I have five Albertine rambler roses grown from cuttings taken from a plant which was itself a cutting from my late mother's garden. This is their second summer. They need to be planted out, but the site I have in mind for them is not ready and won't be for maybe a year or two. Can I keep them going in big pots? Has anyone got experience of containing a rambler, known for its vigour, permanently in a pot? I love taking cuttings and growing things on but often fail to know what to do with them then. I have already supplied the neighbours, but because of their source, obviously I want to make these Albertines into a feature. Any advice and ideas welcome, please.
