How to propagate clump-forming house plants

Find out how to propagate house plants by division, in our step-by-step guide.

Many house plants can be split, or divided into sections and repotted to give you new plants for free. These plants have a sturdy ball of roots at the base of several stems. To divide them you need to remove the plant from its pot and split the clump into sections, which you pot up individually.

House plants that can be divided into clumps:

• Ferns
• Calathea
• Mother-in-law’s tongue
