Light
The plant requires full sun to grow properly. It can tolerate a little bit of shade, but too much shade will cause it to become leggy and weak. It should be planted in a location that receives at least six hours of direct sunlight per day.
Temperature
Pluchea leubnitziae (Kuntze) N.E.Br. is a tropical plant that prefers warm temperatures. It can tolerate temperatures as low as 10°C, but its optimal growth temperature range is between 20°C and 35°C. Extreme cold or heat can damage the plant, so it is best to protect it from frost and provide ample ventilation during hot summer months.
Soil Requirements
The plant grows best in well-drained soils that are rich in organic matter. It is tolerant of a wide range of soil types, including clay, loam, sand, and regular garden soil. However, it needs a soil pH range of 6.0 to 7.5 for optimal growth. In saline areas, it can tolerate a high soil salinity level of up to 10,000 ppm.
Cultivation
Pluchea leubnitziae (Kuntze) N.E.Br. is a plant that is native to the eastern coast of South Africa and can be a great addition to any garden or landscaping design. It can be cultivated in a variety of soils, including sandy, loamy, or clay soils, as long as it has good drainage. The plant prefers full sun but can tolerate partial shade.
Watering Needs
When it comes to watering, Pluchea leubnitziae (Kuntze) N.E.Br. should be watered regularly but should avoid overwatering. A great way to check if the plant needs watering is by sticking your finger into the soil about an inch deep. If the soil feels dry, then it is time to water. If the soil is still moist, then leave it for a few more days before checking again.
Fertilization
Pluchea leubnitziae (Kuntze) N.E.Br. benefits from regular fertilization, especially during the growing season. A balanced liquid fertilizer can be applied every two to three weeks to help promote growth. Alternatively, you can use slow-release fertilizers during the spring and summer months.
Pruning
Pruning of Pluchea leubnitziae (Kuntze) N.E.Br. is relatively low maintenance. It is recommended to remove any dead or damaged branches or flowers as soon as they appear.

Propagation of Pluchea leubnitziae (Kuntze) N.E.Br.
Pluchea leubnitziae (Kuntze) N.E.Br. can be propagated through various methods including:
Seed Propagation
Seeds of Pluchea leubnitziae are generally collected during the flowering season. Seeds should be collected when they start to turn brown and should be sown in a well-drained potting mix. The pot should be kept moist but not overwatered. Seeds generally germinate within 14 to 21 days. Once the seedlings have developed true leaves they can be transplanted into individual pots.
Cuttings Propagation
Pluchea leubnitziae can also be propagated through stem cuttings. Cuttings should be taken from the parent plant using pruning shears and should be at least 5-6 inches long with two or three nodes. Cuttings should be treated with a rooting hormone and planted in a well-draining soil mix. The cuttings should be watered regularly but not overwatered. Roots will generally start to develop within 4 to 6 weeks.
Division Propagation
Pluchea leubnitziae can also be propagated through division. This method is best done in the spring when the plant begins to produce new growth. The parent plant should be carefully removed from the soil and the root system examined. The root system should be divided into smaller sections with a sharp, clean knife. Each section should have some leaves and a small portion of the root system. The new plants can then be transplanted into pots or directly into the garden.
Overall, Pluchea leubnitziae (Kuntze) N.E.Br. is a relatively easy plant to propagate by seed, cuttings or division.
Disease management
Pluchea leubnitziae is generally a disease-resistant plant. However, it may be susceptible to fungal infections such as leaf spot and powdery mildew. These infections can be managed through cultural practices and fungicide application.
