Root Division

Many clumping perennials that develop a thick mass of roots—including hosta, daylilies, daisies, astilbe, and Siberian iris—can be divided to make more plants when they are starting to leaf out in spring or before they bloom. Consult a garden encyclopedia to learn when you should divide any particular plant; some species should be dormant, others need to be in active growth.

Step 1
Using a garden spade, dig up the plant with as big a root ball as you can manage.
