Light Requirements
Clerodendrum cephalanthum Oliv. subsp. cephalanthum prefers to grow in full sun to partial shade. It can tolerate a wide range of light conditions, but it blooms more profusely under higher levels of light.
Temperature Requirements
This plant is native to tropical Africa hence, it prefers warm and humid conditions. The optimal temperature range for its growth is between 18-35°C. It is not frost-tolerant and should be protected from temperatures below 5°C.
Soil Requirements
Clerodendrum cephalanthum Oliv. subsp. cephalanthum grows well in well-draining soils that are rich in organic matter. It can tolerate a range of soil types, including sandy, loamy, or clay soils. The pH of the soil should be between 6.5-7.5.
Cultivation Methods
Clerodendrum cephalanthum Oliv. subsp. cephalanthum is a stunning plant that can be grown both indoors and outdoors. It is best cultivated in well-draining soil with a pH of 6.5 to 7.5. The plant needs ample light, but direct sunlight must be avoided. It thrives in partial to full shade, with temperatures ranging from 18-27°C (65-80°F).
Watering Needs
The plant requires moderate watering. Water should be added when the top soil becomes slightly dry. But be careful not to overwater as it can cause root rot. During the winter months, when the plant is not growing actively, reduce the frequency of watering.
Fertilization
Feed the plant once a month during the growing season with a balanced fertilizer, or a fertilizer that has a higher ratio of phosphorus. This will promote healthy growth and flowering. During the fall and winter months, it is advisable to stop feeding the plant.
Pruning
Pruning should be done after the blooming period, in the fall or winter months. Cut back the plant to promote bushier growth and to manage its size. Pruning must be done with care. Remove any dead or diseased branches and leaves to prevent the spread of disease.
Propagation Methods for Clerodendrum Cephalanthum Oliv. subsp. Cephalanthum
Clerodendrum cephalanthum Oliv. subsp. cephalanthum is commonly known as the "stick-tight" plant and is native to tropical Africa. It is a fast-growing shrub that produces white flowers, which are followed by bright red, fleshy fruits that attract birds. The plant can be propagated through various methods, including:
Seed Propagation
The easiest and most common way to propagate Clerodendrum cephalanthum is by seed. Harvest ripe fruits and remove the pulp, then soak the seeds overnight. Plant them in a seedling tray with a light potting mixture and keep them in a warm and humid area with indirect sunlight. As the seedlings develop, transfer them to individual pots and gradually expose them to direct sunlight.
Cuttings Propagation
Cuttings taken from the parent plant can also be used for propagation. Select healthy stems and cut 4-6 inch pieces with a clean, sharp blade. Remove the bottom leaves and dip the cut end in rooting hormone powder. Plant the cuttings in a well-draining potting mix and ensure it retains moisture. Keep them in a warm location with bright, indirect light and maintain the humidity by covering them with a plastic bag or a cloche. Once new growth appears, gradually harden off the plants by increasing the exposure to direct sunlight.
Air Layering
Air layering is a method of propagation that involves making a cut on a mature stem and wrapping it in moist sphagnum moss and plastic wrap to encourage root formation. Once roots have developed, cut the stem below the rooted area and pot the new plant. This method is slower than others but is useful for plants that are hard to root.
Propagation of Clerodendrum cephalanthum Oliv. subsp. cephalanthum is easy and straightforward. With proper care and attention, the new plants will flourish and produce beautiful flowers and fruits.
Disease Management
Clerodendrum cephalanthum Oliv. subsp. cephalanthum is susceptible to various fungal diseases that can hamper its growth and flowering. The most common fungal diseases that affect the plant are leaf spot, powdery mildew, and anthracnose.
Leaf spot: This fungal disease is characterized by brown or black spots on the leaves. To manage leaf spot, it is important to remove and destroy all the infected leaves. Apply a fungicide on the plant to prevent further spread of the disease.
Powdery mildew: This fungal disease appears as a white powdery substance on the leaves. It can affect the growth of the plant and reduce its flowering. To manage powdery mildew, prune the affected parts of the plant and apply a fungicide to prevent further spread.
Anthracnose: This fungal disease causes brown spots on the leaves and can lead to the death of the plant. To manage anthracnose, it is important to remove and destroy all the infected leaves. Apply a fungicide to prevent further spread of the disease.
Pest Management
Clerodendrum cephalanthum Oliv. subsp. cephalanthum is also susceptible to various pests that can damage the plant. The most common pests that affect the plant are mealybugs, scale insects, and spider mites.

Scale insects: These pests appear as bumps on the leaves and stems of the plant. They can also suck the sap from the plant and cause damage. To manage scale insects, prune the affected parts of the plant and wash the plant with a solution of soap and water. Apply an insecticide to prevent further infestation.
Spider mites: These pests can cause discoloration of the leaves and affect the growth of the plant. To manage spider mites, wash the plant with a solution of soap and water. Apply an insecticide to prevent further infestation.
