Answer: I think you're on the right track in pruning as you have, but you'll need to be just a little more patient with your bougainvillea. These plants have cycles of growing and resting and flowering which they repeat up to 6 times a year. When it's time to put out new growth, it should send out new shoots at the site of the injury (pruning cut). Aside from pinching the tips of the growing branches out to stimulate new growth behind the pinch, you really can't direct the new growth - it may not appear exactly where you want it to appear - at least for a year or two. In the meantime, enjoy your bougainvillea!
