In areas with warm climates, it is best to grow the plant in a location that receives shade during the hottest part of the day.
Soil Requirements
Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl. prefers well-draining soils with a pH between 6.0-7.5. It can tolerate a wide range of soil types but grows best in loamy soils with good drainage. The plant is well adapted to growing in rocky soils and can grow in soils with low fertility.
It is important to avoid waterlogging the soil as it can lead to root rot and other fungal diseases. The plant is also tolerant of drought conditions but may require more frequent watering during dry periods.
Cultivation
Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl. commonly known as African wormwood is an indigenous shrub widely cultivated in Ethiopia. It grows well in a dry and warm environment. The plant prefers a sandy-loam soil type that is well-drained and has a pH of 6.5-7.5. It can be propagated through seeds or cuttings.
Watering Needs
African wormwood requires moderate watering, especially during the growing season. It is important to avoid over-watering as this may lead to root rot. The soil should be allowed to dry before the next watering session. It is important to note that the plant is drought-tolerant and thus can withstand long periods of dry spells.
Fertilization
African wormwood is a hardy plant that does not require heavy fertilization. However, to boost growth and plant health, it is recommended to apply a balanced fertilizer during the growing season. The fertilizer should be applied sparingly as too much may result in excessive foliage growth and poor flower development.
Pruning
Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl. rarely requires pruning. However, to maintain its shape and size, it is recommended to prune the plant immediately after flowering. This will also encourage more flower development.
Propagation of Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl.
Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl. can be propagated through both seed and vegetative methods.
Propagation through seed
The plant produces small, dry, and light seeds that can be harvested from the seed heads after they have turned brown. The seeds should be sown in a seedbed in early spring at a depth of no more than 2 mm. The soil should be kept moist during germination, which usually occurs within 7-10 days. Seedlings should be transplanted into the field after 4-6 weeks.
Propagation through vegetative methods
The plant can also be propagated through vegetative methods like cuttings and division. Cuttings should be taken in early spring from young stems and should be approximately 10-15 cm long. The lower leaves should be removed, and the cutting should be planted in a rooting medium and kept under high humidity until root formation occurs, after which they can be transplanted into the field.
Division can be carried out by lifting and dividing the plant's root system into smaller sections. This method is best done during the plant's dormant period, which is in late fall or early spring.
Disease Management
Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl. is susceptible to fungal, bacterial and viral diseases.
Common diseases include:
- Leaf spot: This disease is characterized by the appearance of brown or black spots on the leaves. To manage this disease, remove and destroy all infected plant parts and maintain good garden hygiene by removing all plant debris from the garden.
- Powdery mildew: This fungal disease affects the foliage, causing the formation of a white, powdery coating. To manage powdery mildew, remove infected plant parts and spray with a fungicide. Additionally, ensure that the plants are not overcrowded and have good airflow to reduce the humidity levels in the garden.
- Verticillium wilt: This fungal disease causes the plant to wilt and die. It is difficult to manage, and the best way to prevent it is to grow disease-resistant cultivars and maintain good garden hygiene.
Pest Management
Artemisia abyssinica Sch.Bip. ex A.Rich. var. eriocephala Sch.Bip. ex Engl. is relatively resistant to pests. However, you might still encounter some pests that can damage the plant. Common pests include:

- Spider mites: These tiny arachnids feed on the sap of the leaves, causing them to turn yellow and dry out. They can be managed by spraying the plant with a miticide or insecticidal soap.
- Leaf miners: These insects feed on the foliage, causing the formation of tunnels in the leaves. They can be managed by removing the affected leaves and spraying the plant with an insecticide.
