Frost damage to grapes

The early April cold snap that we had has apparently affected our grape vines (an at least one that I spotted in a neighboring town). The vines were leafing out and looked quite healthy....but, now the leaves are all brown (much like they would look in fall). Some areas of the vine still have new growth on do we help the plant....prune or leave it alone for a while with a wait and see attitude

That question is being asked of many of our fruit bearing plants (and also rhubarb!). Basically, after primary buds are killed on grapes, growers should expect to see secondary and tertiary buds break over the next several weeks, depending on variety. Although the secondary buds generally will produce fruit, the crop is expected to be significantly reduced. Hold off on pruning until you see what the new growth looks like. Good luck!
