My housemate cut my old wood hydrangea back to the ground 2-3 years ago, and after sternly making sure he never does it again (!) I have waited and watched for it to bloom once again. So far it hasn't. I don't fertilize it, and we've had plenty of rain this year, it gets plenty enough sun, but there it sits in all its leafy green glory, refusing to put out a single blossom. How long after such a hard pruning will it take for my poor hydrangea to bloom once again? Would bone meal help?

My plant book says if they are pruned wrong it can take 3 years to come out of it. Meanwhile, I would fertilize it.
You need to prune it after it's done flowering for the season. If done before, it will retard the pruning for a while.
I agree with that to definitely feed them bone meal can not hurt it will feed the roots for you and the old saying is the more roots the more blossoms
