Question:

When is the best time to divide chrysanthemums?

Answer:

Early spring is the best time to divide chrysanthemums.  Dig up plants in early spring just as new growth begins to appear.  Divide each plant into sections with a sharp knife.  Each division should contain several shoots and a portion of the root system.  Replant the divisions immediately.  Keep the newly divided plants well watered through spring and summer.
