In summary, to ensure optimal growth of Artemisia pedatifida Nutt., it is important to provide full sun exposure, maintain warm temperatures during the day and cool temperatures at night, and plant it in well-draining soils with moderate moisture levels and a pH ranging from 6.0-8.0.
Cultivation
Artemisia pedatifida Nutt. is best grown from seeds. The seeds can be directly sown outdoors in the fall or spring. Ensure the soil is well-draining and has full exposure to the sun. The seeds need light to germinate, so avoid covering them with soil.
Watering Needs
Watering requirements for Artemisia pedatifida Nutt. are low once the plant has established itself in the soil. Watering should be done when the soil has completely dried out and not more frequently than once a week.
Fertilization

Pruning
Pruning is not necessary for Artemisia pedatifida Nutt. However, if it becomes too large for the space, it can be pruned back in the early spring before new growth starts. The plant should be pruned to its desired shape and size.
Propagation of Artemisia pedatifida Nutt.
Artemisia pedatifida Nutt., popularly known as palmate-leaved wormwood, is a perennial herbaceous plant commonly found in the western region of North America. It is a drought-tolerant and cold-hardy species that can survive in various soil types. Propagation of this plant can be achieved through several methods:
Seed Propagation
Propagation through seeds is the most common method for Artemisia pedatifida Nutt. Seeds can be collected from mature plants in the fall and stored in a cool, dry place until the following spring. The seeds can then be sown in trays or pots with well-draining soil, covered lightly with soil or vermiculite, and watered regularly. Once the seedlings have grown beyond their first set of true leaves, they can be transplanted to their permanent locations.
Cuttings Propagation
Propagation by cuttings is another method that can be used to multiply Artemisia pedatifida Nutt. Cuttings can be taken in the spring or early summer from new growth that is 4 to 6 inches in length. The cuttings should be planted in a mixture of perlite and peat moss and kept moist until new roots have formed. Once the roots have developed and the plant has grown, it can be transplanted.
Division Propagation
Propagation through division is a method that can be used to create new plants from mature Artemisia pedatifida Nutt. plants. The process involves dividing the root system of a mature plant into smaller sections using a sharp, clean tool. The sections of the root system should have at least one stem and several roots. These sections can be planted in their new location in the spring or fall.
