Light Requirements
Huernia brevirostris var. immaculata requires bright light to thrive. It can tolerate full sun but is best grown in partial shade. When grown in low light conditions, the plant becomes elongated, and the leaves become pale, indicating that it is not receiving enough light.
Temperature Requirements
Huernia brevirostris var. immaculata prefers warm temperatures between 20 - 30°C (68 - 86°F) during the growing season. During the winter months, the plant can tolerate cooler temperatures between 10 - 15°C (50 - 59°F). However, it is essential to protect the plant from frost as it can quickly damage the plant's leaves and stem.
Soil Requirements
Huernia brevirostris var. immaculata requires well-draining soil that is rich in nutrients. A mixture of cactus soil, sand, and perlite is ideal for growing this plant. Avoid using heavy soils that retain moisture as they can cause the plant's roots to rot. Additionally, the plant does not tolerate waterlogging and requires infrequent, deep watering.
Cultivation
Huernia brevirostris N.E.Br. var. immaculata (N.E.Br.) A.C.White & B.Sloane is best grown in well-draining soil mixtures that contain a mixture of perlite, pumice, and sand to promote drainage and prevent waterlogging. The ideal pH range for the soil mix is between 6.0 and 8.0 to ensure that the plant grows well.
The plant should be grown in a location that receives partial to full sunlight, with a minimum of four hours of direct sunlight. It can tolerate temperatures ranging from 50°F to 95°F, but it is recommended to avoid exposing the plant to temperatures below 40°F and above 100°F.
Huernia brevirostris N.E.Br. var. immaculata (N.E.Br.) A.C.White & B.Sloane is susceptible to pests and diseases such as mealybugs, scale insects, and fungal infections. Regularly inspect the plant for any signs of infestation or disease and address them immediately to prevent the spread of pests and diseases.
Watering Needs
The plant prefers to be kept slightly dry, with watering done only once the soil is completely dry. Overwatering can result in root rot, which is fatal to the plant. During the growing season, which is from spring to fall, water the plant once every two weeks. During winter, reduce watering to once every three weeks.
It is recommended to use filtered or distilled water when watering the plant as tap water can contain chemicals and minerals that can harm the plant. Water the plant at the base, avoiding the leaves and stem.
Fertilization
During the growing season, Huernia brevirostris N.E.Br. var. immaculata (N.E.Br.) A.C.White & B.Sloane should be fertilized once every two months, using a balanced fertilizer with a ratio of 10-10-10. Discontinue fertilization during the winter months.
It is essential to follow the manufacturer's instructions when using fertilizers, as over-fertilization can lead to salt build-up in the soil, which can harm the plant's roots.
Pruning
Pruning is not necessary for Huernia brevirostris N.E.Br. var. immaculata (N.E.Br.) A.C.White & B.Sloane. However, it is recommended to remove any dead or yellowing leaves to promote healthy growth. Any dead or damaged stems should be removed using sterile pruning shears to prevent the spread of disease.
Propagation of Huernia brevirostris N.E.Br. var. immaculata (N.E.Br.) A.C.White & B.Sloane
