old grape vine
Transplant an existing old grape vine. How much of the root system do we need to dig up?
Clackamas County Oregon
Dig up as much as you can. The real trick is to cut back the top about as much as you have cut back the roots. If you transplanted all the roots, you could keep the entire top. Half the roots then half (or less) of the top...... And don't try to harvest grapes the first year or two. Once the vine has gotten over the transplant shock and reestablished itself then you can begin to set more buds and/or harvest grapes.
