Overview
Clerodendrum macrostegium Schauer is a species of flowering plant that is native to the Philippines. It is a member of the Lamiaceae family and is commonly known as "Kupang" or "Upang" in the Philippines.Appearance
Clerodendrum macrostegium Schauer is a large shrub that can grow up to 4 meters tall. It has large, leathery leaves that are dark green in color and have a glossy texture. The plant produces clusters of white or pale pink flowers that are fragrant and attract butterflies and bees.Uses
The leaves and stem of Clerodendrum macrostegium Schauer have been traditionally used in Filipino folk medicine to treat a range of ailments including coughs, fever, and sore throat. The plant contains anti-inflammatory compounds and has been shown to have antioxidant properties. In addition to its medicinal uses, Clerodendrum macrostegium Schauer is also cultivated as an ornamental plant in gardens and parks.Cultivation
Clerodendrum macrostegium Schauer is a hardy plant that prefers warm, humid conditions and well-drained soil. It can be propagated from cuttings or by seed. The plant requires regular watering and benefits from occasional fertilizer applications to promote healthy growth and flowering.Light Requirements
Clerodendrum macrostegium Schauer thrives in a partially shaded area that receives bright light but not direct sunlight. You can also grow it in shaded areas, but the plant may not develop to its full potential and may produce fewer flowers.
Temperature Requirements
The plant thrives in temperatures ranging from 20°C to 26°C (68°F to 79°F). During the winter months, it is best to keep the plant in a warm place where temperatures do not drop below 10°C (50°F).If the temperature drops below 10°C, the plant may not survive.
Soil Requirements
Clerodendrum macrostegium Schauer thrives in slightly acidic to neutral soil with a pH range of 5.5 to 7.0. It prefers a well-draining soil that is rich in organic matter. You can amend the soil by adding organic matter such as compost or decomposed leaves to ensure good drainage. Also, the soil should be moist but not waterlogged. Watering the plant frequently but lightly will ensure that the soil remains moist.
Cultivation methods
Clerodendrum macrostegium Schauer, commonly referred to as Harlequin Glorybower, is a flowering plant that is native to China and Southeast Asia. It is a vigorous grower that requires well-draining fertile soil, partial to full sunlight, mild temperatures, and regular watering. Harlequin Glorybower plants are best grown in pots or containers because they can be invasive if planted directly in the ground.
Watering needs
Harlequin Glorybower requires regular watering to keep the soil evenly moist. It is important to avoid overwatering, as this may lead to root rot and other plant diseases. The plant should be watered thoroughly once the top one inch of soil feels dry to the touch. During the summer months, the plant may require frequent watering due to high temperatures and increased evaporation.
Fertilization
Harlequin Glorybower requires regular fertilization during the growing season to promote healthy growth and flowering. A balanced fertilizer with equal portions of nitrogen, phosphorus, and potassium (N-P-K) is recommended. Fertilizers should be applied every two weeks during the growing season, from spring through fall.
Pruning
Harlequin Glorybower requires regular pruning to promote healthy growth and flowering. Pruning can be done after flowering in the fall or late winter to early spring. The plant should be pruned to remove dead, damaged, or diseased branches, as well as to shape the plant and control its size. It is important to avoid heavy pruning, as this may reduce the plant's ability to flower. Light pruning will encourage the plant to produce more blooms.
Propagation of Clerodendrum macrostegium Schauer
Clerodendrum macrostegium Schauer can be propagated through various methods such as seed propagation, stem cuttings, and air layering.
Seed Propagation
The seeds of Clerodendrum macrostegium Schauer can be collected from mature fruits, which turn dark brownish when fully ripe. The collected seeds must be washed, cleaned, and dried off before planting. The seeds can be sown in a well-drained soil mix, keeping them moist but avoiding waterlogging. The best time for seed sowing is the rainy season.
Stem Cuttings
Stem cuttings can be taken from a healthy, mature Clerodendrum macrostegium Schauer plant during the active growth phase. The cutting should be around 6 inches in length, with at least two nodes and a few leaves. The base of the cutting should be dipped in rooting hormone powder and inserted into a well-draining potting mix. The cutting should be kept in a shaded location and misted regularly to maintain moisture levels. The cutting should root within 4-6 weeks and should be transplanted after 3-4 months.
Air Layering
Air layering is an effective propagation method for Clerodendrum macrostegium Schauer. Select a branch that is healthy and flexible, preferably from the middle of the plant. Remove the bark from a small section of the stem, apply rooting hormone, and wrap it in moist sphagnum moss. Secure the moss with a polythene sheet and tie it with twine to hold it in place. After a few weeks, the moss should be checked for the development of roots. Once the roots are visible, the branch can be cut off from the mother plant and potted into well-draining soil.
Disease Management:
Clerodendrum macrostegium Schauer is susceptible to certain diseases that may cause problems for the plant's overall health. Here are some of the common diseases to look out for:
- Powdery mildew: This disease is characterized by white, powdery spots on the leaves, stems, and flowers. To manage this condition, remove damaged foliage, and apply fungicides containing sulfur or neem oil.
- Root rot: Overwatering can cause the roots to rot, which can lead to the plant's death. To manage root rot, reduce watering frequency, and avoid letting the plant sit in water for too long.
- Canker: This is a fungal disease that causes dark, sunken patches on the stem, leaves, and flowers. Remove and discard infected parts of the plant, and prune the plant to permit adequate air circulation. Fungicides containing copper compounds might help manage canker.
- Leaf spots: Infected leaves exhibit brown spots with yellow halos. Remove and dispose of diseased leaves and apply fungicides containing copper to the plant.
Pest Management:
Clerodendrum macrostegium Schauer can attract various pests that can affect the plant's overall health. Here are some of the typical pests to be mindful of:
- Mites: These are tiny pests that suck sap from leaves. Mites can cause yellow leaves and defoliation in severe instances. To handle mites, apply insecticidal soaps or neem oil to the plant.
- Scale insects: They are tiny, tough, and armor-like with the capacity to kill the plant. The pests suck the sap from the plant leaving behind a sticky secretion. Apply a mixture of rubbing alcohol and dish soap to remove light infestations or use a mixture of neem oil to control large-scale outbreaks.
- Aphids: They are typical pests that suck the sap from the new plant growth. Controlling aphids can involve using pesticides or insecticidal soaps or spraying the plant with a strong stream of water can eliminate them.
- Caterpillars and beetles: These pests can eat the leaves of the plant, leading to defoliation. Handpick the insects and dispose of them, use insecticidal soaps or neem oil sprays to prevent infestations or enclose the plant in mesh netting to eliminate future attacks.
