Most pinching occures on the mail stem but will be effective on the runners. Since the plants seem to be compact & have runners i would leave them alone.

I actually pinched off the runners last year and rooted them. They WAY out performed the �mother� plant.

I would pinch the center and then pinch off the runners just after a leaf node.

Thanks - I was thinking about rooting some of the runners. I am concerned that its a little late in the season to start them, but maybe I can just think of it as a late crop.
