Light requirements
Erythrococca macrophylla requires a moderate amount of light for optimal growth. Direct sunlight for an extended period can damage the plant, but it also cannot tolerate deep shade. Thus, the ideal light requirement for the plant is partial shade or dappled shade. It grows naturally under the canopy of larger trees in areas with filtered light.
Temperature requirements
The ideal temperature range for the Erythrococca macrophylla plant is between 20 to 30 degrees Celsius. It cannot tolerate extremely cold or hot temperatures. In areas where temperatures fall below 10 degrees Celsius or exceed 35 degrees Celsius, the plant will struggle to survive. Maintaining optimal temperature is crucial for the proper growth and development of the plant.
Soil requirements
Erythrococca macrophylla prefers loose soil with good drainage. The soil should have a pH range of 5 to 7.5, which is neutral to slightly acidic soil. The plant can grow in various types of soil, including sandy or loamy soil. However, it cannot grow in heavy clayey soils or waterlogged soils. The plant also prefers a soil that has a high organic matter content. Adding compost or organic matter to the soil before planting can help improve its fertility and water-holding capacity.
Cultivation of Erythrococca Macrophylla
Erythrococca macrophylla, commonly known as 'Manawa,' is a tropical perennial climbing plant that is native to Malaysia, Indonesia, and Thailand. Its growth habit is mainly a vine that can climb up to 20 meters or more in height. Cultivation of this plant involves the following:
Soil Requirement
The plant thrives well in a fertile, well-drained soil that is slightly acidic or neutral. It is sensitive to waterlogged soil, so it is crucial to avoid overwatering and ensure proper drainage.
Watering Requirements
Erythrococca macrophylla requires consistent watering, especially during the dry months, to enable its growth and development. However, it is crucial to maintain a proper balance between watering and drainage. Overwatering can cause root rot, while underwatering can cause leaf shedding, especially during the hot season.
Fertilization
The plant requires regular fertilization to maintain its lush green foliage and healthy growth. Fertilizers containing high nitrogen levels, such as 20-10-10 or 14-14-14, are suitable to apply during the growing season. Additionally, a slow-release fertilizer application in the early spring is beneficial for the plant's overall health and development.
Pruning
Regular pruning is essential to maintain the plant's shape, promote healthy growth, and prevent tangling and overcrowding of the vines. It is advisable to prune away any dead or diseased plant material to prevent the spread of infections. Pruning the plant during the dormant season is ideal to encourage the development of new growth during the following growing season.
Propagation of Erythrococca macrophylla (Prain) Prain
Erythrococca macrophylla (Prain) Prain can easily be propagated through two main methods, which are:
Seeds
The plant produces seeds that are relatively easy to germinate and grow into new plants. To propagate Erythrococca macrophylla through seeds, follow the steps below:
- Collect mature fruits with viable seeds from the plant.
- Extract the seeds by removing the fleshy part of the fruit using a knife or your finger.
- Clean the seeds by washing them in water and drying them in a shaded area.
- Sow the seeds in pots filled with well-draining soil mix.
- Water the pots and place them in a shaded area to allow for germination.
- Once the seedlings are established, gradually increase light exposure by moving them to brighter areas.
Cuttings
Erythrococca macrophylla can also be propagated through stem cuttings. Here are the steps:
- Prepare a sterile and sharp cutting tool.
- Take cuttings from the tips of the stems of the parent plant. Make sure each cutting has a node and at least two leaves.
- Dip the cutting in rooting hormone to promote root growth.
- Place the cutting in well-draining soil mix and water the soil.
- Put a plastic bag over the pot to create a humid environment and keep the cutting from drying out.
- Place the pot in a shaded area to allow for root and shoot growth.
- Once the cutting has rooted and new growth has appeared, gradually increase light exposure by moving it to brighter areas.
Disease and Pest Management for Erythrococca macrophylla
Erythrococca macrophylla (Prain) Prain commonly known as the Arum-leaved erythrococca is a plant species that belongs to the family of Cornaceae. As with many other plants, it is susceptible to diseases and pests. Here are some of the common pests and diseases in Erythrococca macrophylla and ways of managing them:
Pests affecting Erythrococca macrophylla
Mites and Thrips: Mites and Thrips are tiny insects that can harm the plant by feeding on its leaves, flowers and fruit. They make small holes in the leaves, causing them to look discolored and to wilt. To manage this pest, remove and destroy affected leaves and try using insecticidal soap. Spray the plant with water frequently to keep the leaves clean.
Caterpillars: Caterpillars are another pest that can feed on the leaves and cause extensive damage to the plant. To manage this pest, remove and destroy the infected leaves, use Bacillus thuringiensis (Bt), which is a natural bacterial control for caterpillars. Also, frequently inspect the plant to prevent an outbreak of caterpillar infestation.
Mealybugs: Mealybugs infestations appear as white cotton fluffs or tiny bugs clusters on the leaves, flowers and stem. They feed on the sap of the plant causing it to die. To manage, it is recommended to regularly inspect the plant and remove infested flower, leaves, or stem and, using a cotton swab or small cloth dipped in alcohol, wipe the surface gently.
Diseases affecting Erythrococca macrophylla
Fusarium and Pythium: Fusarium and Pythium are two common soil borne fungal diseases that affect Erythrococca macrophylla and cause damage to the roots. The disease spreads when the soil is moist, leading to root rot and wilted stems. To manage this, avoid overwatering, ensure proper drainage on the ground. Treat with fungicide and remove and destroy the infected plants to prevent it from spreading.
Anthracnose: Anthracnose is a fungal disease that causes yellowing, defoliation, blotches, and cankers on the leaves. For effective management, remove and destroy the infected leaves and ensure good air circulation and sanitation practices are practiced. Treat with fungicide to prevent further spreading.
Caring for Erythrococca macrophylla may seem overwhelming, but with proper management, the plants can thrive and produce beautiful flowers.
