I have a cuttings frame (pure sharp sand, no bottom heat any more, the element packed up). Now in it at present are a lot of Saxifrage cuttings which were taken late for various reasons (usually 'cos the mother plant was dying on me). Looking today I found that a goodly number of them have rooted. Question is do I leave them until Spring or pot up now and keep the planted ones warm? There is no food in the sand for them, but they are obviously not going to need much until Spring, or are they.
