Propagation of Hypericum majus (Gray) Britt.
Hypericum majus (Gray) Britt. can be propagated by several methods including seeds, cuttings, and division of root suckers.
Propagation by seeds
Seeds of Hypericum majus (Gray) Britt. can be sown directly into pots or beds during fall or springtime. Before sowing, the seeds should be stratified in the refrigerator for four to six weeks. The soil should be kept moist and the pots or beds should be placed in a location with partial shade.

- Anthracnose: This disease is caused by the fungus Colletotrichum gloeosporioides and causes leaf spots and cankers that can lead to premature defoliation.
- Root rot: This disease is caused by the soil-borne fungus Phytophthora cinnamomi and can lead to plant death.
- Stem canker: This disease is caused by the fungus Botryosphaeria dothidea and causes stem dieback and cankers that can lead to plant death.
- Virus diseases: Hypericum majus can be infected by several viruses, including Tomato spotted wilt virus, Tobacco streak virus, and Cucumber mosaic virus, which can cause stunting, mosaic leaves, and other symptoms.
To manage these diseases, it is crucial to practice good cultural practices such as removing and destroying plant debris, proper drainage, and planting in well-drained soil. Additionally, applying fungicides and insecticides can help reduce the impact of these diseases.
Common Pests of Hypericum majus

- Mites: These arachnids feed on the underside of leaves, causing a stippled appearance on the top of the leaves.
- Caterpillars: These larvae of moths and butterflies can defoliate the plant and cause significant damage.
- Leafhoppers: These insects suck plant sap, causing yellow or white stippling on leaves.
To manage these pests, it is crucial to use insecticidal soaps, neem oil, or other insecticides as a preventative measure. Additionally, employing cultural practices such as maintaining proper plant hygiene and using mulch can help reduce the impact of these pests.
