I have found that using a length of the stretchy green garden tape (that is about a half inch wide) and a binder clip is a simple way to widen the side leaves of your plants. I use a length of tape that will stretch from the pot rim and up and over the branch I want to train and down to the pot rim. I hold both ends of the tape and pull down gently. When you are happy with the branches new location, clip both sides of the loop to the pot edge with a binder clip. With this method it's easy to increase or decrease the restraint. I usually pull the four main side branches down gently and stop. Then return the next day and pull down a bit more, The soft green tape doesn't damage the plant.
