Does cutting back hydrangeas stop the blooming process for one year? My hydrangeas did not bloom this summer, and I cut them back last fall.

From my experience, I do think so....I have over 15 types of hydrangas....and I cut one type completely down this past fall...will not do that mistake again......I had no blooms on these plants....but all the other types bloomed profusely......hope this helps
