I have a huge bougainvillea that was gifted to me but I can’t make it happy. I put it next to some frosted glass and it wilted so Google said move it to non-frosted glass as it needs more light so I did and it wilted more, so Google said take it outside for a few hours so I did and it almost died. So I put it back next to the frosted glass and it perked up for a few days and then began to wilt again. What does it want?! I only water when the top is dry, its roots are fine and doesn’t need repotting. I like it a lot but it’s driving me crazy.
