Origin
Schefflera myriantha (Baker) Drake var. attenuata Bernardi, commonly known as the Umbrella tree, is a tropical plant species that belongs to the family Araliaceae. It is native to the rainforests of Costa Rica, Central America, and other tropical regions of the world.
Common Names
The Schefflera myriantha var. attenuata is known by various names such as the Dwarf umbrella tree, Octopus tree, Parasol plant, and Starleaf schefflera.
Uses
The Schefflera myriantha var. attenuata is primarily cultivated as an ornamental plant. Its vibrant green foliage and lovely umbrella-shaped leaves make it a popular choice for indoor decoration. It is also a perfect plant for gardens and parks as it can grow up to 6 meters tall. Additionally, its leaves are often used in traditional medicines to treat various ailments such as asthma, coughs, and bronchitis.
General Appearance
The Schefflera myriantha var. attenuata is a small shrub, and its size varies from 0.6 meters to 1.8 meters tall. It has a woody stem and a compact, dense crown of leaves. The leaves are glossy and dark green with up to 8 leaflets, radiating from a central point, hence the name Umbrella tree. The plant produces small white or greenish flowers that grow in clusters and are followed by tiny, round fruits that change from green to black when ripe.
Light Requirements
Schefflera myriantha var. attenuata requires bright but indirect light for healthy growth. Direct sunlight can scorch the leaves, while insufficient light can cause the plant to become leggy and sparsely leaved. Therefore, it is best planted in an area that receives filtered or partially shaded sunlight.
Temperature Requirements
Schefflera myriantha var. attenuata prefers warm temperatures, with an optimal range between 65°F to 80°F (18.3°C to 26.7°C). It can survive in temperatures as low as 50°F (10°C), but prolonged exposure to low temperatures can damage the plant. It is essential to avoid exposing the plant to cold drafts, such as those from air conditioning units or open windows.
Soil Requirements
The soil for Schefflera myriantha var. attenuata should be well-draining while still retaining some moisture. The pH of the soil should be between 5.5 and 6.5. A recommended soil mix for this plant is a combination of peat moss and perlite. When planting, ensure the roots are loosely spread out and not compacted.
Cultivation Methods
Schefflera myriantha (Baker) Drake var. attenuata Bernardi, commonly known as the Umbrella tree, is a popular houseplant and is relatively easy to grow. The plant prefers bright, indirect sunlight. It does well in well-drained, moist soil with a slightly acidic to neutral pH.
When planting, it is recommended to use a potting mix that is rich in organic matter. The plant can grow up to 10-12 feet if left unchecked. It is best to provide support to the plant as it grows, either by staking or providing a trellis or a moss pole.
Watering Needs
Schefflera myriantha (Baker) Drake var. attenuata Bernardi needs moderate watering. Overwatering can cause root rot, so it is best to maintain moist soil, allowing the top inch of the soil to dry out before watering again. The frequency of watering depends on the weather, humidity, and soil type. It is always a good idea to check the soil before watering the plant.
Fertilization
Regular fertilization is essential for Schefflera myriantha (Baker) Drake var. attenuata Bernardi to thrive. Use a balanced, water-soluble fertilizer once every two weeks during the growing season (spring to fall). During the dormancy period (winter), reduce the frequency of fertilization to once a month.
Pruning
Pruning is not necessary for Schefflera myriantha (Baker) Drake var. attenuata Bernardi, but it can help control the plant's size and shape. If the plant has outgrown its space, it is recommended to prune the top or tip of the plant. This will encourage side branching and make the plant bushier. Pruning is best done during the growing season but should be done sparingly.
Propagation of Schefflera myriantha var. attenuata Bernardi
Schefflera myriantha var. attenuata is a popular houseplant due to its attractive foliage and low maintenance. Propagation of this plant can be achieved through several methods:
Propagating from stem cuttings:
Stem cuttings is the most common method of propagating Schefflera myriantha var. attenuata. Stem cuttings should be taken from healthy, disease-free plants and should be at least 6 inches long with at least 2 leaves attached. The cuttings should be dipped in rooting hormone and planted in a pot with a well-draining soil mix. Water regularly and keep the soil moist until the cuttings take root and begin to show new growth, which usually takes 4-6 weeks.
Propagating by air layering:
Air layering is a propagation method that involves inducing roots to form on a stem. Choose the stem to air layer where leaves emerge. Use a sharp knife to make a 1/3 incision through the stem and wrap moist sphagnum moss around the cut. Cover the moss with plastic wrap and secure it tightly above and below the moss. Wait until roots emerge from the moss ball, remove the wrap, and then cut below the roots to separate the new plant from the parent plant.
Propagating from seeds:
Propagation from seed is also possible, but it is not commonly used since it is not guaranteed to produce plants identical to the parent. Seeds should be removed from ripe fruit and planted in a well-draining soil mix. Keep the soil moist and warm, and germination should occur within 1-2 weeks.
Disease and Pest Management for Schefflera myriantha var. attenuata
Schefflera myriantha var. attenuata, commonly known as the Umbrella Tree, is an evergreen shrub that is highly susceptible to pests and diseases. Regular care and disease management practices are the key to preventing pest infestations and keeping the plant healthy.
Common Pests
Some of the common pests that attack Schefflera myriantha var. attenuata are:
- Aphids: They suck the sap from the plant and cause the leaves to curl and distort. Regularly spraying the plant with a strong stream of water and using insecticidal soap helps control them.
- Scale: They form a protective coating and feed on the plant sap leading to yellow leaves. Wiping the plant with a cotton swab dipped in alcohol or neem oil helps in controlling them.
- Spider Mites: If the leaves appear dusty and discolored, it is a sign of spider mites. Regularly spraying the plant with water and increasing the humidity around the plant helps prevent them.
- Mealybugs: They cause yellowing and stunted growth. Using neem oil or insecticidal soap controls them.
Common Diseases
Schefflera myriantha var. attenuata is susceptible to some diseases such as:
- Leaf Spot: It causes small brown spots on the leaves that merge and form larger necrotic areas. Regularly removing the affected leaves and spraying the plant with a copper fungicide helps prevent it.
- Root Rot: It causes the roots to rot leading to wilting and death of the plant. Avoid overwatering and increase the soil drainage to prevent it.
- Powdery Mildew: A white powdery substance on the leaves indicates the disease. Regularly spraying the plant with a fungicide and maintaining good air circulation helps prevent it.
Overall, it is recommended to regularly inspect the plant for any signs of pests or diseases and take necessary measures promptly to control the issue. Proper care and maintenance can keep the plant healthy and thriving for years.
