It's more usual to cut them back after they've flowered, Izzy - so earlier than this, in mid-summer. Then you'd get a new flush of leaves and possibly even a few flowers! You can lift and divide them in the spring if they're big clumps.

They are still flowering SH! Is that normal? LOL. They're almost all lying on the ground as they are so straggly...I thought it was odd!

Soooo...leave till Spring then...will do.

Well! They must like your garden! Mine aren't. Boo hoo! ;-)

If you give them a haircut now they should put on new green leaf and look tidy over winter. They will then flower again in spring. I prune my geraniums immediately after flowering and they will often flower again about 4-6 weeks later. If they're leggy then I prune them again about now.

The only ones that don't flower again are G x magnificum. I do cut them back though, as Anchorman says, to tidy them - they grow fresh leaves and look better.

OK....think I'm going to prune them NOW then...they look so straggly and untidy....I'm itching to do so!LOL. I can't bear it!

Thank you both....:-)))
