1
Using a pair of secateurs, prune the strongest shoots back to two buds from the rod and cut weak shoots back to one bud (or remove them completely).

Re-tie the main stems (rods) to allow for growth

After pruning, spray with a protective fungicide to kill off any fungal spores from last year, and give a clean start for this year

Finally, if you need to make any large cuts and they start to bleed, cover them with a slice of potato to stem the sap flow.
