I don't quite get what the site's saying...Does anyone have anything to say about trimming? They are growing crazily!
Basically, let them start growing, then trim low, let the side shoots get high, then trim a little higher than the last trim, let the side shoots get higher, then trim again. the more you trim with most stems, the bushier they get. if you trim them in say a mound shape, the new growth will follow that shape. ect.
