Digitaria marginata Link var. linkii Stapf is a warm-season grass that prefers full sunlight. It can tolerate partial shade, but prolonged shade may lead to weak, spindly growth, and reduced flowering and seed production.
Temperature requirements
This species grows best in warm temperatures of 20 to 30°C. It is susceptible to frost damage and cannot survive in areas with prolonged cold temperatures.
Soil requirements
Digitaria marginata Link var. linkii Stapf grows well in well-drained soils with a neutral pH range of 6.0 to 7.5. It can tolerate a range of soil types, from sandy loam to heavy clay soils. However, it grows best in fertile soils with high organic matter content. This grass does not tolerate waterlogged, saline, or highly alkaline soils.
Cultivation methods
Digitaria marginata Link var. linkii Stapf, also known as the Mexican crabgrass, is easy to cultivate and adapts to different growing conditions. It can grow in various soil types, including sandy, loam, or clay soil. The plant prefers warmth and thrives best in areas with high sun exposure. It is best to plant Digitaria marginata Link var. linkii Stapf directly in the soil during spring or summer, as they thrive best in warmer seasons.
Watering needs
The Mexican crabgrass requires moderate watering, and it's recommended to water the plant once every week. Overwatering may damage the roots and make them susceptible to diseases such as rot. It's essential to ensure that the soil is well-drained to prevent waterlogging, and watering should be done in the early morning or late afternoon.
Fertilization
Digitaria marginata Link var. linkii Stapf doesn't require much fertilizer, and it's recommended to use organic fertilizers. The application of fertilizers should be done once every six months, preferably during the growing season. Avoid overusing fertilizers as it may lead to burning of the roots
Pruning
Pruning Mexican crabgrass is not mandatory, but it can help in promoting healthy growth and keeping the plants tidy. It is recommended to prune or trim the plant annually or every two years during winter or early spring when the plant is dormant. Use clean, sharp pruning shears to avoid injuring the plant. Cut back any dead, damaged, or overgrown foliage while leaving enough foliage to help the plant regenerate.
Propagation of Digitaria marginata Link var. linkii Stapf
Digitaria marginata Link var. linkii Stapf, commonly known as Indian crowfoot grass, is a grass species that can be propagated through different methods. These methods include:
Seed propagation
The most common method of propagating Digitaria marginata is through seeds. The seeds should be collected from mature plants and sown in a well-draining soil mixture. The seeds should be covered lightly with soil and kept moist until germination. Germination usually occurs within two to three weeks, and the seedlings can then be transplanted to their permanent location.
Division propagation
Division is another propagation method that can be used for Digitaria marginata. This method involves digging up an established plant and dividing it into several smaller plants, each with its roots. The smaller plants can then be transplanted to their new location.
Vegetative propagation
Digitaria marginata can also be propagated vegetatively through stem cuttings. The stem cuttings should be taken from the parent plant and planted in a potting mixture. The stem cuttings should be kept moist and out of direct sunlight until new growth appears. Once new growth appears, the cuttings can be transplanted.
Disease Management
The plant Digitaria marginata Link var. linkii Stapf is susceptible to several diseases. The most common among them are:
- Leaf spot fungus
- Anthracnose fungus
- Root rot fungus
To manage these diseases, it is important to follow good cultural practices like maintaining proper plant spacing for good air ventilation, avoiding splashing water on the leaves while watering, and removing infected plant debris from the garden. Fungicides can also be applied to control the spread of these diseases. However, it is important to note that fungicides can negatively affect beneficial insect populations in the garden.
Pest Management
Several pests can affect the plant Digitaria marginata Link var. linkii Stapf. The most common among them are:
- Aphids
- Cutworms
- Armyworms
To manage these pests, it is important to encourage natural predators and parasites by planting companion plants that attract beneficial insects like lady beetles and lacewings. Physical barriers like row covers can also be used to prevent cutworms and armyworms from accessing the plants. Insecticidal soap or neem oil can also be applied to control aphids.
