Thapsia garganica, commonly known as deadly carrot or turpeth, is a perennial plant in the Apiaceae family. It is native to the Mediterranean region and prefers subtropical climates. The plant is known for its large, yellow umbel flowers and can grow up to 2 meters in height. It has a dormancy period during the cooler months.
Thapsia garganica requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers a relatively dry environment. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. Maintain moderate humidity levels.
土壌
Thapsia garganica prefers well-draining loamy soil. Ensure the soil has good drainage to prevent waterlogging, which can lead to root rot. A mix of garden soil with sand and organic matter works well.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant during the growing season, typically in spring and summer, to promote healthy growth and flowering.
植え替え
Repot Thapsia garganica every 2-3 years or when it outgrows its current container. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, shake off excess soil, and place it in the new pot with fresh soil mix.
伝搬
Propagate Thapsia garganica through seeds or root division. The best time to propagate is in early spring. For seed propagation, sow the seeds in a well-draining seed mix and keep them in a warm, bright location. For root division, carefully separate the roots and replant them in individual pots.
剪定
Prune Thapsia garganica to remove dead or damaged foliage and to maintain its shape. Pruning is best done in late winter or early spring before new growth begins. Use clean, sharp pruning shears to make clean cuts.
毒性
Thapsia garganica is toxic to both pets and humans. All parts of the plant contain toxic compounds that can cause skin irritation, gastrointestinal distress, and other symptoms if ingested. Handle the plant with care and keep it out of reach of children and pets.
