Perennials - Dividing

A certain amount of time and energy is required to create and maintain a well-kept and visually appealing perennial garden. Results obtained from dividing perennials are well worth the time invested. By dividing perennials, a gardener can control a plant’s size, rejuvenate plant growth, and increase the number of desired plants. Signs that a  perennial needs to be divided include:

a. a smaller sized flower than usual;
b. a hole or dead space in the center of the plant;
c. less vigorous plant growth or the plant spreads
beyond its intended space in the garden; and/or
d. bottom foliage is sparse.

It is important to note that some plants do not respond well to division and others need to be divided only if you wish to increase the number of plants. A list of both types of plants has been included at the end of this fact sheet.
