I just moved into a new apartment in Boston, and as a housewarming gift a friend sent a beatiful Bougainvillea Bonsai with tons of gorgeous magenta bracts. It stayed healthy for about a month, but then the bracts started getting white and yellow splotches along the edges and then they ALL started to drop. There are only a few bracts left! What's wrong? I have heard that Bougs like to dry out between waterings, and think I may have been overwatering. It gets a few hours of bright sunlight in the morning, but unfortunately I can't put it outside since I'm in an apartment. Will it be able to thrive at all? Am I doing anything else wrong? The leaves still look healthy, so I am wondering if it is just going through a non-flowering phase. Please help, I want my blooms back! Thanks!
