Then, insert the cutting into a well-draining soil mix and keep it in a shaded area with regular watering. In about 2-3 weeks, the cutting should form roots and can be transferred to a larger pot or planted in a desired location.
Disease Management
Jaumea helenae Buscal. & Muschl. is relatively disease-resistant, but it may still be vulnerable to certain fungal diseases such as powdery mildew and rust, particularly in humid conditions.

To manage pest infestations, it is important to maintain good hygiene practises, such as removing plant debris and avoiding over-fertilization, which can attract pests. Additionally, natural predators such as ladybugs and lacewings can be introduced to the garden to control pest populations.
If the infestation is severe, insecticides can also be used. However, it is important to choose an insecticide that is safe and effective for the target pest and follow all safety precautions and application instructions.
