This video demonstrates the 3 key considerations when it comes top pruning Blackcurrants. You should aim to take out a third of the growth (which should be the oldest), take out any horizontal branches and also clear away the weakest growth of crossing branches. If you are new to pruning then starting with Blackcurrants is perfect because they are so tough and hardy you needn't worry about killing the bush or severely damaging the shape. Blackcurrants are also very easy to propagate :) | Huw Ric
