I tried to branch my Plumeria and cut it into two Pieces. The upper part I planted in soil and it grows beautifully. But the other part which I tried to branch just built some pimples, which I thought these could be the new branches. But thats it.. That was in September now its June. Nothing has changed, still the same pimples but No branches. Please, can anybody tell me what I have to do. Many thanks, Änny
