A few years ago we bought a gooseberry and a black currant bush and kept them in Jón's garden. They grew fiercly the last years and the birds were happily taking care of at least the black currants. 
When changeing a few things in the garden I got the idea to move the berrybushes and plant them where the hedge next to the walkway had been. I had purchased a red currant bush, too, so perfect to put the three of them there and some lilac inbetween (hope the lilac will survive the winter).
But to replant those 2 bushes I first had to get them out of the ground and give them a proper trim. To make a long story short, there wasn't much left of them when I was finished, but I hope they'll grow strong next spring.
