I understand that there is a thread guiding you on how to LST, but it doesn't answer all my questions. I need to know it you bend the stem at a ninety degree angle or if you're just pulling the stem a little to the side. And do you keep the strings on or do you take it off after the plant is bent?
Just a slight bend. If the branch is new it may bend to 90 degrees, but you don't want to force it. You don't want to damage any of the fibers in the stem. Yes, keep the strings on. Good luck
