Answer: For the most part, creeping fig clings to walls and grows slowly enough that if it begins to reach out to cover other plants you should be able to redirect the growth by pushing the stem back towards the wall and away from adjacent plants. However, you'll need to monitor the growth of creeping fig periodically. So, if you regularly visit your garden and keep a watchful eye out for errant stems and branches, the creeping fig should not overtake your bougainvilleas. If you do not regularly spend time in your garden, I'd be afraid that the creeping fig would take over and become a tangled mess. So, the answer to your question really depends upon how much time you're willing to spend to keep your vines under control. Best wishes with your garden!
