I have a hydrangea which shows no sign of flowering this year but is getting quite tall. I was wondering, as it doesn't seem to be flowering now, If I cut it back now will it flower next year?

As far as I know you shouldnt cut it back now, I believe that will stunt next years flowering, wait til next spring and cut off only the dead wood. I'm sure other members will have more advice for you Thumbs up

Welcome! I tip my hat to you. 😁😁😁
Yours may still bloom.
There are two types of hydrangeas.
One that blossoms on new growth.
One that blossoms on last years growth/wood.
Prune in winter, when dormant.
Also in winter fertilize with Epson Salt, every year. Good for them, and keeps blooms to true color.

They do better planted in ground.
If your going to leave in pot.
It should be in at least a 10 gallon pot. Do that after it goes dormant, unless you have cool weather right now.
They prefer morning to afternoon sun. Hot direct afternoon sun, will burn leaves.
Cheer-e-oh ! There Mattie !

Welcome!

Do you know the name of your hydrangea? If not, does it flower white, or blue/pink? Don't cut it back now, at least until we know what kind it is. Pruning a hydrangea that flowers on old wood at the wrong time (such as in winter, sorry Philip, or any other time after it has set next year's flower buds) will cause it not to flower.

My great grandfather had the most brilliant blue hydrangeas in his front garden there in Hertfordshire. Yours looks like it is in a pot, and not a very big one at that, or is that a camera effect?

I don't know the name but the odd thing is, I bought 2 last year both had flowers but as you can see, this year, one has flowered the other hasn't? I thought if it wasn't going to flower this year, if I pruned it now, as opposed to next year in the spring, it might not effect it's ability to flower next year?

It might not prevent it from flowering next year but I'm not certain of the timing of flowering bud setting there in the UK but if your other one is flowering now then it may still be safe to prune (I assume you mean prune in the sense of cutting it back). Usually the pink/blue ones flower on old wood. Ideally, though, it should be planted somewhere where it doesn't need pruning to restrict its size. Is there something different about their locations?

Yes, I do mean cutting back. The flowers have grown on new growth which starts from old. Both containers are about 4 foot apart and I've tried swapping their positions.

It's difficult to answer your question without knowing what hydrangea it is. Being pink it is likely a Hydrangea macrophylla or derived from it. The older ones flowered only on the previous year's wood. There are some newer ones that flower on both old and current year's growth. In those if the old wood buds are killed or pruned off the plant will still flower, but later in the year on new growth. If it is one that flowers only on old wood then if it doesn't flower at the usual time it isn't going to this year. Also if it is one that flowers from old wood only then moving the containers at this stage isn't going to make any difference to flowering this year. I can't grow Hydrangea macrophylla here because of the cold winters although I remember them from when I grew up in the UK. There is a specific Hydrangea Forum on this site, I will submit a request to move this thread there.
