Hi there. I got the bug this spring to make wine so for fun I planted my first vines. Ok so I only planted 6 of them but so far they are growing really well and now I want to plant more. Is it possible to split a vine? If so, how and when? It might be better in the long run just to buy more although I thought I would ask.
If anyone can suggest any sites or books to read that would be great as well.

John,
It's easy to propagate grape vines if they're not grafted, but a little problematic if they are.
If you have abundant strong canes growing now, you might be able to bend one (or more) down, bury a node in the soil, and start a new vine by layering. Next year, transplant it or leave it in place as needed.
Another way is to take hardwood (one year old) cuttings next spring (the prunings you would burn anyway), and root them. Cuttings should be 3 or
4 nodes, and __planted bottom down__ , burying one or two nodes.This takes longer to get a new vine than layering, but you can get dozens of vines from the prunings of one vine.If you want to propagate grafted vines, you've got to propagate both parts, by starting new rootstock vines and then grafting the scion material onto that the next year. Time consuming and tricky and not for beginners.
