Should you prune plants this early after planting - I would say it's definitely established and there is a lot of new growth on it?

It says that it flowers through to late spring so should I wait another month and then prune it?

Any help would be appreciated. I want to keep it nice and bushy and compact but don't want to prune it too soon or too late.

Thank you.

Prune after flowering is the usual thing to do but have a read on the link below, it states **An idea worth considering is to prune whilst the plants are in full bloom** maybe that will give a extra flush of flowers who knows..

Plenty of other info on that link Penny makes interesting reading.. Cheers Misty
