how to train bougainvillea?
I planted a fairly small fuschia/pink bougainvillea, and it's grown quite a lot, with many "branches" (not sure what to call them). How do I train it into a more tree-like appearance instead of bushing out horizontally as it is now? I'm in central FL, and have been inspired by a gorgeous one near here, which has a big single "trunk", and a huge always blooming top over an entryway. Obviously I will have to trim some branches, but how do I know which ones to cut, and when to cut, (during which season or during blooming)? I'd appreciate any help or suggestions please!
