Bougenvil is beautiful. Moreover, if in a pot or made into a bonsai. However, failure to grow in the pot reaches 100%. Because, its roots are very small, so if just a little shaken to death. To overcome this, when planted in pots, polybags are not removed. But make 4 slices on the side of polybags. Enter the plant into the pot then fill with humus of leaves until full. Avoid using manure because it's too hot for a very small roots. Good luck.
