If that bush is 6 years old it has been sadly underfed. It should be at least three times that size. Once it goes dormant prune it back to 18 - 24 inches tall keeping the same shape since it is nicely shaped. Then fertilize it with 10-10-10 in March, May and July with a quick release fertilizer around the drip line of the plant and water it in well. Make sure that it gets plenty of water in the summer, hydrangeas like moist soil.

Prune in February in south. The way to prune is to thin stalks. Do not top prune. Blooms from old wood.

You are correct.Noni. Google can tell you when to prune. This bush has been pruned too much.Let it go for a couple years. You are cutting next spring buds off. all it needs is food,water and morning Sun.

It might be getting too much sun. I have 2 by my front porch that are partially shaded by a large dogwood tree and they have blooms all over them.

Take a sample of your soil to a good plant store and they could tell you what is missing from the soil. Your local Home Extension department or a Master Gardener should be able to tell you how to care for all of your plants.

It all depends on the type of hydrangea you have some of them grow flowers on old wood and some new wood.

Just to let you know. I have the same problem with plants that has been in the ground (fairly shaded area) for over 10 years. I've experimented with trimming back and not trimming back and over the years only had one flower. They grows prolifically, so I just keep them for the greenery. I had six plants and have removed four of them, none of them ever bloomed. Everything else thrives and performs in the area, so I am pretty sure the soil is not my issue. I just have given up on growing hydrangeas, except for a hydrangea tree in the sunny front of my home which is a real performer.

I would mix a teaspoon of vinegar and a quart of water and water the ground around the bush. Don't get it on the leaves. Coffee grinds sprinkled on ground around bush helps too. This also makes the blooms blue. Check which kind of bush you have to see when to prune and fertilize, and sun/shade requirements.

Hydrangeas typically won’t bloom in highly alkaline soil

Mine are nice and healthy and won’t bloom either. I don’t get it.

Don't cut back. The plant needs acid-loving food and plant in afternoon shade if you have very hot summers. Good luck

Mine are the same exactly as yours

I went and talked to the greenhouses about ours. They said if it was a large leave bush DO NOT trim back.

Thank you for the answers, my daughter has the same problem.

If you see dead-looking stalks coming up out of it, do not remove them or it will not bloom.

Make a habit of dumping used coffee grounds and tea leaves with a pinch of Epsom Salt under your plant. Mulch with shredded oak tree leaves. Plan for exposure to morning sun and afternoon shade if possible. At the very least, make sure it is in filtered shade. My most prolific Bush is planted next to the air conditioner condensation drain pipe. Hydrangea love moist soil.

Mine is the same and it is a bit smaller than yours as the rabbits keep pruning it. Never had a flower.

A friend of mine has gorgeous hydrangea bushes and they bloom beautifully. He said he throws a handful of rusty nails under his plants. I have started doing that and they are beautiful.

The rusty nails change the colour of the blooms, usually pink to blue. Don't think they would do anything to make the plant bloom.
