I got this bougainvillea plant as a gift a week or two ago. I read up on it and it said that it needed direct light for at least 5 hours a day and not a lot of watering. But I live in central Texas and the days are 100 degrees. I would water it about every other day to two days when the soil looked like it was really drying. For now I have brought it in, re-watered it and now I'm not sure what to do with it.
I want to keep it small and shrub like but from what I understand this keeps growing longer unless you cut it back.
Do I need to cut it back and let it re-grow? Or give it time and let it grow bigger before cutting?
