I have been researching this for a few years and can't solve why my hydrangeas won't bloom.
- I have tried not pruning - didn't work
- I have tried not pruning and protecting over winter with leaves surrounded by burlap - pics attached show this doesn't seem to have worked.

Pics attached are this year and again, I see no blooms. The first two are unidentified but the third, which is a row of three Teller Blue macrophylla. I am thinking of trying fertilizer just because I haven't done it yet.

Any ideas anyone?
thanks!
