I have some splendid Diascia Personata plants, bought from Bodnant Gardens. All through the summer they have had an abundance of beautiful flowers and are at least 4ft tall. I took some cuttings from them in September (late I know) and they are growing slowly in a pot on my kitchen window sill. I want to know: Should I be cultivating them indoors or maybe in my garage where there is a window? Should I nip off the growing tips at the top of the cutting to encourage them to bulk up or just leave them alone? They look quite fragile at the moment and I would hate to lose them. Any advice would be appreciated.
