How to Divide Gerbera Daisies Outside

Gerbera daisies, which are perennial flowers, after several seasons of growth may become so thick as to require that they be dug up, separated and redistributed. Such growth is likely, however, only in U.S. Department of Agriculture plant hardiness zones in which winter temperatures never or rarely dip below freezing. In colder climates, Gerbera daisies are treated as annuals: Gardeners pull them from the ground after they are killed by fall's first frost and plant new ones in spring.

Instructions

    • 1

      Spread a tarp on the soil near the location where the Gerbera daisies grow to hold the plant clump after you remove it from soil.

    • 2

      Insert a shovel into the soil about 4 inches away from the outer perimeter of the plant. Drive the blade down as far as possible and angle it beneath the root system to loosen the plant. Pull the shovel up and repeat the same process to loosen and dig up the plant.

    • 3

      Push the shovel beneath roots and transfer the plant to the tarp.

    • 4

      Examine the plant and the root system to determine where to divide it. If you find dead and decaying roots, cut these portions away with a sharp knife and discard them.

    • 5

      Cut away the newest growth from the plant using the sharp knife. Insert the knife between the original roots and the newer growth and cut off the newer growth. Collect the newer offsets for transplanting.

    • 6

      Place the original root clump back into the original hole and add soil back to bury the root system. Tamp the soil down firmly with your hands. Provide water for the plant immediately.

    • 7

      Dig holes deep enough to plant the new offsets. Leave a space of about 12 to 18 inches between each plant and place each plant into the holes so that the crown will be even with or just above the soil level. Add soil to the holes and tamp it down gently with your hands.

      Water the newly planted offsets generously. Keep the plants evenly watered to prevent them from drying out for two to three weeks while they acclimate to the dividing and transplanting.
