Euphorbia terracina, commonly known as Geraldton carnation weed or false caper, is a species of flowering plant in the family Euphorbiaceae. It is native to the Mediterranean region but has become invasive in other parts of the world, including Australia. The plant is known for its milky sap, which can be irritating to the skin and eyes.
Euphorbia terracina is relatively easy to care for. It prefers bright, direct sunlight and can tolerate dry conditions. The plant thrives in moderate temperatures and does not require high humidity. It is well-suited for outdoor growth in regions with mild winters.
Soil
This plant prefers sandy soil with good drainage. It can tolerate poor, nutrient-deficient soils and does not require rich, fertile soil. Ensure the soil dries out almost completely between waterings to prevent root rot.
Fertilizer
Euphorbia terracina does not require regular fertilization. If desired, a light application of a balanced fertilizer can be applied during the growing season, but it is generally not necessary.
Repotting
Repotting is not typically required for Euphorbia terracina, as it is often grown outdoors in the ground. However, if grown in a container, repotting can be done every few years to refresh the soil and provide more space for root growth.
Propagation
Euphorbia terracina can be propagated by seeds or cuttings. Seeds can be sown in well-draining soil in the spring. Cuttings can be taken during the growing season, allowed to dry for a day to prevent sap leakage, and then planted in sandy soil.
Pruning
Pruning is not generally required for Euphorbia terracina. If necessary, any dead or damaged stems can be removed to maintain the plant's appearance. Always wear gloves when handling the plant to avoid skin irritation from the sap.
Toxicity
Euphorbia terracina is toxic to both pets and humans. The milky sap can cause skin irritation, and ingestion of any part of the plant can lead to gastrointestinal distress. It is important to handle the plant with care and keep it out of reach of children and pets.
