This plant prefers cool to cold temperatures, and most of its natural growth occurs in areas with cold winters. It can tolerate temperatures as low as -10°C and can grow in USDA hardiness zones 6 to 9. During the summer months, the plant can withstand temperatures of up to 30°C, but should not be exposed to prolonged heat exposure.
Soil Requirements:
Nivenia levynsiae grows best in well-draining, sandy soils, rich in organic matter. It can tolerate slightly acidic to alkaline soils, with pH levels ranging from 6.0 to 8.0. The soil should also be moist, but not waterlogged, as this can lead to root rot which is detrimental to its growth. When planting, adding compost or organic matter to the soil helps in providing additional nutrients to the plant.
Cultivation
Nivenia levynsiae Weim. is a South African succulent plant that requires well-draining soil and a warm environment to grow. It can be cultivated both indoors and outdoors, provided that the growing conditions are carefully regulated. The plant needs to be exposed to full sunlight for at least six hours a day, and it should be placed in a location that is sheltered from strong winds and heavy rainfall. If the temperature drops below freezing, it is recommended to keep the plant indoors.
Watering Needs

Aphids are small, pear-shaped insects that suck sap from the plant, causing deformities and stunted growth.
Disease Management
In the case of fungal diseases, it is essential to maintain proper hygiene and airflow around the plant to reduce humidity. Avoid overwatering and use well-draining soil. If powdery mildew and leaf spot occur, remove and dispose of infected leaves immediately. A fungicide treatment may also be necessary in severe cases.
Pest Management
To manage insect pests on Nivenia levynsiae Weim., use neem oil or insecticidal soap. These products are safe and effective against most common pests.
