Tanacetum balsamita, commonly known as costmary or alecost, is a perennial herb in the Asteraceae family. Native to Europe and Western Asia, it has been cultivated for its aromatic leaves and medicinal properties. The plant features rhizomatous growth and can spread easily in temperate climates. It has a dormancy period during the winter months.
Tanacetum balsamita thrives in bright, direct sunlight and prefers moderate temperatures. It should be watered when the soil partially dries out, and it benefits from moderate humidity levels. Regular pruning helps maintain its shape and encourages new growth.
土壌
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil has good drainage to prevent waterlogging, which can harm the roots.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10 during the growing season. Fertilize every 4-6 weeks to support healthy growth.
植え替え
Repot Tanacetum balsamita every 2-3 years or when it outgrows its container. Choose a slightly larger pot with good drainage, and refresh the soil mix to provide new nutrients.
伝搬
Propagate by dividing the rhizomes in early spring or late autumn. Ensure each division has a healthy root system and plant them in well-prepared soil.
剪定
Prune regularly to remove dead or damaged leaves and to maintain the plant's shape. Pruning also encourages bushier growth and prevents the plant from becoming leggy.
毒性
Tanacetum balsamita is not toxic to pets or humans. However, it is always advisable to keep plants out of reach of pets and children to avoid any accidental ingestion.
