I bought a cutting at a plant fair and it has been wonderful in my garden this year. It is now about 1 metre high and 2 metres wide and is still blooming prolifically. We are on the south coast so don't get a lot of frost.
Can anyone advise me whether /when we should cut it back? I have had various suggestions from "leave it alone and let it just carry on" to "cut it back to 6inches from the ground now".
I love it and don't want to lose it by doing the wrong thing!
Lest we forget what we have just lost ....
