Soil Requirements
Arctotis verbascifolia Harv. prefers a well-draining soil with a pH range of 6.0-7.0. The soil should be rich in organic matter and mixed with sand or perlite to improve drainage. Water the plant when the top inch of the soil dries out, and avoid over-watering as it can cause root rot. Fertilize the plant with a balanced fertilizer every two weeks during the growing season to promote healthy growth and flowering.
Cultivation Methods
Arctotis verbascifolia Harv. is a low-growing, perennial shrub that thrives in full sun and well-draining soil. The plant can tolerate average soil conditions, but it prefers soil that is rich in organic matter with a pH range of 6.0 to 7.0. You can grow Arctotis verbascifolia Harv. in containers or as a border plant. To have the best cultivation results, sow seeds or cutting in spring or early summer.
Watering Needs
Arctotis verbascifolia Harv. is drought tolerant and can survive in dry soil conditions if provided with light watering. It is essential to avoid overwatering, as it can cause root rot. Water your plant when the soil dries out, and ensure that the water penetrates deep into the soil to encourage root growth. Avoid watering the foliage to prevent the development of fungal diseases.
Fertilization
Arctotis verbascifolia Harv. requires fertilization once every two weeks during the growing season. Use a balanced liquid fertilizer, and ensure that it contains all the essential nutrients for proper plant growth and development. Fertilize the plant early in the morning or late in the evening to prevent leaf scorching and root damage.
Pruning
Pruning is essential for maintaining the shape and size of Arctotis verbascifolia Harv. It is best to prune the plant during late winter or early spring to encourage the growth of new stems and flowers. Use a sharp pair of pruning shears, and remove any dead, diseased, or damaged stems. Always cut back to healthy growth. Lightly prune the plant after the summer flowering season to encourage a more compact growth habit and to remove any spent flowers.

Common diseases
The most common diseases that affect Arctotis Verbascifolia Harv. include fungal diseases, powdery mildew, and root rot.
Fungal diseases
Fungal diseases are the most common disease in indoor plants. The symptoms of fungal diseases include leaf yellowing, tissue necrosis, and plant wilting.

Use a fungicide to stop the spread of disease.
Powdery Mildew
Powdery mildew is a fungal disease that is characterized by a white powdery substance on leaves and stems. This disease is caused by growing the plant in poorly ventilated areas. As a prevention method, ensure that plants are placed in well-ventilated areas and maintain proper air circulation. Infected plants can be treated with a fungicide that can be applied directly to the leaves and stem.
Root Rot
Root rot is often caused by overwatering the plant causing the roots to rot. Symptoms of root rot are slow growth, yellowing of leaves, and droopy leaves. The best way to manage root rot is to reduce watering, and apply a fungicide to the affected zones.
Common Pests
The most common pests that affect Arctotis Verbascifolia Harv. are spider mites, mealybugs, and aphids.
Spider Mites
Spider mites are often found in indoor plants. Symptoms of spider mites are the presence of webbing around leaves and yellow spots on the leaves. To manage spider mites, use organic sprays or insecticidal soap to control the mites and their eggs.
Mealybugs
Mealybugs are small, white, cotton-like pests that appear in the leaf axils, leaf veins, and stem crevices. Overpopulation by mealybugs weakens the plant and causes it to decline. You can get rid of mealybugs by washing the plant with water and then use alcohol or insecticidal soap to eliminate them completely.
Aphids
Aphids damage plants by sucking the sap from leaves which causes them to curl and wilt. Symptoms of aphids are the presence of sticky residue and clusters of small, soft-bodied insects. To manage aphids, use insecticidal soap or neem oil spray with proper ventilation.
