Don't feed it anymore, you should have flower next year.

And, try not to be tempted to prune it now, you may cut off next year's flowering stems. Give it a feed in the spring and it should flower next year.

You aren't the only one, mine didn't flower, neither did my dads and they are usually so reliable.

No flowers for me either. My hydrangeas suffered from bad frost this winter, think I'm lucky they even survived. Plants look healthy now but alas no flowers.

Be sure to give good frost protection this winter, if it turns out as predicted. The flower buds for next year are forming now, so you will need to protect those branch tips over the cold seasons.

I'd ask how long you've had the plant, whether you've ever pruned it and if so, when. Also, which variety of Hydrangea is it?

Good plan Tug, I will protect them.
