hi there,
Redcurrents and gooseberries fruit on old growth, so newq growth this year will bear fruit next year. I cut mine back to the size I want it, So I take about half of mine off. taking out any crossin branches and cutting out the one growing into the middle, the reason for this is air flow and to let sunlight in to ripen the fruit. The idea being is to get it into a bowl shape. Cut out dead wood too. I hope this makes sense?
Kind regards Julie
