I have beeen to the data base, and search several pages here but still have a few questions. I received about sid cuttings last fall and kept them alive and thriving in the greenhouse all winter long, one 'stick' has split to two main branches and is about three foot high and looking very good, the others are doing ok as well some not quite as tall. I can't remember therir names other than Versi Peach, and I think one was yellow, and one pink...when should I exspect to see buds forming? SHould I pinch the tops if they have already two main branches? I know they like to eat and drink often, but how large of a pot should they be placed in?
