Sium latifolium, commonly known as Greater Water-parsnip, is a perennial plant in the Apiaceae family. It is native to Europe and parts of Asia, typically found in wetland habitats such as marshes, riverbanks, and ditches. The plant has a robust growth habit and can reach up to 1.5 meters in height. It has a dormancy period during the winter months.
Greater Water-parsnip thrives in temperate climates with moderate temperatures. It requires bright, direct sunlight for optimal growth and prefers high humidity levels. Regular watering is essential to keep the soil consistently wet. The plant can tolerate a range of temperatures but prefers cooler conditions.
土壤
Sium latifolium prefers loamy soil that is consistently wet or even waterlogged. Good drainage is not a primary concern as the plant thrives in wet conditions. The soil should be rich in nutrients to support its robust growth.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 is recommended. Fertilize the plant during the growing season to support its vigorous growth. Apply the fertilizer every 4-6 weeks.
换盆
Repotting is generally not necessary for Sium latifolium as it is typically grown outdoors in its natural habitat. However, if grown in a container, repotting should be done in early spring before the growing season begins. Ensure the new container has ample space for root growth and is filled with nutrient-rich, loamy soil.
传播
Propagation of Sium latifolium can be done through seeds or division. Seeds should be sown in early spring in a wet, loamy soil mix. Division can be done in early spring or late autumn by separating the root clumps and replanting them in suitable wet conditions.
修剪
Pruning is required to maintain the plant's shape and encourage healthy growth. Prune back any dead or damaged stems in early spring before new growth begins. Regularly remove any spent flowers to prevent the plant from self-seeding excessively.
毒性
Sium latifolium is not known to be toxic to pets or humans. However, as with all plants, it is advisable to handle with care and avoid ingestion unless properly identified and deemed safe.
