Hydrangeas

Usually my hydrangeas are beautiful but some years there are very few or no blossoms. I do not trim in the fall so the old wood stays for new growth and buds. What could be the problem? I do use coffe grounds for fertiluser. Thank you.

In all likelihood, they are getting frost nipped. This has happened in the Northeast-if you don't have a variety like Endless Summer, a frosty spring can kill the buds.
What is you location?

We live in Minnesota, and I always cut down my hydrangeas to about 6-8 inches in the spring. An old master gardener told me that if a plant has to try to "revitalize" old wood, it takes strength away from allowing it to blossom. I have SUCH large blossoms on all mine, so I think he knew what he was talking about!
thank you. I will try this next year since mine are already budding.
