Light Requirements
Calesiam somalensis Chiov. is a plant that requires full sunlight to grow to its full potential. The plant should be placed in areas where it can absorb maximum light during the day. Exposure to partial shade or dim light can impact its growth adversely.
Temperature Requirements
The plant can grow in a broad range of temperatures typical of arid and semi-arid environments. Calesiam somalensis Chiov. can survive low temperatures of -4°C and high temperatures of up to 38°C. However, its optimal growth conditions lie between 15°C and 35°C. Growers should avoid exposing the plant to temperature extremes as it may impact its growth, damage leaves and roots, and affect its overall health.
Soil Requirements
Calesiam somalensis Chiov. grows well in well-draining soils that are rich in nutrients. The plant prefers sandy or loamy soils with a pH range between 6.0 and 7.8. Sandy soils help to improve drainage while loamy soils retain moisture and nutrients, keeping the plant hydrated. The soil should be lightly fertilized to promote plant growth. Over-fertilizing should be avoided as it can damage the plant.
Watering Requirements
The plant is drought-tolerant and can survive with less water. However, for optimal growth, it requires regular watering, especially during the flowering period. The plant should be watered at least twice a week in moderate amounts. Over-watering should be avoided as it can lead to root rot and damage the health of the plant.
Cultivation of Calesiam somalensis Chiov.
Plant Calesiam somalensis Chiov. in well-drained soil that is rich in organic matter. The plant prefers full sun but can tolerate partial shade. The ideal planting time is during the rainy season when the soil is moist. Dig a hole that is slightly larger than the plant's root ball, and plant the root ball at the same level as the soil surface. Water the plant immediately after planting.
Watering Needs
Calesiam somalensis Chiov. requires regular watering to thrive. Water the plant deeply once a week during the dry season, and reduce watering frequency during the rainy season. The soil should be evenly moist but not waterlogged. Avoid wetting the foliage as it can cause fungal diseases.
Fertilization
The plant benefits from regular fertilization to promote healthy growth and blooming. Apply a balanced fertilizer or a slow-release fertilizer every two months during the growing season. Follow the recommended dosage on the fertilizer label, and apply the fertilizer evenly around the base of the plant. Water the plant after fertilizing to help the nutrients reach the roots.
Pruning
Calesiam somalensis Chiov. can be pruned to promote bushier growth and maintain a desirable shape. Prune the plant during the dormant season, or after blooming. Use clean and sharp pruning shears to make clean cuts. Remove any dead, diseased, or damaged branches. Cut back the tips of the branches to encourage branching. Avoid pruning more than one-third of the plant at once.
Propagation of Calesiam somalensis Chiov.
The propagation of Calesiam somalensis Chiov. can be done through both sexual and asexual methods. The method that is commonly used is through seed propagation, which is described below:
Seed propagation
Seeds of Calesiam somalensis Chiov. can be collected from the parent plants during the fall season. The collected seeds must be cleaned of any debris and properly dried in a warm and ventilated area. Once the seeds are thoroughly dried, they can be stored in an airtight container in a cool and dry place until they are ready for propagation.
The seeds of Calesiam somalensis Chiov. require certain conditions for successful germination. The seeds must first be soaked in water for several hours to break their dormancy. After soaking the seeds, they can either be sown directly into the soil or in raised seedbeds filled with a mixture of soil, sand, and compost in equal proportions. The seeds must be covered with a thin layer of soil and kept moist until germination.
Germination usually occurs in 2 to 4 weeks, depending on the temperature and humidity levels. Once the seedlings are large enough to handle, they can be transplanted into bigger pots or directly into the garden. It is important to note that Calesiam somalensis Chiov. requires well-drained soil and adequate water supply for optimal growth.
Asexual propagation
Calesiam somalensis Chiov. can also be propagated through stem cuttings. This method is useful if the parent plant is mature and cannot produce viable seeds. The stem cuttings must be taken during the active growing season and must have at least one node. The cuttings must be planted in a mixture of sand and compost and kept moist. Once the cuttings form roots and new leaves, they can be transplanted into bigger pots or directly into the garden.
Disease Management for Calesiam somalensis Chiov.
The fungal disease powdery mildew can affect Calesiam somalensis Chiov. To manage powdery mildew, prune plant growth to increase air circulation, water at the base of the plant rather than from overhead, and apply fungicide as needed.
Root rot caused by the fungus Phytophthora parasitica can also affect Calesiam somalensis Chiov. To manage root rot, improve soil drainage, avoid overwatering, and remove infected plants to prevent the disease from spreading.
Pest Management for Calesiam somalensis Chiov.
Aphids may attack Calesiam somalensis Chiov. To manage aphids, introduce natural predators like ladybugs, prune infested growth, and spray insecticidal soap as needed.
The small white larvae of leaf-mining flies can also feed on Calesiam somalensis Chiov. To manage leaf-mining flies, remove and dispose of damaged leaves, treat with insecticidal spray, and introduce parasitic wasps that will attack the leaf-mining fly larvae.
