Pruning dwarf forsythia

19 years ago

I have a 2-year-old dwarf forsythia (Bronxensis) which has flowered beautifully on my Manhattan terrace. I have been told to prune it right after blooming (now). Do I (1) cut all branches back; or (2) cut 1/3 of branches back each year? I have seen both recommended! Many thanks.
