Oplismenus Loliaceus (lam.) P.beauv.

Origin

Oplismenus loliaceus (Lam.) P.Beauv., commonly known as basketgrass or creeping dith, is a species of grass native to Africa, Asia, and Australia.

Common Names

Other common names include creeping spear-grass, satingrass, and witchgrass.

Uses

Oplismenus loliaceus is used as a groundcover plant in lawns and gardens, particularly in shaded areas. It can also be used to prevent soil erosion on steep slopes. Additionally, it is known to be used in traditional medicine in some cultures as a treatment for skin conditions and as a diuretic.

General Appearance

The plant is a perennial grass that grows up to 30 centimeters tall. It has slender stems that are 1 to 2 millimeters in diameter. The leaves are dark green in color and often have a glossy or shiny appearance. The leaf blades are 2.5 to 10 centimeters long and 5 to 15 millimeters wide. The inflorescence consists of several racemes that are up to 10 centimeters long. The flowers are green or purplish in color and have a slightly furry appearance. The fruit is a small caryopsis that is approximately 1.5 millimeters in diameter.

Light Requirements

Oplismenus loliaceus is a shade-tolerant plant species and grows best in partial shade to full shade environments. It cannot tolerate direct sunlight for extended periods and can get damaged if exposed to it for too long. Therefore, it is better to plant it in areas with diffused light or dappled shade.

Temperature Requirements

This plant species is native to tropical and subtropical regions and prefers warm temperatures. The ideal temperature range for its growth is between 20°C to 28°C. It is essential to keep the temperature consistent and avoid sudden changes as this can affect the plant's growth and development.

Soil Requirements

Oplismenus loliaceus can grow in a wide range of soil types. However, it thrives in well-drained, moist soils rich in organic matter content. Soil pH should be slightly acidic to neutral, ranging between 6.0 to 7.0. The ideal soil type would be sandy loam or loamy sand.

Cultivation Methods

Oplismenus loliaceus, commonly known as basket grass, is a low-maintenance ornamental grass that can be grown both indoors and outdoors. It prefers well-drained soil and partial shade. The plant can be propagated through rhizomes or seeds.

For indoor cultivation, the plant should be grown in a pot with well-draining soil and placed in a spot with indirect sunlight. For outdoor cultivation, the plant can be introduced to a garden bed or grown in a pot on the balcony, patio, or deck.

Watering Needs

Oplismenus loliaceus requires moderate watering. Water the plant once a week thoroughly. Ensure that the soil is moist, but not waterlogged.

If the plant is grown in a pot, ensure that the pot has proper drainage holes. The soil should not retain moisture for an extended period as it could lead to root rot.

Fertilization

It is recommended that you fertilize the plant every two months during the growing season. Use a balanced, slow-release fertilizer for the best results. Follow the instructions on the fertilizer packaging.

Additionally, use organic matter such as compost to boost soil fertility. Ensure that the compost reaches the plant's roots.

Pruning

Oplismenus loliaceus does not require pruning except for aesthetic purposes. If you want to manage the plant's size or retain its shape, prune the plant's leaves using garden shears or scissors.

Additionally, remove dead or damaged leaves regularly. This facilitates air circulation within the plant, preventing fungal and bacterial infections from developing.

Propagation of Oplismenus loliaceus (Lam.) P.Beauv.

Oplismenus loliaceus (Lam.) P.Beauv. can be propagated through various methods which include:

Division

Division is one of the simplest and most effective ways to propagate Oplismenus loliaceus (Lam.) P.Beauv. This method involves separating the clumps of the plant into smaller sections and replanting them. The best time to divide Oplismenus loliaceus (Lam.) P.Beauv. is during the spring season when the plant starts to grow actively. Each section should have roots and leaves. Make sure to plant the divided sections at the same depth as the mother plant and water them well after planting.

Seed

Oplismenus loliaceus (Lam.) P.Beauv. can also be propagated by seed. The seeds of this plant are small and can be sown directly into the soil. The best time to plant the seeds is during the spring season when the soil starts to warm up. Before sowing, the soil must be loosened and well-draining to ensure that the seeds germinate well. Keep the soil moderately moist and the seeds should germinate within 2-3 weeks.

Cutting

Another way to propagate Oplismenus loliaceus (Lam.) P.Beauv. is through stem cuttings. Take stem cuttings of about 3-5 inches in length from the mother plant and remove the lower leaves. Dip the cut end of the stem into a rooting hormone, and plant it in a pot or container filled with well-draining potting soil. Keep the soil moderately moist and in a warm and bright location. The cutting should root and start to grow within a few weeks.

Disease Management

Oplismenus loliaceus is relatively resistant to disease, but some common fungal infections that may affect this plant include:

• Leaf Spot: This disease can occur due to the presence of various fungal pathogens, causing yellow spots on the leaves, which later turn brown or greyish in color.
• Root Rot: This is caused by waterlogging the soil, which leads to the decay of roots and other underground parts of the plants. The plant may wilt and die due to this infection.

To manage these diseases, some general practices include avoiding overwatering and maintaining proper soil drainage, cleaning up plant debris regularly, and practicing crop rotation.

Pest Management

While Oplismenus loliaceus may be relatively resistant to pests, some that may still affect it include:

• Aphids: They suck the sap from the plant's leaves, flowers, and stems, and produce a sticky substance called honeydew. This may lead to the growth of black mold and spread diseases.
• Mealybugs: They also feed on plant sap and can cause stunted growth, yellowing of the leaves, and leaf drop.

Some pest management methods that may be effective include spraying the plants with neem oil or a soap-water solution, removing affected plant parts, and introducing natural predators of the pests, such as ladybugs, lacewings, and spiders. It's important to carefully follow the instructions on any pest control products to avoid harming beneficial insects or the plant itself.
