We just moved to Menlo Park and here is a grape vine trained along the fence which appears to call for to be trimmed. When is the best time to trim it, and how?
Cutting from corn plant?
Answers:    The best time to prune back grapes within the South Bay is late winter or hasty spring, before the latest leaf buds break and while the vine is still dormant. There are a few different techniques applied to pruning grapes and an explanation here at Y/A would be comparatively long winded for sure. With that said, I will hook you up to a link from Oregon State University (my older alma mater)...Go Beavs Go!....Oh Sorry, I must of had an ginger & black flashback attack..lol. This link have a very contained by depth explanation along with a nice pictorial of pruning technique to go along next to the whole shebang. Hope this help you out. Have a Happy New Year!

Living in Missouri Wine country give me great opportunity to tour the vinyards. I live about 10 minutes from the nearest wine grower.
Grapes should be pruned during the dormant season, late November to March, that's within MO.
Having lived in the Bay area/San Francisco/Oakland/Alameda for oodles years your dormant period is method later than here surrounded by this state.
In your area planting should be done surrounded by December and pruning as well, adjectives the way to February next to a light summer pruning for a possible hastening of fruit nouns.
