1. Seeds
Bupleurum octoradiatum can be propagated through seeds. The seeds can be sown in early spring or autumn. The plant prefers well-drained soil and is tolerant to a range of soils, including sandy and loamy soils. Before sowing, the seeds should be stratified by refrigerating them at 4°C for one to two months. After stratification, the seeds can be sown directly in the garden or in seed trays. The plant requires moist soil, and germination usually occurs in two to three weeks.
2. Cuttings
Propagation through cuttings can also be done in Bupleurum octoradiatum, and it is most successful when done in late spring or early summer. The cuttings should be 5cm to 8cm long and taken from the semi-hardwood section of the stem.

The cuttings should be kept moist, and rooting usually occurs in six to eight weeks.
3. Division
Propagation through division can be done in spring or autumn. The plant can be divided into several sections from the root ball. Each section must have at least one shoot and some roots. The divisions should then be replanted in well-draining soil and kept moist. Bupleurum octoradiatum prefers sunny locations and requires watering during dry spells.

Disease Management for Bupleurum Octoradiatum
Bupleurum octoradiatum is resistant to most diseases, but certain environmental factors can lead to fungal and bacterial infections. The most common diseases that can affect the plant include powdery mildew, leaf spot, and root rot. Powdery mildew appears as a powdery white substance on leaves, while leaf spot appears as brown or black spots on leaves. Root rot occurs when the roots of the plant are infected, leading to wilted and discolored leaves.
To manage these diseases, proper plant care is essential. Regularly inspect the plant for signs of disease and remove any affected leaves or stems immediately. Avoid overhead watering, as this can increase the humidity around the plant and promote the growth of fungi. Provide adequate spacing between plants to ensure good airflow and reduce the risk of fungal infections. If necessary, fungicides can be used to treat the plant.
Pest Management for Bupleurum Octoradiatum
Bupleurum octoradiatum is also relatively resistant to pests, but certain insects may infest the plant. The most common pests that can affect the plant include aphids, spider mites, and whiteflies. Aphids are small, soft-bodied insects that feed on the plant sap, while spider mites and whiteflies both cause yellowing and wilting of the leaves as they suck out the plant's juices.
To manage these pests, it is important to regularly inspect the plant for signs of infestation. Provide adequate spacing between plants and avoid overcrowding, which can encourage the spread of pests. Natural predators such as ladybugs and lacewings can also be introduced to the garden to help control pest populations. If necessary, insecticidal sprays can also be used to manage pest problems.
