Digitaria Diversinervis (nees) Stapf Var. Woodiana Henrard

Overview

Digitaria diversinervis (Nees) Stapf var. woodiana Henrard is a plant species that belongs to the Poaceae family. It is also known as the Wood's Crabgrass, a common name derived from its discoverer, Mr. E. S. Wood.

Origin

The Wood's Crabgrass is native to the African continent, particularly found in Angola, Botswana, Zambia, and Zimbabwe. It is also found in other parts of the world due to its ability to adapt to different climates and environments.

Appearance

The Wood's Crabgrass is a small plant that grows up to 40 cm in height. It has small, narrow leaves that are about 3 - 7 cm long. The leaves are green in color and are rolled inwards. The plant has small flowers that are less than 1 cm long, and they are arranged in compact clusters.

Uses

The Wood's Crabgrass has several uses, mainly as a forage crop for livestock. It is a valuable source of nutrition for cattle, sheep, and goats. The plant is also used for soil conservation, as it helps to prevent soil erosion due to its extensive root system. Furthermore, the seeds of the plant are used in some parts of Africa for medicinal purposes, primarily for treating fever and headache.

In conclusion, the Wood's Crabgrass is a versatile plant that has several uses. Its ability to adapt to different environments makes it a valuable crop for farmers and a vital source of food for livestock animals.

Light Requirements

Digitaria diversinervis var. woodiana requires full to partial sun exposure for optimal growth. It can tolerate partial shade, but too much shade can stunt its growth and reduce the number of leaves produced.

Temperature Requirements

This plant can grow in a wide range of temperatures, from 15 to 35°C (59 to 95°F). However, its ideal temperature range is between 20 to 30°C (68 to 86°F). It can survive light frost, but prolonged exposure to freezing temperatures can damage or kill the plant.

Soil Requirements

Digitaria diversinervis var. woodiana prefers well-draining sandy or loamy soils with a pH range of 6.0 to 7.5. It can grow in soils with low to moderate fertility but responds well to regular fertilization. It can tolerate drought conditions, but regular watering is preferred for optimal growth.

Cultivation methods

Digitaria diversinervis (Nees) Stapf var. woodiana Henrard grows best in full sun to partial shade in well-draining soils. The plant can tolerate a wide range of soil types, including clay, loam, or sand. It is best to plant the grass in a location where it can receive at least six hours of sun each day.

Watering needs

The plant needs regular watering during dry periods. It prefers moist soil, but it can also tolerate some drought. It is best to water the plant deeply, allowing the water to penetrate the soil at least six inches. However, it is essential to avoid overwatering the plant, as this can lead to root rot.

Fertilization

Digitaria diversinervis (Nees) Stapf var. woodiana Henrard does not need much fertilization, but adding some balanced fertilizer in the spring can help encourage healthy growth. It is best to apply a slow-release fertilizer to avoid burning the plant with too much fertilizer at once.

Pruning

This plant does not require much pruning, but it is best to remove any dead or damaged leaves or stems as needed. Additionally, it is advisable to cut the plant back to the ground in the fall to encourage new growth in the spring.

Propagation of Digitaria diversinervis var. woodiana Henrard

Digitaria diversinervis var. woodiana Henrard, commonly known as the broadleaf crabgrass, is a warm-season perennial grass that produces seeds every year. Propagating this plant can be done through either seed germination or vegetative propagation.

Propagation by Seed Germination

Seed germination is the most common method of propagating the broadleaf crabgrass. The seeds should be collected from matured plants during fall or early winter. The collected seeds should undergo stratification under cold temperature conditions to break their dormancy. After the seeds have been stratified, they should be sown in well-draining soil and covered with a thin layer of soil. The soil should be kept moist but not waterlogged until the seeds germinate. Germination usually occurs within 2-3 weeks. The plants can be transplanted to their permanent location after they have developed 2-3 leaves.

Propagation by Vegetative Propagation

Vegetative propagation of the broadleaf crabgrass can be done through tillers. These are small plants that grow from the base of the parent plant. Once the tillers have developed roots, they can be separated from the parent plant and transplanted to their permanent location. To ensure that the tillers grow roots, they should be placed in a moist environment and kept in a shaded area for the first few days until they establish roots.

Alternatively, rooting hormone can be applied to the tillers to encourage root growth. This method is effective when the plant population is small, and the plant is needed for a specific purpose, such as roadside stabilization or slope protection. However, this method is not appropriate for large-scale propagation of the broadleaf crabgrass.

Disease Management

Digitaria diversinervis (Nees) Stapf var. woodiana Henrard is susceptible to several diseases. The most common diseases are fungal and can cause leaf spots, stem rot, and root rot. To manage these diseases, it is important to ensure the plant has optimal growing conditions. This includes providing adequate drainage and avoiding overwatering, which can lead to waterlogged soil and the development of fungal diseases. Fungicides can also be used to manage fungal infections, but it is important to follow the manufacturer's instructions carefully.

Pest Management

The plant can also be affected by several pests, including grasshoppers, aphids, and spider mites. These pests can cause damage to the foliage, leading to reduced plant growth and yield. To manage these pests, it is recommended to use integrated pest management strategies. This can include using natural predators, such as ladybugs and lacewings, to control aphids and other insects.

Additionally, physical barriers, such as row covers, can be used to exclude grasshoppers and other large pests. In cases of severe infestation, insecticides may be necessary, but it is important to choose a product that is safe and effective for the plant and to follow the label instructions carefully.
