Hydrangea explosion

As06111

Help! I've had a hydrangea explode on me, its grown massively this summer. I deadheaded it two years ago but left it last year. It started out this year very neat with a heavy load of blooms on. However  an unusual amount if sunshine along with a usual amount of rain has seen a lot of stalk growth. I plan to wait until the flowers are dead but where should I trim it back to? Any advice greatly appreciated. Thanks

Hello @As06111, welcome to the forum 
It depends very much on which type of hydrangea it is, but you may find the link below useful. 
If you're not sure,  if you post a photo it will help us to identify it.

They are very large plants, the ones I cut right back to the ground last April are already at least 4’ tall and even wider. That’s what hydrangeas do. They done explode, they grow. 
take a look at this one, about 6 or 7’ tall and must be around 12’ or more feet.


These cut back right to the ground last April,

Thanks Philippa,  the chop down did them good.

Lyn I am so jealous. Having to grow them in pots mine stay small and clearly will never give the impression yours do.

They do grow so well here, combination of having room to spread and the acid soil.
