hydrangeas not blooming

I have 3 small bushes that are several years old that are not blooming this year.  Any ideas why?  They look otherwise healthy.

Winter was too cold for too long. If you look around town you'll notice very few flowers at all. Butterfly Bushes also took a hit. This is second bad year for our hydrangeas and butterfly bush. I'm determined to try to cover them this year so they can rebound. Sad but if the cycle of freezing in the winter continues, these plants may longer grow well here. They used to be bountiful all over town.

Ours hardly bloomed this year. Usually they are laden with flowers. I read that extremely cold weather, like polar vortexes, can cause this.

Last year was a total washout for our hydrangeas (which had bloomed beautifully for 20 prior years). This year they started well, but a cold snap in late spring seemed to set them way back and we had very few blooms. The leaves look nice and healthy, so I hope they may rebound next year. That horrible winter of the early 90s didn't affect their bloom, so I'm hoping.

Same here for 3 years running now.. last two years, it was mostly the long cold winters.  This year we had an early warm spring, followed by a severe cold snap.  Most of the new growth on the mature canes just died off.  Fortunately most gardeners are optimists.  Just wait 'til next year.

Thanks for the comments.  What a shame if we can't grow them in this area!  I also have a 10 year old flowering cherry tree that was completely healthy in the fall and died over the winter.  Could that also be due to the extreme cold?

No blooms on mine but they bloom on second year wood and I ended up cutting them back severely.  Leaf growth is gorgeous despite the extreme heat.  Hoping for improved flowering next year.

This year, we had more than a cold snap in April...we had a deep freeze.  The hydrangeas were developing fine, but the freeze got the buds.  My 20 yr old hydrangeas are somewhat protected, so I did get some flowering.

ALso, make sure your lawn guys aren't 'cutting back' your hydrangea in the fall.  That will surely guarantee no flowers.

If you replace the hydrangea with Endless Summer variety (blooms on old and new), you'll have more reliable flowering.

My linden tree didn't bloom this year, either. I was going to make linden tea with the flowers. Does anyone else have a linden?

I have a huge linden and noticed that it dropped a lot less (leaf? Buds?) of whatever it normally sheds all summer these past two summers. Come to think of it, it shed only a bit this spring, and nothing in the summer. Usually I need to rake and blow the shedded stuff (looks like little leaves with a pod attached) from all surfaces throughout the spring and summer. Sorry, I clearly need to do some research on this tree

after the hail storm in June, Only some ten out of 200 day lily plants bloomed.

One of my hydrangeas was shredded and is treally struggling to survive - it is an endless summer variety, but I don't expect to see flowers

As stated, extremes in temps wreak havoc in plant blooming cycles and general health.  Gardeners must be patient...  it sucks.

This past winter/spring was no problem for some species.

DId you even read your link? http://www.hydrangeashydrangeas.com/wont_bloom.html

your macrophylla hydrangea aka mopheads bloom on old wood. Don't cut them back in the fall - you won't get flowers. unless your mopheads are the Endless Summer variety.
