Specific potting mixes that contain equal parts of perlite, sand, and loam are useful for growing Conophytum odoratum in containers. It is also advisable to shallowly plant them so that only a small part of the plant is visible above the soil surface. Good drainage is essential for preventing rotting and waterlogging of the roots, which is detrimental to their growth.
Cultivation Methods:
Conophytum odoratum (N.E.Br.) N.E.Br. is a small succulent plant. As such, it is essential to cultivate it in a suitable environment. It is best to plant it in well-draining soil that is rich in nutrients. The use of a plastic pot with drainage holes is highly recommended for better drainage. In general, Conophytum odoratum (N.E.Br.) N.E.Br. is best planted in late summer to early fall. This way, it will establish itself and be ready to bloom when the growing season begins.
Watering Needs:
Conophytum odoratum (N.E.Br.) N.E.Br. is a succulent, which means that it does not require a lot of watering to thrive. In fact, overwatering can be detrimental to the plant. The best way to water Conophytum odoratum (N.E.Br.) N.E.Br. is to allow the soil to dry out completely between watering sessions.

Propagation of Conophytum odoratum
Conophytum odoratum (N.E.Br.) N.E.Br. can be propagated through different methods:
Seed propagation
Seeds of Conophytum odoratum can be sown in a well-draining mix, containing sandy soil, peat, perlite, and/or pumice. The seeds need to be barely covered with the mix, as they require light for germination. Depending on the temperature and humidity, the seeds can take several weeks to months to germinate. The seedlings need to be watered sparingly, as they are prone to rot. When the seedlings have grown several pairs of leaves, they can be transplanted into individual pots or a communal tray, depending on the grower's preference.
Leaf propagation
Conophytum odoratum can also be propagated through leaf cuttings. The leaves of established plants can be carefully removed and placed on a well-draining mix. After a few days, small roots will start to emerge from the base of the leaves. The leaf cuttings can be watered sparingly, as they are prone to rot. Once the cuttings have established roots and started to grow new leaves, they can be transplanted into individual pots or a communal tray, depending on the grower's preference.
Division
Conophytum odoratum can be divided by carefully removing offsets from the mother plant. The offsets should have a few pairs of leaves and be intact, without any damage to the roots. The offsets can be planted in a well-draining mix and watered sparingly until they have established roots and started to grow new leaves. Once the offsets have started to grow, they can be transplanted into individual pots or a communal tray, depending on the grower's preference.
Disease and Pest Management for Conophytum Odoratum
Conophytum odoratum is generally a disease-resistant plant.

Diseases
1. Fungal infections: Fungal infections are one of the most common problems in Conophytum odoratum. These infections usually occur due to over-watering, high humidity, and poor airflow. Symptoms of fungal infections include wilting, brown spots on the plant, and rotting of roots. To manage this issue, avoid over-watering, ensure proper ventilation, and promptly remove any dead or infected plant material. Also, use a fungicide to prevent the disease from spreading.
2. Bacterial infections: Bacterial infections can also occur due to poor ventilation, over-watering, and inadequate light conditions. Symptoms of bacterial infections include yellowish or brownish spots on the leaves and stems. It may also lead to wilting and dying of the plant. To manage this issue, remove the affected parts of the plant immediately, improve ventilation, avoid over-watering, and provide sufficient sunlight.
Pests
1. Spider mites: Spider mites are a common pest that can affect Conophytum odoratum, especially in hot and dry conditions. These pests cause yellowing and curling of the leaves, and their fine webbing may also be visible on the plant. To manage this issue, regularly spray the plant with water to increase humidity and remove spider mites physically. Also, use an insecticidal soap or neem oil to control their population.
2. Mealybugs: Mealybugs are another common pest that damages the plant. These pests cause yellowing of leaves and stunted growth. They also produce a white, powdery substance, which can be seen on the plant and pot. To manage this issue, physically remove them from the plant, and use a neem oil solution for effective control.
Regular monitoring of Conophytum odoratum for diseases and pests, maintaining appropriate light, temperature, and moisture level, and prompt action to control the issues are essential for the growth and survival of the plant.
