I have a blackcurrant that (bless it!) has been living in a pot since I got it for Christmas. We were moving house in the new year and then it just took longer than expected to sort the garden and get it planted. It’s gone in the ground today. Everywhere I read says to prune it back to about 2 inches from the ground when first planting out. It already has lots of new growth and some buds. Do I still need to prune it or is it best left for this season?
