Common Names
Ixora synactica De Block is known by several common names in its native range. These include "Pinawarayan," "Damay," "Balukbalukan," and "Kumpai-kumpai" in the Philippines, and "Jejarum" and "Sangga Merah" in Malaysia and Indonesia.
Uses
Ixora synactica De Block is mostly used for ornamental purposes, as it produces a bright and long-lasting display of beautiful red flowers. In some areas where the plant is abundant, it is also utilized for traditional medicines. The leaves and roots of the plant are believed to have healing properties that can treat several conditions such as fever, headache, and skin diseases.
General Appearance
Ixora synactica De Block is a small to medium-sized shrub that can grow up to 2-3 meters in height. It has glossy and dark green leaves that are ovate in shape and can reach up to 12 cm in length. The plant produces clusters of small, bright-red flowers that bloom throughout the year, particularly during the rainy season. The flowers are tubular in shape and have four petals that form a star-like shape. The plant's fruits are small, round, and turn black when ripe.
Light Requirements
Ixora synactica De Block is a sun-loving plant that thrives in bright and direct sunlight. It needs at least 6 hours of sunlight per day. However, it cannot withstand prolonged exposure to direct sunlight during the hot summer months, leading to leaf scorching and drying. Therefore, it is best to give partial shade during extreme heat conditions.
Temperature Requirements
Ixora synactica De Block is a warm-weather plant that thrives well in tropical and subtropical conditions. It cannot tolerate freezing temperatures and prefers temperatures between 70 to 90°F. It is best to grow Ixora synactica De Block in a warm and humid environment.
Soil Requirements
Ixora synactica De Block prefers a well-draining soil that has a slightly acidic pH range between 5.5 and 6.5. The soil should be rich in organic matter to provide adequate nutrients for the plant's growth. Additionally, it needs consistent moisture to develop healthy roots. Therefore, it is best to keep the soil moist, but not waterlogged, by providing a regular water supply.
Cultivation Methods for Ixora synactica De Block
Ixora synactica De Block requires a warm and humid environment and is best suited for outdoor cultivation. It prefers well-draining soil that is rich in organic matter and slightly acidic. The plant can tolerate partial shade but thrives in full sun exposure.
It is essential to space out the plants adequately to allow for proper air circulation and prevent the spread of diseases.
Watering Needs for Ixora synactica De Block
During the growing season, Ixora synactica De Block requires regular watering to keep the soil moist. However, it is crucial not to over-water the plant as this can lead to root rot. It is essential to let the soil dry partially before providing additional water.
If the plant is cultivated indoors, it is essential to use water that is at room temperature to avoid shock.
Fertilization of Ixora synactica De Block
Ixora synactica De Block requires regular feeding with balanced fertilizer to promote healthy growth and flowering. Fertilizers that are high in potassium are the best for promoting a vibrant bloom, while nitrogen-rich fertilizers promote leafy growth.
It is essential to follow the manufacturer's instructions carefully when applying fertilizers, as over-fertilization can lead to salt buildup and damage the roots.
Pruning of Ixora synactica De Block
Pruning Ixora synactica De Block is essential to maintain its shape and promote healthy growth. It is best to prune immediately after flowering to avoid damaging the buds for the next season. Remove any diseased or dead wood to prevent the spread of diseases.
If the plant becomes leggy or overgrown, prune back by up to one-third of its size, focusing on the inner growth rather than the outer foliage.
Propagation of Ixora synactica De Block
Ixora synactica De Block is a beautiful and easy-to-grow plant that produces clusters of small, star-shaped flowers. It can be propagated through a variety of methods, including:
Seed propagation
One of the easiest ways to propagate Ixora synactica De Block is through seed propagation. The seeds are readily available and can be purchased from a reputable seed supplier. To propagate Ixora synactica De Block from seeds, follow these steps:
- Soak the seeds overnight in water to soften the outer shell.
- Plant the seeds in a well-draining soil mix. Cover with a thin layer of soil.
- Water the soil thoroughly and cover the container with plastic wrap to create a greenhouse effect.
- Place the container in a warm, bright area, and keep the soil moist. In a few weeks, you should start to see the seeds sprout.
- After a few weeks, remove the plastic wrap and continue to care for the seedlings as you would with any young plant.
Cuttings propagation
Another way to propagate Ixora synactica De Block is through stem cuttings. Here's how:
- Select a healthy stem from the parent plant and cut it at an angle using a clean, sharp pair of scissors or pruning shears.
- Remove the leaves from the bottom half of the stem.
- Dip the end of the stem into rooting hormone powder.
- Plant the stem in a container filled with moist, well-draining soil mix.
- Cover the container with a plastic bag to create a greenhouse effect.
- Place the container in a bright, warm area, and keep the soil moist.
- In a few weeks, you should start to see roots forming. At this point, you can remove the plastic bag and continue to care for the new plant as you would with any young plant.
Propagation of Ixora synactica De Block is an easy and rewarding way to grow this beautiful plant, and once established, it will provide you with gorgeous blooms year after year.
Disease and Pest Management for Ixora synactica De Block
Ixora synactica De Block, commonly known as Malay ixora, is a popular ornamental plant prized for its beautiful and fragrant flowers. Despite being relatively hardy, the plant can still fall prey to a variety of pests and diseases. Here are some common problems you might encounter and ways to manage them:
Common Diseases
Leaf Spot: Leaf spot is a fungal disease that causes small, circular, brown spots on the leaves. Severely infected leaves may fall off and reduce plant vigor. The disease is often spread by water splashing on the leaves. To manage leaf spot, remove and destroy infected leaves, improve air circulation through pruning, and avoid overhead watering.
Powdery Mildew: Powdery mildew is another fungal disease that causes a white, powdery fungus to appear on the leaves and flowers. It is often caused by high humidity and poor air circulation. To control powdery mildew, remove infected leaves and flowers, increase airflow, and avoid overhead watering. Fungicides can also be used to manage severe infections.
Bacterial Blight: Bacterial blight is a disease that causes wilting, blackened stems, and small, brown blotches on the leaves. It can be spread by infected pruning tools or insects. To manage bacterial blight, remove and destroy infected plant parts, disinfect pruning tools, and avoid handling plants when they are wet.
Common Pests
Aphids: Aphids are small, soft-bodied insects that suck plant sap and excrete a sticky honeydew that can cause fungal diseases. They are often found on the undersides of leaves and can be controlled by spraying with insecticidal soap or neem oil.
Mealybugs: Mealybugs are another sucking insect that can cause stunted growth and deformities. They are covered in white, waxy filaments and can be controlled by spraying with horticultural oil or insecticidal soap.
Spider Mites: Spider mites are tiny, spider-like insects that feed on the undersides of leaves, causing yellow stippling and eventual leaf drop. They thrive in dry, dusty conditions and can be controlled by spraying with a strong jet of water, or with miticides.
By staying vigilant and following good cultural practices, you can help ensure that your Ixora synactica De Block stays healthy and beautiful year-round.
