Caralluma longecornuta requires bright light conditions to grow to its fullest potential. This succulent plant can tolerate direct sunlight but does best in partial shade. It is important to protect the plant from extended periods of direct sunlight during the hottest part of the day.
Temperature Requirements
The plant prefers warm temperatures and requires a minimum of 40 degrees Fahrenheit. The optimal temperature range for growth is between 60 and 85 degrees Fahrenheit. It is essential to provide the plant with a warm environment as low temperatures can stunt growth, cause wilting or even kill the plant.
Soil Requirements
The plant prefers well-draining soil, sandy or rocky soils are ideal. Avoid overwatering, as it can cause root rot. A well-mixed soil blend, consisting of sand, gravel, clay, and organic matter, provides the best growing medium. It is important to monitor the level of moisture in the soil and not let the plant dry out for too long.
Cultivation Methods for Caralluma Longecornuta Croizat ex Gomes e Sousa
Caralluma longecornuta Croizat ex Gomes e Sousa can be grown in sandy, loamy or clay-rich soil. It can tolerate a wide range of soils as long as it is well-drained. Ensure that the plants get sufficient sunlight, preferably in a spot that receives 4-6 hours of direct sunlight daily.
If you reside in areas where there are heavy rains, make sure that there is a proper drainage system to ensure the plants are not waterlogged for long durations.
Watering Needs
The watering frequency differs based on the area's climate and soil type. During summer, the plant needs to be watered regularly, maybe twice a week. Keep the soil moist but not waterlogged. During winter, reduce the frequency of watering to prevent the plant from becoming waterlogged.
Fertilization
Using a balanced fertilizer, you can promote plant growth by adding nutrients that may be lacking in your soil. During the planting process, add organic fertilizer around, or you can use a slow-acting granular fertilizer. If the soil in your garden lacks essential nutrients, regular feeding with liquid fertilizer can be helpful.
The fertilizers' composition should have a balanced nitrogen, phosphorus, and potassium ratio. For plants grown in a container, dilute the fertilizer to half the recommended strength to prevent over-fertilization.
Pruning
Pruning the plant is essential to encourage branching and improve its shape. You should prune Caralluma longecornuta Croizat ex Gomes e Sousa often, primarily if it becomes leggy or too tall. Cut off the top 4-6 inches of stems with sharp shears, pruning the stem just above where the leaves meet the stem key.
Removing dead, diseased, or damaged leaves will help keep the plant healthy. To achieve the best results, sterilize your pruning shears to prevent spreading diseases from infected plants to healthy ones.
Propagation of Caralluma longecornuta Croizat ex Gomes e Sousa
Caralluma longecornuta Croizat ex Gomes e Sousa is usually propagated by seed or stem cuttings.

Propagation by Stem Cuttings
Stem cuttings are usually taken during the growing season. A stem cutting should be around 10-15 cm in length and should be taken from a healthy plant. Remove the leaves from the bottom half of the cutting and allow the stem to dry for a few hours. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. The pot should be placed in a warm and bright location, but out of direct sunlight. The soil should be kept moist but not waterlogged.
