You might be able to use one other technique for lst with that aerogarden. You can wrap wire around the branches and connect it to the main trunk and then you'll be able to bend the into shape and they wil stay like thatbecause of the wires. After a couple weks they will be hardened in that position. However with this technique you ahve to be careful to inspect the wires and make sure they arent cutting into the stems when they get thicker. Using not so thin wire, and also not wrapping so tightly will help with this. Afterwards, your best bet is to just clip the wires off in sections with wire cutters or something so you don't risk snapping a branch unraveling them.
