Light Requirements
Artemisia tacomensis Rydb. generally grows best in areas that receive full sunshine exposure for a minimum of six hours per day. In areas with hot summers, they tend to benefit from partial shade exposure in the afternoon to prevent leaf scorching.
Temperature Requirements
Artemisia tacomensis Rydb. has a strong preference for warmer temperatures and typically grows best in USDA hardiness zones 5 to 9. They can tolerate temperatures as low as -20 degrees Fahrenheit (-28 degrees Celsius) and as high as 100 degrees Fahrenheit (38 degrees Celsius). However, temperatures above 85 degrees Fahrenheit (29 degrees Celsius) may cause stunted growth.
Soil Requirements
The ideal soil type for Artemisia tacomensis Rydb. is well-drained and relatively dry. They prefer a slightly alkaline soil with a pH between 7.0 and 8.0. The plant is also able to grow in nutrient-poor soil, as long as it is well-drained. It is important to note that this plant cannot tolerate wet or poorly-drained soil, as this may lead to root rot or fungal infections.
Cultivation
Artemisia tacomensis Rydb. grows best in full sun and well-drained soil. It is a hardy plant that can tolerate dry conditions, making it suitable for xeriscaping. Placing it in a spot where it is sheltered from strong winds is beneficial for the plant's growth.
Watering Needs
Artemisia tacomensis Rydb. requires moderate watering. Too much water can cause root rot and damage the plant. Water the plant once a week in moderate quantity, or when the soil dries out to an inch deep in the pot. However, the frequency and amount of watering can be influenced by factors such as temperature and humidity of the surrounding.
Fertilization
Although Artemisia tacomensis Rydb. is not a heavy feeder, it may benefit from a little boost of nutrients. Fertilize the plant during the growing season from spring to fall using balanced and water-soluble fertilizers. Be sure to dilute the fertilizer to half-strength to avoid root burn.
Pruning
Pruning Artemisia tacomensis Rydb. involves snipping away dead or damaged leaves. Additionally, pinching off the top of the plant when it reaches about 8-10 inches height can encourage a fuller and bushier growth. Pruning should be done in late winter or early spring before the growing season begins.
Propagation of Artemisia tacomensis Rydb.
Artemisia tacomensis Rydb. is a plant native to North America. It is a perennial shrub that can grow up to 1m tall, with a woody base and greenish-gray leaves.
The plant can be propagated by seeds, cuttings or division.
Seeds

Remove the lower leaves and dip the stem in rooting hormone. Plant the cutting in moist potting soil and cover with plastic to keep the humidity high. Keep the soil moist and in a warm location until roots form.
Division
Division can be done in the spring or fall. Dig up the plant and carefully separate the root ball into smaller sections, making sure each section has both roots and shoots. Replant the individual sections and keep them well-watered until they are established.
