The plant can tolerate some cooler temperatures, but it should be kept away from extreme heat or cold. During the winter months, the plant should be kept in a cooler room with temperatures ranging from 50°F to 60°F. It is essential to maintain consistent temperature levels to ensure healthy plant growth.
Soil Requirements
Pleiospilos Compactus subsp. Sororius prefers well-draining soil with a neutral to slightly acidic pH. A mixture of 50% coarse sand, 25% perlite and 25% peat moss is ideal for this plant. This type of soil allows for proper drainage and aeration while retaining moisture, which is essential for the succulent plant to store water. Additionally, the plant requires minimal nutrients in the soil, so it is important not to over-fertilize it.
Cultivation
Pleiospilos compactus (Aiton) Schwantes subsp. sororius (N.E.Br.) H.E.K.Hartmann & Liede is a succulent plant that requires proper care and attention. It thrives well in bright sunlight and well-draining soil. The plant needs to be grown in a warm and dry environment, with adequate ventilation.
Propagation through seeds is the primary method, as it grows slowly and takes many years to produce offsets.
Watering Needs
The plant requires minimal watering, as overwatering can lead to root rot. The best approach to watering is to wait for the soil to dry out completely after each watering. The plant can withstand drought for an extended period of time, making it an excellent choice for those who do not have much time to dedicate to plant care.
Fertilization
Pleiospilos compactus (Aiton) Schwantes subsp. sororius (N.E.Br.) H.E.K.Hartmann & Liede requires fertilization once or twice a year. Slow-release fertilizer works best as they provide a constant source of nutrients. Fertilization should be done during the growing season for optimal results.
Pruning
Pruning is not needed for Pleiospilos compactus (Aiton) Schwantes subsp. sororius (N.E.Br.) H.E.K.Hartmann & Liede as it is a slow-growing plant that does not produce many offshoots.

Propagation of Pleiospilos Compactus Subsp. Sororius
Pleiospilos compactus subsp. sororius, also known by the common name "split rock," is a succulent plant native to South Africa. It is a popular houseplant due to its interesting appearance, which resembles a split stone or pebble.
Propagating from Seeds
The most common way to propagate Pleiospilos compactus subsp. sororius is from seeds. The seeds should be sown in well-draining soil mixed with sand to improve drainage. The seeds should be kept moist, but not wet, and should be placed in a warm, bright location that receives indirect sunlight. Germination usually takes between 2-6 weeks.
Propagating from Cuttings
Pleiospilos compactus subsp. sororius can also be propagated from cuttings. Using a sharp, clean tool, cut a piece of stem about 2-3 inches long. Allow the cutting to callus over for a few days, then plant it in well-draining soil mixed with sand. Keep the soil moist but not wet, and place the cutting in a warm, bright location that receives indirect sunlight.
Propagating from Division
An additional method to propagate Pleiospilos compactus subsp. sororius is through division. Gently remove the plant from its pot and separate the plant into smaller sections, ensuring that each section has roots. Replant each section in well-draining soil mixed with sand, and keep it moist but not wet. Place the plant in a warm, bright location that receives indirect sunlight.
Disease and Pest Management for Pleiospilos Compactus (Aiton) Schwantes subsp. Sororius (N.E.Br.) H.E.K.Hartmann & Liede
Pleiospilos compactus (Aiton) Schwantes subsp. sororius (N.E.Br.) H.E.K.Hartmann & Liede, commonly known as the split rock plant, is susceptible to some diseases and pests that can cause damage to the plant. To ensure the health of the plant, it is important to be aware of the common diseases and pests and the ways to manage them.
Common Diseases
The split rock plant can be affected by fungal diseases like leaf spot, root rot, and powdery mildew. These diseases can cause damage to the leaves, flowers, and roots of the plant.
Leaf spot disease is characterized by the appearance of yellow or brown spots on the leaves which eventually lead to their death. To manage this disease, it is recommended to remove the affected leaves and apply a fungicide.
Root rot is caused by overwatering and poor drainage, which leads to the decay of the roots. To prevent the occurrence of this disease, make sure the soil is well-draining and avoid overwatering. In case of infection, it is recommended to remove the affected parts of the plant and start a new plant in fresh soil that is properly drained.
Powdery mildew disease causes a white or gray powdery growth on the leaves and flowers of the plant. To manage this disease, it is recommended to apply a fungicide and ensure proper air circulation around the plant.
Common Pests
Spider mites, mealybugs, and scale insects are common pests that might attack the split rock plant. These pests can cause damage to the leaves, stems, and flowers of the plant.
Spider mites can be identified by the presence of fine webs on the plant and cause discoloration and mottling of the leaves. To manage this pest, it is recommended to remove the affected parts of the plant and apply an insecticidal soap or neem oil spray.
Mealybugs cause a white, cottony appearance on the plant and suck the sap from the plant, leading to stunted growth. To manage this pest, it is recommended to remove the affected parts of the plant and apply an insecticidal soap or alcohol spray.
Scale insects cause a hard, brown shell-like appearance on the plant and suck the sap from the plant, leading to wilting and yellowing of the leaves. To manage this pest, it is recommended to remove the affected parts of the plant and apply an insecticidal soap or neem oil spray.
Regular inspection of the split rock plant and maintaining its optimal growing conditions is essential to prevent disease and pest infestations. Proper watering, fertilization, and sunlight exposure can help the plant resist these infestations and maintain its overall health.
