Overview of Digitaria adscendens var. fimbriata
Digitaria adscendens var. fimbriata, also known as the Fringed Crabgrass, is a species of weed in the Poaceae family. This plant is native to tropical America, but is also found in other parts of the world. It is considered an invasive species in many areas.
Common Names
The plant has numerous common names in different regions, including Fringed Crabgrass, Wire Grass, Fimbriate Fingergrass, and Scrambling Crabgrass. Some people also refer to it as a weed grass, because of its tendency to grow in disturbed areas like gardens, lawns, and roadsides.
Uses
Although it is generally considered a weed, Digitaria adscendens var. fimbriata does have some uses. In some parts of the world, it is used as a fodder for livestock. This plant also has medicinal properties in traditional medicine in some regions. For example, in Nigeria, the powdered leaves are used to treat skin infections, wounds, and fever.
Appearance
The Fringed Crabgrass has a creeping growth habit and can rapidly spread by producing runners. The leaves of this plant are long, narrow and pointed and its flower spikes are slender and often drooping. The flowers are green and form in dense clusters at the ends of the stems. It typically grows up to a height of 1.5 to 2 feet and prefers full sun exposure. Digitaria adscendens var. fimbriata can often be distinguished from other plants by its fringed leaf edges and long, wiry stems.
hereLight Requirements
The Digitaria adscendens (Kunth) Henrard var. fimbriata (Link) Cufod. plant thrives in full sunlight but can also tolerate partially shaded conditions. However, for optimal growth and development, it is recommended to plant the species in areas with direct exposure to sunlight.
Temperature Requirements
The plant prefers warm temperatures between 24°C to 32°C (75°F to 90°F). These temperatures promote growth as they enhance photosynthesis and other physiological processes that vitalize the plant. However, Digitaria adscendens can tolerate temperatures up to 38°C (100°F) and survive in temperatures as low as 12°C (54°F).
Soil Requirements
Digitaria adscendens (Kunth) Henrard var. fimbriata (Link) Cufod. prefers well-drained, fertile soils. It grows best in loamy soils that are neutral to slightly acidic, with a pH range of 6.5 to 7.0. Furthermore, the plant requires adequate soil moisture for optimal growth and development. However, excessive water can cause root rot, so ensure that the soil is well-draining to avoid standing water around the plant roots.
Cultivation Methods
Digitaria adscendens (Kunth) Henrard var. fimbriata (Link) Cufod. is a type of grass that is best grown in sunny or semi-shaded areas. It is easy to cultivate, and it can be grown from seeds or through vegetative propagation. When planting from seeds, it is best to sow them in well-drained soil during the spring or summer months. On the other hand, vegetative propagation includes transplanting the root system and stems of an existing plant to a new location.
Watering Needs
This grass plant requires moderate watering. It is best to let the soil dry before giving it more water to prevent it from getting waterlogged. The perfect watering schedule usually depends on the humidity, temperature, and amount of rainfall in the area. It is advisable to water in the early morning or late afternoon to avoid evaporation caused by the sun's heat.
Fertilization
Digitaria adscendens (Kunth) Henrard var. fimbriata (Link) Cufod. requires regular feeding to grow well. Fertilizers that are high in nitrogen are recommended, especially in the spring and summer months. It is best to apply fertilizers evenly throughout the soil to avoid burning the roots. The perfect feeding schedule is usually once a month, but it is best to check the manufacturer's instructions to ensure that the proper amounts are applied.
Pruning
Pruning of this grass plant is not necessary. However, for aesthetic purposes and to ensure its health, it is best to cut the grass regularly. It's recommended to remove any dead or yellowing leaves or any flowers that appear. Practising this helps to promote new growth and healthy development of the plant.
Propagation of Digitaria adscendens var. fimbriata:
Digitaria adscendens var. fimbriata is propagated by various means, including using seeds or vegetative methods.
Seeds Propagation:
Seeds are the most widely used method to propagate Digitaria adscendens var. fimbriata. The seeds are obtained from mature plants and sown directly into the soil at a depth of 1-2 cm. The best time to sow seeds is in the early rainy season when there is adequate moisture in the soil. Seeds are sown in rows, with a spacing of about 20 cm between them. This ensures that the plants have enough space to grow and receive enough sunlight.
Vegetative Propagation:
Digitaria adscendens var. fimbriata can also be propagated vegetatively using various methods, including stem cuttings or division of the clumps. Stem cuttings are taken from mature plants and planted horizontally into the soil, ensuring the nodes are in contact with the soil. The cuttings are kept moist until they develop roots, which usually takes about 3-4 weeks. Division of the clumps involves digging up mature plants and dividing them into smaller clumps, which are replanted in a suitable location.
Both methods of propagation have their advantages and disadvantages. Seed propagation is good for large scale planting, while vegetative propagation is suitable for small scale propagation or genetic conservation.
Disease Management
The plant Digitaria adscendens var. fimbriata is mostly susceptible to fungal diseases, which can cause leaf spot, stem rot, and root rot. These diseases can be managed by ensuring proper drainage, reducing humidity levels, and avoiding excess moisture around the roots of the plant. Additionally, avoid overcrowding plants, promote airflow, and remove any infected or dead plant debris to prevent the spread of the disease. Fungicides can also be used to control the spread of the disease, but they should be used as a last resort and only after consulting with a professional.
Pest Management
The most common pests that may affect the plant are spider mites, aphids, and mealybugs. Spider mites are known to suck the sap out of the leaves and cause them to turn yellow and dry up. Aphids and mealybugs are also known to feed on the sap of the plant, causing stunted growth and deformities. To manage these pests, monitor your plants regularly and remove any infected parts of the plant. Use a strong spray of water to remove the pests from the plant or use insecticidal soaps or natural insecticides to control them. It is important to conduct a thorough inspection of any new plants before introducing them to your garden, as pests and diseases can spread easily among plants.
