If you`ve got to get them out now, then the more top you cut away, the better the chance they have of surviving - particularly if you can keep intact as much of the rootball as possible (actually `rootball` is a bit of a misnomer, as they will probably have long straggy roots going out in all directions ). If your friend can get them in the ground while it`s still wet so much the better. Tell your friend to mix a good dollop of bonemeal in the planting hole, not to let them dry out, and after a week or two to give them a light dressing of sulphate of ammonia to help them form some new growth. They won`t fruit next year, of course.
