Well, if you want some advice straight from the horse's mouth ...... I was at Harrogate Flower Show today and went to ask the lady on Hoyland Plants about caring for Agapanthus in pots, because I had bought 3 Arctic Star plants from them at the Spring Show. She said to put them under cover (shed/garage, greenhouse etc) in November and keep them dry. Don't water them at all. But it may depend on the variety you are growing and where you live.
