Clerodendrum lelyi Hutch. prefers a moderate to bright light exposure. It thrives well in partially shaded areas with bright, indirect light. Avoid exposing the plant to direct sunlight for extended hours, especially during the hot afternoons.
Temperature Range
The plant can adapt to a broad range of temperatures but thrives in temperatures between 18°C - 24°C. During the winter months, the plant requires temperatures that do not go below 10°C, which can cause the leaves to drop. In contrast, temperatures above 30°C might cause the plant to wilt, and buds might not survive the hot temperatures.
Soil Requirements
Clerodendrum lelyi Hutch. requires well-draining soils, such as sandy and loamy soils, with a pH range of 6.5 - 7.5. The soil should be rich in organic matter and should be kept continuously moist but not waterlogged. Using a potting mix that contains vermiculite or perlite can help enhance drainage and aeration.
Cultivation Methods
Clerodendrum lelyi Hutch. prefers to be grown in full sun or partial shade and well-draining soil. It can be propagated by stem cuttings or seeds. The best time to propagate the plant is in the spring or early summer when the plant is actively growing. When planting, it is advisable to loosen the soil and mix in some compost or organic fertilizer to the planting hole. The plant should be watered thoroughly after planting, and the soil around the plant should be kept moist until it is established.
Watering Needs
Clerodendrum lelyi Hutch. requires moderate watering, especially during the growing season. It is important to ensure that the soil is moist but not waterlogged. The plant can tolerate short periods of drought, but prolonged dry periods can have a negative impact on the plant's growth. The best time to water the plant is early morning or late evening when the sunlight is not too strong.
Fertilization
Clerodendrum lelyi Hutch. benefits from regular fertilization to support its growth and development. It is recommended to fertilize the plant every month during the growing season with a balanced fertilizer, such as a 10-10-10 or 20-20-20 formulation. Before application, ensure that the soil is moist, and avoid fertilizing during hot, dry weather. Additionally, it is advisable to reduce fertilization during the winter months when the plant is dormant.
Pruning
Clerodendrum lelyi Hutch. requires minimal pruning. However, if necessary, prune the plant in the early spring before new growth begins. Remove any damaged or dead branches, and shape the plant to the desired size and form. It is important to avoid excessive pruning as it can reduce the plant's flowering ability.
Propagation of Clerodendrum lelyi Hutch.
Clerodendrum lelyi Hutch., commonly known as Glory Bower, is native to the tropical regions of East Africa. It is an evergreen shrub with a magnificent display of scarlet and orange-red flowers, making it a popular ornamental plant.
Propagation by Seeds
The easiest and most common method of propagation for Clerodendrum lelyi is by seeds. The seeds can be collected from the plant when the fruits start to turn brown and dry. The seeds need to be sown in well-draining soil mix in a warm and humid environment. It is recommended to cover the seeds with a thin layer of soil and keep them moist until they germinate. The seedlings should be transplanted into larger pots or into the ground when they are large enough.
Propagation by Cuttings
The Clerodendrum lelyi can also be propagated by cuttings taken from semi-hardwood or mature stems of the plant. Cuttings should be around 10-15 cm long, with a few leaves kept on the top. The cuttings should be dipped in a rooting hormone and planted in well-draining soil mix. The cuttings should be kept in a warm and humid environment and watered regularly until they develop roots. Once roots have developed, the new plants should be transplanted into larger pots or into the ground.
Propagation by Layering
Another method of propagation for Clerodendrum lelyi is layering. This involves bending a stem down and securing it into contact with the ground. The area where the stem touches the soil should be scratched or wounded, and the wound should be covered by soil mix and kept moist. The stem will eventually develop roots and can be separated from the parent plant and transplanted into a new container or into the ground.
Overall, Clerodendrum lelyi Hutch. is a relatively easy plant to propagate by seeds, cuttings, or layering. With proper care and attention, these methods can result in many new plants to add to your ornamental garden.
