I have repotted a fairly large bougainvillea which is on my deck. Every winter I have to bring it in as it won't survive the cold in Ontario, Canada. How do I treat it for bugs. I don't want little flies hatching out of the soil in my home.
Also, if you think it would survive in my garage, which gets down to 30 below C, please let me know. I'd rather not have it in the house if at all possible.
