Artemisia globularia Cham. ex Bess. is a hardy perennial plant and is relatively easy to grow if provided with the right growing conditions. It is a sun-loving plant and should be planted in a spot that receives at least six hours of sunlight daily.
The soil should be well-draining and fertile. It is best to plant the Artemisia globularia Cham. ex Bess. in sandy or loamy soil that is slightly alkaline. Adding organic matter, such as compost or aged manure, to the soil is also beneficial for growth.
The ideal time to plant the Artemisia globularia Cham. ex Bess. is in the spring after the threat of frost has passed. Plant the seedlings or cuttings at a depth of about 1 to 2 inches and space them apart by around 18 inches.
Watering Needs of Artemisia globularia Cham. ex Bess.
Artemisia globularia Cham. ex Bess. is a drought-tolerant plant and does not require frequent watering. Overwatering can cause root rot, so it is vital to let the soil dry out between watering sessions.
Water the plant deeply when the soil has become dry to a depth of around one inch. Watering once every two weeks is usually sufficient, but this may vary depending on the climate and soil conditions.
Fertilization of Artemisia globularia Cham. ex Bess.

It is best to fertilize the plant during the growing season, ideally in the spring and fall when the plant is actively growing. Avoid fertilizing in the winter when the plant is dormant.
Pruning of Artemisia globularia Cham. ex Bess.
Pruning Artemisia globularia Cham. ex Bess. is not strictly required but can lead to a bushier plant with an abundance of foliage. You can cut back the plant by around a third in the late summer after flowering to encourage new growth and maintain the plant's shape.
Regularly removing any dead or damaged stems or leaves is also advisable to keep the plant healthy.
Propagation Methods for Artemisia globularia Cham. ex Bess.
Artemisia globularia Cham. ex Bess., also known as sand sagebrush, is a popular ornamental plant known for its aromatic properties. Propagation of this plant can be done through various methods such as seeds, cuttings, and division.
Seed Propagation
Seed propagation is the most common and easiest way of propagating Artemisia globularia. The seeds can be sowed directly in the ground or in pots filled with soil in early spring. Before sowing the seed, stratification may be needed for 4 weeks at a temperature between 3 to 5 °C to break the seed dormancy. The seeds should be sowed at a depth of 1 to 2 mm and kept moist until germination. Germination takes about 14 to 30 days.
Cutting Propagation
Cutting is another method of propagating Artemisia globularia. Cuttings should be taken from young stems in early summer when the plant is actively growing. The cuttings should be about 10 to 15 cm long, and the leaves should be removed from the bottom 2 cm of the stem. The cuttings should be dipped in rooting hormone and then stuck in a potting mix consisting of equal parts sand and peat. Cover the pot with a plastic bag to retain moisture and place it in a bright, warm location. Cuttings should root within 3 to 4 weeks.
Division Propagation
Division is the last method of propagating Artemisia globularia and involves dividing the plant's root and stem. Plants should be lifted in spring or early fall when the plant is dormant to avoid damage. The clump should be divided into smaller pieces with a sharp knife and planted in the ground or pots filled with soil. The plants should be kept moist and well-drained, and under partial shade until the plants are established.
Disease and Pest Management for Artemisia globularia Cham. ex Bess.
Artemisia globularia Cham. ex Bess. is generally resistant to pests and diseases. However, certain environmental conditions or insect attacks may cause damage to the plant.
Common Pests
Aphids: Aphids are small, soft-bodied insects that suck the sap from the leaves of the plant, causing them to wilt and turn yellow. They also secrete a sticky substance known as honeydew, which attracts ants and promotes the growth of black sooty mold. Aphids can be controlled by spraying the plant with insecticidal soap or neem oil. Alternatively, beneficial insects such as ladybugs or lacewings can be introduced to the garden to feed on the aphids.
Spider mites: Spider mites are tiny, spider-like creatures that feed on the sap of the plant. They cause the leaves to become stippled and discolored and may produce fine webs over the plant. Spider mites can be controlled by regular spraying of the plant with water to increase the humidity or by introducing predatory mites to feed on them.
Common Diseases
Rust: Rust is a fungal disease that produces orange or yellow-brown pustules on the underside of leaves. It spreads through spores and can lead to defoliation. Rust can be controlled by removing affected leaves and spraying the plant with a fungicide.
Powdery mildew: Powdery mildew is a fungal disease that produces a powdery white substance on the leaves of the plant. It thrives in warm, humid conditions and can be controlled by growing the plant in a location with good air circulation or by spraying it with a fungicide.
Verticillium wilt: Verticillium wilt is a soil-borne fungal disease that causes the leaves of the plant to yellow and wilt. It eventually leads to the death of the plant. Verticillium wilt can be prevented by planting the Artemisia globularia Cham. ex Bess. in well-draining soil and avoiding overwatering.
In conclusion, Artemisia globularia Cham. ex Bess. is a low-maintenance plant that is generally resistant to pests and diseases. However, it is important to monitor the plant for any signs of damage and take appropriate measures to manage pests and diseases when they do occur.
