Transplanting established grapevines and berries

Asked August 23, 2018, 4:47 PM EDT

I work at a summer camp, that has an abandoned garden, and a newly established farm. The abandoned garden has grapevines, currants, and raspberries. I'd like to transplant 3 grapevines (rootstock and all), 1 currant bush, and 3 raspberry canes into the farm. I am wondering what the best time of year to do this is? Should the plants be pruned back before transplanting? Months before transplanting? After transplanting? Do they need to be transported in containers, or can we wrap their roots up (they are only traveling a short distance).

They could all be transplanted in the fall or early spring.
Fall transplanting allows the plant to get in some good root growth before the soil get to cold. It will also reduce winter hardiness. Since we are going into an El Nino winter, the winter should be warmer and drier than normal whatever that means here in Michigan. Winters have become quite variable here in Michigan..
They should all be pruned when you transplant them. You can cut them just before you dig them up as they will lose a lot of roots.
For the currents cut off half of the older canes and leave all the young ones.
For the raspberries, Pick a shoot that grew this year and dig it up. Replant it and cut off the shoot. You should get new primocanes in the spring.
For the grape cut off all the old canes and arms. leave about four shoots that grew this year as close to the trunk as possible. Leave about 8 buds on each shoot. Dig up and replant the trunk. Use the new shoots to reestablish the arms in the new trellis.
My personal opinion is that given a mild winter Late February would be a good time to transplant in Southeast Michigan.

we generally do not recommend transplanting raspberries because of the danger of moving plants that are infected with plant viruses. We recommend planting new virus free stock purchased form a certified nursery.

Thank you so much, this info is very helpful!
