These shrubs flower on last years woody growth, which sprouts after
flowering. The best results I have had came from pruning out older wood and
keeping the plant thinner. Some say that it feels it is under threat and
makes efforts to procreate faster!

i pruned my forsythia hard after it had finished flowering last year but
this year the blooms are much less impressive, despite this method
producing
a fine and compact flowering display the previous year. can you prune it
too
hard? i pruned it harder the last time as it was still growing too fast
and
blocked the light in summer.

I think it flowers on the older wood, so if most of what it is now was
newly grown last year, then those new bits would not have flowered
