Can soft fruit bushes be transformed by pruning into cordons?
Some time ago, in an excess of gardening zeal, I bought some bare root black, red and white currant and gooseberry bushes. Not having anywhere to plant them at the time, I put them in pots. Several years later, they are still in (larger) pots and have rooted into the soil below..
They are not very big because the location is far from ideal. Recently, I have realised that I am never going to have enough room in my present garden to do them justice as bushes - cordons would be a much more suitable form.
Can these small shrubs be pruned into cordons, or would cuttings trained as cordons be better? I already have a few cuttings taken last winter. My concern about cuttings is their vigour; aren't commercial soft fruit bushes grafted onto different rootstocks?
