Light Requirements
Marasmodes polycephala DC. var. oligocephala (DC.) Harv. requires full sun to grow and flourish. It cannot tolerate shade or partial shade.
Temperature Requirements
The plant requires a moderate temperature range to grow. It thrives in temperatures between 18°C to 25°C. During the winter season, the temperature should not drop below 10°C.
Soil Requirements
The plant grows best in well-draining soil. It does not tolerate waterlogged soil or soil with poor drainage. The soil should be slightly acidic to neutral, with a pH range of 6.0 to 7.5.
The plant is adapted to grow in sandy or gravelly soil. In areas with clay soil, it is recommended to add sand or gravel to aid in drainage. The plant also benefits from the addition of organic matter to the soil.
Cultivation methods
The Marasmodes polycephala DC. var. oligocephala (DC.) Harv. plant can be grown in different ways, including pot cultivation, planting in a garden, and propagation through cuttings. Pot cultivation is ideal for those who don't have a garden space since it can be grown indoors. On the other hand, planting in a garden requires a sunny position with well-draining soil. Propagation through cuttings should be done during the spring season.
Watering needs
The watering needs of Marasmodes polycephala DC. var. oligocephala (DC.) Harv. are moderate, requiring adequate watering to keep the soil moist but not waterlogged. During the summer months, you may need to water the plant frequently, preferably every day, since the increased temperatures tend to dry the soil faster. During the winter months, you might need to reduce the watering frequency to once every two weeks, depending on how fast the soil dries up.
Fertilization
Fertilization is necessary to promote the growth and the health of Marasmodes polycephala DC. var. oligocephala (DC.) Harv. plant. It would be best to use fertilizers rich in potassium, nitrogen, and phosphorus during the growing season, which is between the spring and summer months. This ensures that the plant has the necessary nutrients to produce healthy leaves and promote flowering. It is advisable to avoid fertilizing the plant in winter since its growth rate decreases, and feeding can lead to the accumulation of salt in the soil.
Pruning
Marasmodes polycephala DC. var. oligocephala (DC.) Harv. is prone to becoming leggy, so regular pruning is vital to control its size and shape. It is best to do the pruning before the flowering season to promote the production of new buds and, therefore, an abundant blooming the following season. While pruning, it is advisable to use sharp, clean shears to avoid damage to the plant.
Propagation of Marasmodes polycephala DC. var. oligocephala (DC.) Harv.
Marasmodes polycephala DC. var. oligocephala (DC.) Harv. can be propagated through three methods, namely:
1. Seed propagation
The seed propagation method involves sowing the seeds in a well-draining soil mix. The seeds should be sown at a depth of about 2-3 mm and then covered lightly with soil. Proper moisture should be maintained, and the soil should be kept moist but not waterlogged. The seeds usually germinate within 2-4 weeks.
2. Cutting propagation
The cutting propagation method involves taking stem cuttings from a healthy and mature plant of Marasmodes polycephala. The cuttings should be taken in early spring or late summer when the plant is actively growing. The cuttings should be about 10-15 cm long and should be taken from the tip of a stem. The lower leaves should be removed, and the cutting should be dipped in rooting hormone before being inserted into a well-draining soil mix. Proper moisture should be maintained, and the soil should be kept moist but not waterlogged. The cutting usually roots within 4-6 weeks.
3. Division propagation
The division propagation method involves dividing the root ball of a mature Marasmodes polycephala plant into smaller sections. The plant should be dug out carefully, and the root ball should be divided into several sections using a sharp and sterilized tool. Each section should have a well-developed root system and a few stems and leaves. The divided sections should be planted in well-draining soil mix, and proper moisture should be maintained. The plant usually establishes within a few weeks.
Management of Diseases and Pests in Marasmodes polycephala DC. var. oligocephala (DC.) Harv.
Marasmodes polycephala DC. var. oligocephala (DC.) Harv. is commonly known as small-headed Marasmodes, and it is a South African evergreen shrub that belongs to the asteraceae family.

Another disease that affects the Marasmodes polycephala DC. var. oligocephala (DC.) Harv. is root rot. Root rot is caused by waterlogged soil, which can lead to rhizome rot and stem rot. To manage this disease, always ensure that the soil is well-draining, and try to avoid overwatering the plant. You can also apply fungicides to control root rot.
Pests
One of the common pests that might attack the Marasmodes polycephala DC. var. oligocephala (DC.) Harv. is aphids. Aphids are small insects that suck sap from the plant, which can lead to stunted growth and yellowing of the leaves. To manage aphids, you can spray the plant with insecticidal soap or neem oil.
Another pest that might attack the Marasmodes polycephala DC. var. oligocephala (DC.) Harv. is the thrips. Thrips are tiny insects that feed on the leaves, causing them to curl and turn brown. To manage thrips, you can apply insecticidal soap or neem oil. You can also remove and discard the affected leaves.
In conclusion, the Marasmodes polycephala DC. var. oligocephala (DC.) Harv. is prone to both diseases and pests. Therefore, it is essential to maintain a regular inspection of the plant and practice good cultural practices, such as proper watering, nutrition and air circulation, to help keep the plant healthy and prevent infestation.
