed while so young?
