Cultivation Methods for Achillea Ligustica All.
Achillea Ligustica All. thrives in well-drained soil and can be cultivated in full sun or partial shade. The ideal soil pH range is 6.0-7.0. The plant can be propagated through division, seeds, or cuttings. Division should be done in the spring or fall. Seeds should be sown in the fall or early spring. Cuttings can be taken from the stem tips in the spring or summer.
Watering Needs for Achillea Ligustica All.
Achillea Ligustica All. requires moderate watering, and it is crucial not to overwater the plant. The soil should be kept moist but not waterlogged.

Propagation of Achillea Ligustica All.
Achillea ligustica All., also known as Ligurian Yarrow, is a herbaceous perennial plant that belongs to the Asteraceae family. Propagation of Achillea Ligustica All. can be done by following different methods, including:
Seed Propagation
One of the common methods of propagation for Achillea Ligustica All. is through seed propagation. Seeds can be collected from mature plants by waiting for the flower heads to dry and then collecting them. Once the seeds are collected, they need to be stored in a dry and cool place until the time of sowing. The soil needs to be fertile and well-draining and should be prepared by mixing organic matter such as compost or manure. Sow the seeds lightly and cover them with a thin layer of soil. Keep soil moist but not waterlogged and in the sun or partial shade. The seeds will usually germinate within 2 to 3 weeks.
Division Propagation
Achillea Ligustica All. can also be propagated through division. This method is usually done in the early spring or fall. Divide the plant by carefully digging up the whole plant and gently loosening the soil around its roots. Separate the plant into smaller sections, ensuring that each section contains root and shoots. Replant immediately into a well-prepared soil and maintain consistent moisture while establishing.
Cutting Propagation
Achillea Ligustica All. can also be propagated through cutting propagation. This method is relatively simple and involves taking stem cuttings during the summer. Cut a few stems from a healthy plant and remove the bottom leaves and flowers. Dip the cuttings in hormone rooting powder and plant them into a well-draining soil in a warm and bright spot. Keep soil moist and a high humidity until a strong root system has developed. Once new growth appears, transplant the rooted cuttings into a well-prepared soil.
In conclusion, Achillea Ligustica All. can be propagated through different methods such as seed, division, and cutting propagation. The chosen propagation method depends on personal preference and the available resources.
