Temperature Requirements
The plant thrives in warm temperatures ranging between 60-80°F (15.5-26°C). It can tolerate temperatures as low as 50°F (10°C), but it should be protected from frost. It is advisable to keep the plant away from cold drafts and air conditioning units.
Soil Requirements
Clerodendrum capense G.Don grows best in well-draining soil that is rich in organic matter. The soil pH should be between 6.0-7.5, slightly acidic to neutral. The plant can tolerate slightly alkaline soil.
A mixture of peat moss, perlite, and vermiculite or potting soil mixed with perlite and sand can be used for planting. Ensure that the container has a drainage hole to allow excess water to drain out.
Cultivation Methods
Clerodendrum capense G.Don, commonly known as the Harlequin Glorybower or the Bleeding Glory Bower, is a tropical flowering plant that thrives in warm and humid environments. To cultivate this beautiful plant, you need to select a well-draining soil mix and a container with sufficient drainage holes. The plant grows best in bright, indirect sunlight, and temperatures ranging from 60 to 80 degrees Fahrenheit. Plant the Clerodendrum capense G.Don in a pot that is one size larger than its current container, and add some compost to the soil to create a fertile growing medium.
Watering Needs
To water the Clerodendrum capense G.Don, you need to maintain a consistent watering schedule. The plant likes moist soil, but it is essential to avoid overwatering, which can lead to root rot. Water the plant thoroughly when the top two inches of soil feel dry to the touch. Ensure that the water drains completely from the pot to prevent waterlogging. If you are unsure about how much water to give, wait until the leaves start to droop slightly, then water the plant.
Fertilization
Clerodendrum capense G.Don needs regular fertilization to grow and remain healthy. Apply a balanced, water-soluble fertilizer formulated for flowering plants every two months during the growing season, which typically runs from spring to summer. Reduce the frequency of fertilization during the fall and winter months. Ensure that you follow the manufacturer's instructions regarding the amount of fertilizer to use to avoid overfeeding the plant.
Pruning
To keep the Clerodendrum capense G.Don compact and bushy, prune it regularly. Prune back the previous year's growth to about half its length in late winter or early spring before the new growth appears. Remove any dead, diseased, or damaged branches as soon as you notice them. Prune away any suckers that emerge from the plant's base to focus the plant's growth upward. Regular pruning will promote the emergence of new growth, maintain the plant's shape, and enhance its flowering.
Propagation of Clerodendrum capense G.Don
Clerodendrum capense G.Don, also known as the butterfly clerodendrum, is a beautiful plant that is easy to propagate. There are various methods of propagation:
Seed propagation
The easiest and most common method of propagating Clerodendrum capense G.Don is through seeds. The seeds can be collected from mature fruits. After collecting the seeds, they should be dried and stored in a cool, dry place until ready for use. When sowing, the seeds should be planted in a well-draining soil mixture and kept moist. Germination can take up to two months.
Cuttings propagation
Another method of propagating Clerodendrum capense G.Don is through cuttings. The best time to take cuttings is in the spring or summer when the plant is actively growing. Cuttings should be taken from the softwood of the plant. The cutting should be about 6 inches long and should have a few leaves. Dip the cutting in rooting hormone and plant it in a well-draining soil mixture. Keep the soil moist and place the cutting in a warm, bright area, but not under direct sunlight. The roots should develop in about four to six weeks.
Air layering propagation
The third method of propagating Clerodendrum capense G.Don is through air layering. This method is best done in the spring. Choose a healthy stem with at least two nodes. Make a small cut through the bark on the stem, and apply rooting hormone on the exposed area. Cover the area with moist moss and wrap it in plastic. Wait until roots start to develop, and then cut the stem below the newly grown root mass. Plant the cutting in a well-draining soil mixture and keep it moist until established.
Disease and Pest Management for Clerodendrum capense G.Don
