Harv. requires a soil that is rich in nutrients, particularly nitrogen and phosphorus, to promote healthy growth and development.
Cultivation Methods
Athanasia trifurcata (L.) L. var. glabra (Thunb.) Harv. should be grown in well-draining soil with a pH level ranging from 5.5 to 7.5. It is essential to plant this perennial in an area with full exposure to the sun, as it thrives well in direct sunlight. It is advisable to sow the seeds during spring and summer or transplant them during the same period for faster growth. The plant can grow up to 60 cm in height and requires enough space to form a shrub-like shape.
Watering Needs
Athanasia trifurcata (L.) L. var. glabra (Thunb.) Harv. requires an adequate water supply for optimal growth. It is recommended to provide water regularly depending on the weather condition. During hot, arid seasons, the plant needs frequent watering to avoid withering. It is, however, advisable to avoid over-watering the plant as it is sensitive to root rotting.
Fertilization
It is advisable to provide Athanasia trifurcata (L.) L. var. glabra (Thunb.) Harv. with sufficient nutrients through application of fertilizer during the growing season. It is advised to use a balanced fertilizer formula with an N-P-K ratio of 10-10-10. It is essential to follow the manufacturer's instructions on the use, dosage, and frequency of fertilization for the best results.
Pruning
Pruning Athanasia trifurcata (L.) L. var. glabra (Thunb.) Harv. involves removing dead or wilted leaves, flowers, and the excess growth of stems using pruning shears.

Propagation of Athanasia trifurcata var. glabra
Athanasia trifurcata var. glabra, also known as "Bushman's Tea," is a hardy and drought-tolerant plant native to South Africa. Propagation of this plant can be done in several ways, including:
Seed Propagation
The easiest way to propagate Athanasia trifurcata var. glabra is through seed propagation. Mature seeds can be collected from dry flower heads and planted directly into well-draining soil. The seeds should be planted shallowly, covered with a light layer of soil, and watered regularly until germination occurs. Germination can take anywhere from one to four weeks, depending on the conditions.
Division
Athanasia trifurcata var. glabra can also be propagated through division. This method is best done in the spring when new growth is beginning to emerge. Simply dig up the plant and carefully divide the root ball into smaller sections, making sure each section has adequate roots and foliage. Replant the sections into well-draining soil and water regularly until new growth appears.
Cuttings
Another propagation method for Athanasia trifurcata var. glabra is through cuttings. Take cuttings from softwood growth in the spring or early summer. Cut a stem 4-6 inches long and remove the lower leaves, leaving only a few at the top. Dip the end of the stem in rooting hormone and plant it in well-draining soil. Keep the soil moist until new growth appears.
Disease and Pest Management for Athanasia trifurcata (L.) L. var. glabra (Thunb.) Harv.
Athanasia trifurcata is a hardy plant that is relatively resistant to pests and diseases. However, to help the plant maintain its health, it is still important to keep watch for potential problems and take appropriate measures to manage them as soon as they appear.
Pests
One of the most common pests to affect Athanasia trifurcata is the aphid. These tiny insects feed on the sap of the plant, which can lead to discoloration and weakening of the foliage. To manage an aphid infestation, you can either blast the plant with a strong stream of water to dislodge the aphids or apply insecticidal soap, following the label directions carefully.
Another potential pest is the spider mite. These creatures are so small they're barely visible to the naked eye, but their damage is quite noticeable. Spider mites suck the sap from the leaves, causing tiny yellow or white dots to appear on the foliage. If left unchecked, an infestation can cause the leaves to turn brown and drop off. To manage spider mites, try washing the leaves with a solution of water and dish soap or use an insecticidal soap product that targets spider mites.
Diseases
Athanasia trifurcata is fairly resistant to fungal diseases, but there is one that can cause problems – powdery mildew. Powdery mildew is a fungal disease that appears as a white, powdery coating on the leaves, stems or flowers of the plant. To manage powdery mildew, remove any infected plant material and try increasing air circulation around the plant. It may also be helpful to apply a fungicide to the plant, following the label directions carefully.
Another potential fungal disease that can affect Athanasia trifurcata is crown rot. This disease attacks the plant's root system, causing the crown of the plant to turn brown and mushy. Unfortunately, there is no cure for crown rot, so prevention is the key. Be sure to plant in well-draining soil, and avoid overwatering the plant.
