All useful advice, but I might add that to flower well, Agapanthus do like to fit snugly into a pot. You'll need to divide them every 5 years or so as if they become too pot bound, then flowering decreases substantially.
It is also absolutely VITAL to wear gloves when handling the roots of this plant, particularly with the roots. The sap of the Agapanthus is toxic and can cause severe stomach cramps. Gloves should be worn at all times when handling earth/commercial garden compost, even if you have had a Tetanus injection.
