How best to transplant grape vines?
I live in the Greater Seattle area (Zone 8). I have a friend who is redoing his garden and said he will be removing some mature grape vines next spring. These are several types (all seedless) and the vines have trunks that are 1-1/2 to 2" in diameter and about 5' high. When is the best time for me to try to transplant these to my yard, and what procedures/timing should I observe? Thanks.
