Remove the lower leaves and dip the cut end of the stem in rooting hormone powder. Plant the cutting in a pot filled with a well-draining soil mixture, and place it in a bright location. Keep the soil moist and the cutting should root in about four to six weeks.
3. Division Propagation
Another way to propagate Leucadendron nobile I.Williams is through division. This method involves dividing the plant in half to create two or more separate plants. This process is best done during spring or early summer, before new shoots appear. Gently dig out the plant and use a sharp, sterile blade to separate the root ball into two or more sections. Replant each section in a well-draining soil mixture and water thoroughly.
With proper care and attention, Leucadendron nobile I.Williams can be propagated successfully using these methods, allowing you to grow more of these beautiful plants in your home or garden.
