I'm a little perplexed on pruining grape vines in late winter, so let
me tell you what I have this growing season, and I'd appreciate any
suggestions. I use the four cane kniffin system. Currently, each of my
four canes are, I think, one year old and brown in color. From these
canes are brand new shoots, some which have already grown a couple of
feet in length. These new shoots also have some new grapes on them.

This winter, will I remove the brown cane I'm now seeing and use one of
these new shoots (currently green) to replace it? Or, will I continue
to use this brown cane? If I am to remove this brown cane, should I
allow one of these new shoots to grow the length of my wire this
season?

I keep reading that grapes grow on the shoots from one year old canes.
Does this mean that they won't grow from shoots on two, three, four
year old canes? Thanks.

The very best book I have on pruning is an inexpensive book titled "From
Vines to Wine" by Jeff Cox. This will answer all your questions and has
excellent line drawings taking you through several years of pruning.
