The best time to divide an agapanthus is at the end of winter, when the young leaves begin to grow back. This division should only be made on agapanthus that have been grown in the same place for several years. Their tuft is thus large enough to be able to be divided into several large shards, each with their roots.
Agapanthus is the only genus in the subfamily Agapanthoideae of the flowering plant family Amaryllidaceae. The family is in the monocot order Asparagales. The name is derived from Greek: ἀγάπη, ἄνθος.

How often should you divide agapanthus?

Outdoor Care of Agapanthus in Winter

Should I deadhead agapanthus?

As well as prolonging the flowering season, deadheading can improve the appearance of the plant and the garden, and it prevents seed heads from forming.
Will agapanthus grow in the shade?
