If the gooseberry and blackcurrant look like canes, they need formative pruning but not now. The blackcurrant I would prune down to six inches at the end of July. Gooseberries are winter pruned.
They will do far better in the garden. My blackcurrant bushes are five feet across and loaded, they would not be in a pot.
