Skimpy Hydrangea bush

I have a Hydrangea bush in a large barrel. I added more potting soil to it this spring and it grew really bushy and full. Problem is, there's hardly any flowers. One side doesn't have any at all. I've had it for about three years and never had this problem before.
Does anyone know why or what to do next year?

What kind of Hydrangea is it? We have some endless summer ones that I had in a shady spot and they never produced flowers. I moved them to a more sunny spot and now get a few flowers, but still not as many as I would think.

I'm not sure what kind but I think I kept the ID that came with it. I'll look for it and get back to you. It gets a lot of sun as it's in a sunny spot. Last year it had tons of flowers, so don't know what happened to it this year.

It may depend on the variety of hydrangea. There are old wood hydrangeas and new wood hydrangeas. If your non bloomer is an old wood variety and it has been trimmed you won't get much flowering until next year but the bush will be healthy.

Here are two of ours. One is loaded and the other has but a few skimpy blooms. They are old wood varieties and I trimmed one this spring.

I looked for the tag that came with it, but can't find it. It was a gift, so not sure what variety. Looks like your second bush tho. The only thing I trimmed, was last years flower shoots, but nothing else. I don't know what happened to it. Hope next year it does better.

I suspect the flower shoots that you trimmed may have been the old wood the plant needed for blossoms. Against the garage is a morning glory on a trellis that is really healthy but has no buds or blossoms. We're still trying to figure that one out.

BTW the picture also includes the 12K BTU mini split that we use to cool and heat our upstairs.

Oops. I guess I better not trim next year. They looked like old straw sticking up all over the place, lol.

Yep, I noticed that. The Mitsubishi was way too expensive plus the fact that they're backordered for could be months, so I went with Jujitsu. Still pricey, but not as much.

I prune in spring after the stems have budded out for a few days. This makes it easier to spot which ones are living and which are dead and can be removed.

Wear long sleeves. I have about a dozen and can't seem to get through pruning one without drawing a little blood.
