Soil Requirements
The plant prefers well-draining soil, sandy or loamy types, with a pH ranging from 6.0 to 7.5. Cotyledon teretifolia Lam. can tolerate drought conditions, so it does not require frequent watering. However, it is essential to keep the soil slightly moist during the growing season.
Cultivation
Cotyledon teretifolia Lam. thrives in well-drained soil, and it is suitable for both indoor and outdoor cultivation. In outdoor cultivation, it prefers partial shade to full sun exposure. However, in indoor cultivation, it requires bright but indirect light. The plant adapts well to the surrounding temperature, and it can survive extreme temperatures of up to 50°C. Cotyledon teretifolia Lam. requires occasional repotting, mainly during the growing period.
Watering Needs
The plant requires moderate watering, with intervals of at least two weeks during the winter period and weekly intervals during the summer period. During watering, ensure that the soil is entirely soaked. The plant's water needs tend to reduce during its dormancy period. Avoid overwatering the plant since it results in root rot.
Fertilization
Cotyledon teretifolia Lam. does not require frequent fertilization. Use a mild liquid fertilizer once every four to six weeks during the plant's growing phase to encourage a rich foliage growth. However, avoid fertilization during the plant's dormancy period.
Pruning
Pruning the plant encourages bushy growth and enhances its overall appearance. It is advisable to prune the Cotyledon teretifolia Lam. during the growing phase. However, pruning should be minimal, only to remove dead or yellowing leaves. Over-pruning the plant affects its growth and development.
Propagation of Cotyledon Teretifolia Lam.
Cotyledon teretifolia Lam. is a succulent plant that belongs to the family Crassulaceae. It is commonly known as the Pig's Ear Succulent due to the shape of its leaves. This plant is native to the eastern coast of South Africa and is known for its ornamental value. Propagation of Cotyledon teretifolia Lam. can be done through various methods:
Leaf Cuttings Propagation
Cotyledon teretifolia Lam. can be propagated easily through leaf cuttings. Choose a healthy leaf and remove it gently from the mother plant.

Disease and Pest Management for Cotyledon teretifolia Lam.
Cotyledon teretifolia Lam. is a succulent plant species that belongs to the family Crassulaceae. This plant is usually low maintenance, but it can still be prone to various pests and diseases. Here are some common diseases and pests that might affect Cotyledon teretifolia Lam. and some ways to manage them.
Common Diseases
1. Powdery Mildew: This is a fungal disease that appears as a white powdery coating on the plant's leaves. It can cause the leaves to become distorted and yellow, eventually leading to their death.
Management: To manage powdery mildew, firstly, remove infected plants or plant parts. Avoid overhead watering which can create a favorable environment for the growth of the fungus. Fungicides can be used to manage severe cases of the disease.
2. Root Rot: Root rot is a fungal disease that usually happens when the soil is kept constantly wet, leading to the roots rotting and withering away.
Management: To manage root rot, always avoid overwatering the plant, ensure that the plant is grown in well-draining soil. Remove affected plants or plant parts, and ensure that the remaining plants are not placed too close to each other, allowing proper ventilation and the prevention of spread of the disease.
Common Pests
1. Mealybugs: These are small, soft-bodied insects with a white cotton-like appearance. They usually attack the leaves, stems, and roots of the plant while sucking the sap; this can cause stunted growth and yellowing of the leaves.
Management: To manage mealybugs, use natural predators, such as ladybugs or green lacewings. You can also use a cotton swab dipped in rubbing alcohol to rub off the insects, or use insecticides that have systemic properties.
2. Spider Mites: These are tiny, eight-legged pests that usually attack the undersides of leaves, causing the leaves to yellow and eventually fall off. They reproduce very quickly and can lead to a severe infestation in a short period.
Management: To manage spider mites, spray the plant with water regularly to keep the leaves clean and free of dust, which can create a favorable environment for the growth of the mites. You can also use neem oil or insecticidal soap for effective control.
By being vigilant and monitoring your Cotyledon teretifolia Lam. plant regularly, you can identify the signs of diseases and pests early and take the necessary steps to manage them effectively.
