I pruned in the first week of April, and within a day or two, buds started to swell. They leafed out the day after the last week's crappy cold spell passed. Now we're looking at another dip toward freezing on Thursday and Friday nights. I always thought 28 degrees was the danger point for St. Vincent, but I can't find that number anywhere.
If anybody is worried, please let me know.
I did find some encouraging words at Extension.org:
Pruned vines have earlier bud burst than unpruned vines, so delayed pruning is an effective strategy for delaying bud burst and reducing risk of frost injury.
As a procrastinator about pruning, I might have done my vines a favor.
