How to Divide Hibiscus Plants in Fall

Overview

The hardy hibiscus, also known as the rose mallow can be propagated by division, separating the root ball of a mature plant into separate plants. While separating hardy hibiscus is best done in the spring, fall propagation can be done with a little preparation.

Propagating Plants by Division

Step 1

Dig up the root ball of a large, fully mature hibiscus plant, taking care not to damage the plant. Remove all excess soil from around the roots.

Step 2

Look for areas at the base of the stems to identify places where they can be separated at the roots.

Step 3

Carefully separate the roots of the hibiscus plant by hand, ensuring that there are enough stems in each separated piece to form a new plant. Cut any larger roots with garden shears. Continue this process until all separations are complete.

Step 4

Transplant the new hibiscus plants into containers filled with potting soil and water thoroughly.

Step 5

Place the containers indoors in a sunny area or in a greenhouse to protect the plants. Containers are used because hibiscus will generally not survive transplanting outdoors that late in the year except in tropical areas, such as southern Florida.

Step 6

Transplant your hardy hibiscus plants in the spring, after the risk of frost has passed.
