I have a large hydrangea in my north facing front garden, i have lived here for nearly two years and it has always produced plenty of large pink blooms. I have always pruned it back to ground level after it has finished flowereing, however this year although there is plenty of foliage there are very few flowers, i have one large bloom that has only just appeared? Am i doing something wrong?

Yes, you should prune it in the spring so the old flower heads etc protect
the young buds from frost during the winter. Then you should only prune out
very old wood (according to you there is none yet) and reduce each young
"cane" just down to the first large bud just below the old flower head.
To prune it to ground level means you are pruning out the flowering buds.
