There was a Specialist Nurseries Plant Fair at Harlow Carr today, so I trogged along, and who should be there but Mr Agapanthus himself - big Steve, from whom I'd bought my plants a week ago! He said I should pot them on into 6" pots, then when I'm ready to put them in the garden, I should cut the bottoms off the pots and bury them pots and all into the earth "as they like to be snug". That may be anew idea for you WW, tho' I'm sure yours must look magnificent in their pots.
Chicky, I also bought some special Agapanthus food from him which is much higher in potash than tomato food apparently.
