This grass is commonly known as "Short-Spike Crabgrass" or simply "Crabgrass" due to its crab-like appearance when it grows low to the ground.Appearance
Digitaria brevipes is a short-lived perennial grass that grows up to 60 cm tall. Its stem is erect with short branches, while its leaves are smooth and range from 5-16 cm in length and 3-10 mm in width. The inflorescence is a spike-like structure that grows from the axils of the upper leaves and can measure up to 14 cm in length. The spikelets of the Digitaria brevipes are arranged in pairs, with the lower one being sterile and the upper one fertile.Uses
Digitaria brevipes is mainly grown as a forage crop for livestock, with its leaves and stems providing a source of nutritious fodder. This grass is also a common lawn weed in some regions and can be used to stabilize soil in areas prone to erosion due to its deep and fibrous root system. In some traditional medicine practices, heated leaves of Digitaria brevipes are used to treat abdominal pains and fever. Its seeds are collected and ground into flour to make bread, while some cultures use its roots in tea to improve digestion. In conclusion, Digitaria brevipes Mez is a versatile grass species with numerous benefits, including its use as a forage crop, stabilizer of soil and its many medicinal uses.Light Requirements
Digitaria brevipes Mez requires full exposure to sunlight for optimal growth. The plant needs at least 6 to 8 hours of direct sunlight every day. Therefore, it is recommended to place the plant in a location where it can get maximum sunlight exposure.
Temperature Requirements

Soil Requirements
Digitaria brevipes Mez prefers well-drained, moist, and fertile soil for optimum growth. The pH range required for the plant is between 6.0 and 7.5. Additionally, the plant needs soil that is rich in organic matter and nutrients. The soil should be mixed with compost, sand, and vermiculite to improve drainage and aeration.
Cultivation of Digitaria brevipes Mez
Digitaria brevipes Mez is a perennial grass commonly found in South America. It prefers warm temperatures and full sun exposure. The plant can be propagated through seeds or rhizomes. It is essential to select well-draining soil rich in organic matter to promote growth.
Watering Needs of Digitaria brevipes Mez
Digitaria brevipes Mez requires regular watering during the growth period. The plant is sensitive to drought and will require consistent watering to promote growth. However, overwatering can cause the roots to rot, leading to plant death. Watering should be done infrequently with sufficient amounts.
Fertilization of Digitaria brevipes Mez
The plant requires fertilizer to thrive and achieve maximum growth potential. A balanced fertilizer with an N-P-K ratio of 4-4-4 or 10-10-10 is recommended. The fertilizer should be applied during the growing season when the plant is actively growing. Over-fertilization can cause damage to the plant and should be avoided.
Pruning of Digitaria brevipes Mez
Pruning is not necessary for Digitaria brevipes Mez. The grass can grow up to 3 feet tall and is naturally resistant to pests and diseases. However, it is advisable to remove the dead or diseased leaves to promote healthy growth.
Propagation of Digitaria brevipes Mez
Digitaria brevipes Mez is a naturally occurring perennial plant that belongs to the family Poaceae. In general, this plant is propagated through seed and division methods.
Seed Propagation
Seed propagation is the most common and easiest method for D. brevipes. The seeds of the plant can be collected from the mature flowers that are growing on the plant. It is recommended to collect the seeds from the plant during the late summer or early fall. The collected seeds can then be sown on soil that is moist and not dry. Germination usually takes place within 15-20 days when conditions are favorable.
Division Method
Propagation through division method can be employed to propagate D. brevipes. This method requires dividing the roots of the plant carefully. The plant should be first lifted and then the roots can be separated with a sharp knife or garden scissors. The plant roots should be divided into smaller portions and can be planted in the desired location. The soil around the roots should be kept moist until the plant stabilizes.
In conclusion, seed propagation and division method are two commonly employed methods to propagate D. brevipes Mez. Careful attention should be given to the soil and moisture content for the plant to grow effectively and successfully after propagation.
Disease and Pest Management for Digitaria brevipes Mez
Digitaria brevipes Mez is a perennial grass that is immune to most pests and diseases. However, it can be vulnerable to a few diseases and pests such as the following:
Diseases
Fusarium Disease: This disease can cause the death of your Digitaria brevipes Mez. The signs of Fusarium disease are wilting, yellowing, and eventually drying up of the plant. To manage this disease, you should avoid overwatering your plant and apply fungicides early to prevent its spread.
Leaf Spot: Leaf spot is a fungal disease that appears on the leaves in the form of small, round, and dark spots. The spots can increase in size and spread to the entire leaf. To avoid this disease, you should avoid overhead watering and keep the foliage dry. You can also apply copper fungicides to treat the infected plant.
Pests
Cutworms: Cutworms are caterpillars of moths that chew off the roots of seedlings. To prevent cutworms from attacking your Digitaria brevipes Mez, you can apply insecticides around the base of your plant. You can also use traps to capture and kill them.
Grasshoppers: Grasshoppers are known to feed on the leaves of Digitaria brevipes Mez. To prevent them, you can physically remove them from your plant. You can also install barriers to prevent them from crawling up the stem of your plant.
By managing the above-mentioned pests and diseases, you will be able to keep your Digitaria brevipes Mez healthy and flourishing.
