Origin and Common Names

Digitaria nemoralis Henrard is a type of grass that belongs to the Poaceae family. The plant is native to Africa but it can also be found in other countries such as India and Australia. It is also commonly known as velvet fingergrass, velvetgrass, and woodland fingergrass.

General Appearance

The grass grows in clumps and its height ranges from 1 to 4 feet. Its leaves are narrow, flat, and elongated, measuring about 2 to 15 centimeters long and 1 to 9 millimeters wide. The plant is characterized by its velvety or hairy texture that covers the leaves, giving it a soft appearance. Its stem is slender and fuzzy, and it produces small flowers that are arranged in a spike-like cluster.

Uses

Digitaria nemoralis Henrard is commonly used as a forage grass for livestock and wildlife. It is high in nutrients and can be a good source of food for grazing animals. The grass is also used for erosion control and as a ground cover in gardens and landscaping. In some cultures, the plant is used for medicinal purposes such as treating wounds and fever.

Light Requirements

Digitaria nemoralis Henrard is a plant species that thrives very well under full sunlight exposure. This plant requires at least six hours of direct sunlight per day to grow, bloom, and produce seeds.

Temperature Needs

The ideal temperature range for Digitaria nemoralis Henrard growth is between 20°C and 28°C. This plant is sensitive to low temperatures and frost, which can damage its foliage and roots.

Soil Requirements

Digitaria nemoralis Henrard prefers well-drained soils with a neutral to slightly acidic pH of around 6 to 7.5. The soil should be moist but not waterlogged, as this can cause root rot and affect plant growth. Additionally, the plant does not do well in nutrient-poor soils, so regular fertilization may be necessary for optimal growth.

Cultivation

Digitaria nemoralis Henrard, commonly referred to as the forest finger grass, is an annual warm-season grass. It thrives well in tropical and subtropical regions and is suitable for cultivation as a pasture grass, cover crop, or lawn grass. The grass requires full sun exposure, and it grows well in well-draining soils that are rich in organic matter.

Watering Needs

The Digitaria nemoralis Henrard grass requires regular watering throughout its growing season to maintain its lush green color. Watering should be done once or twice a week, depending on the prevailing weather conditions. During extended periods of drought or hot weather, the grass requires more frequent watering to maintain its health and vigor.

Fertilization

Fertilization is a critical aspect of cultivating healthy Digitaria nemoralis Henrard grass. A balanced fertilizer with nitrogen, phosphorus, and potassium should be applied during the grass's growing season to promote healthy growth. Additionally, the application of compost or organic matter can also help improve soil quality and provide vital nutrients to the grass.

Pruning

Pruning is not a necessary activity when cultivating Digitaria nemoralis Henrard grass. However, it is beneficial to remove any dead or diseased leaves and stems and to mow the grass down periodically to control its height. Mowing should be done at a height of between 2-3 inches to encourage healthy regrowth and maintain the grass's lush appearance.

Propagation of Digitaria nemoralis Henrard

Digitaria nemoralis Henrard, commonly known as woodland finger grass, is a warm-season grass that can be propagated through seeds or vegetative means.

Seed Propagation

The seeds of Digitaria nemoralis Henrard can be collected from mature seed heads when they have turned brown. The seeds should be cleaned and can be directly sown into the soil in the spring when the temperature reaches around 16°C (60°F). The seeds should be scattered lightly on the soil surface and lightly covered with a layer of soil to ensure good seed-to-soil contact. The soil should be kept moist until the seeds germinate, which usually takes around two weeks.

Vegetative Propagation

Digitaria nemoralis Henrard can also be propagated vegetatively by division or cuttings.

Division method involves separating rooted clumps of the plant and planting them in new locations. This method is best done in the spring when the plant starts to grow actively. The clumps should be dug out, and the roots and shoots should be separated by gently pulling them apart. The individual clumps should be replanted in a new location at the same depth as they were previously growing, and they should be watered well.

The cutting method is suitable for propagating larger plantings. The cuttings should be taken from the new growth of the plant in the spring or early summer, approximately 10-15 cm (4-6 inches) long. The cuttings should be planted into well-draining soil and kept moist until they start to grow new roots.

Regardless of the propagation method used, it is important to ensure that the newly propagated plants are watered regularly until they have developed a healthy root system to support their growth.

Disease and pest management for Digitaria nemoralis Henrard

Common diseases that can affect Digitaria nemoralis Henrard include fungal diseases such as leaf spot and root rot. These diseases can be caused by over-watering or poor drainage, particularly in waterlogged soils. To manage fungal diseases, it is important to keep the plant in well-drained soil and avoid over-watering. If the plant is already affected, removing affected leaves and treating with fungicide can help control the spread of the disease.

Pests such as grasshoppers, aphids, and whiteflies can attack Digitaria nemoralis Henrard, causing damage to the leaves and stems. To manage pests, monitoring the plant regularly can help detect infestations early on. Treating with insecticidal soap or neem oil can help control pests. Encouraging natural predators such as ladybugs and lacewings can also help manage pest populations.

In addition to fungal diseases and pests, Digitaria nemoralis Henrard can also be affected by environmental stressors such as drought and extreme temperatures. To prevent damage from these stressors, it is important to provide the plant with adequate water and protection from extreme temperatures.
