When should I trim a hydrangea bush?

[LaydeeBug]

The flowers are a bit past their peak, and I don't know if I should trim them, and if I should, where.

1. As with most flowering shrubs you can deadhead old blooms

You do this just past the bloom head.

Hydrangeas rarely need pruning other than to cut back dead stalks.

Do you have problems with it not blooming well?

3. I haven't planted it yet. Impulse buy

and I really want to get my house painted this Spring. I want to focus on the front gardens when that is done.

2. Thanks for the reminder,

but now have to wait for decent weather! Lots of old/dried 'flowers,' the bush is READY for a trim!

4. Only trim the branches that have bloomed.

Hydrangeas bloom on second year growth, so if you trim it all down at once, you will lose the blooms for the current year.
