Origin
Eragrostis divaricata Cope, also known as Spreading Lovegrass, is a warm-season grass species native to North America.
Common Names
Besides Spreading Lovegrass, E. divaricata is also commonly known as Plains Lovegrass and Koda Lovegrass.
Appearance
Spreading Lovegrass is a low-growing perennial plant that can reach up to 30 inches in height. Its leaves are narrow and flat, with a blue-green color. The inflorescence of E. divaricata is a large, open, and pyramidal-shaped panicle that contains many spikelets. The grass turns a golden-brown in the fall and can add beautiful texture to any landscape.
Uses
Eragrostis divaricata is a valuable forage species for livestock and wildlife. It is also used in erosion control practices because of its extensive root system. In addition, the plant is used for ornamental purposes due to its aesthetic appeal.
Light Requirements
Eragrostis divaricata Cope typically grows in full sun to partial shade conditions.
Temperature Requirements
The plant prefers warm to hot temperatures ranging from 20 to 30 degrees Celsius for optimal growth.
Soil Requirements
Soil requirements for Eragrostis divaricata Cope are not very strict. It can grow in a variety of soil types ranging from sandy to loamy soils, but it prefers a well-draining soil. The pH range should be neutral to slightly acidic (pH 6.0-7.5).
Water Requirements
Regular watering is required for Eragrostis divaricata Cope, especially during the growing season. It prefers moderate to high moisture levels.
Fertilizer Requirements
The plant does not require fertilizer to thrive, but a slow-release fertilizer can be used during the growing season to boost growth.
Cultivation
Eragrostis divaricata Cope, also known as Spreading Lovegrass, is a perennial grass that is native to North America. It is best grown in full sun, in well-draining soil with a pH of 6.0 to 7.5. The plant can tolerate a wide range of soil types, including clay and sandy soils.
When planting lovegrass seeds, it is important to rake the soil lightly and sow the seeds at a depth of 1/8 inch. Keep the soil moist until the seeds germinate. Lovegrass can also be propagated by dividing clumps in the spring or fall.
Watering Needs
Eragrostis divaricata Cope is drought tolerant and can survive with minimal watering once established. However, it is recommended to provide regular watering during the plant's first growing season to help it establish a strong root system. After the plant has matured, watering can be reduced to once or twice a month, depending on weather conditions.
Fertilization
Lovegrass generally does not require fertilization. However, if the plant appears pale or weak, a mild application of a balanced fertilizer, such as a 10-10-10, can be applied in the spring and again in the fall.
Pruning
Eragrostis divaricata Cope does not require extensive pruning. However, removing dead or damaged foliage can improve the appearance of the plant and promote new growth. Pruning should be done in late fall, after the plant has gone dormant for the winter.
Propagation of Eragrostis Divaricata Cope
Eragrostis divaricata Cope is a type of ornamental grass that is commonly grown in gardens and landscapes. The propagation of this plant can be done using several methods, including:
Seed Propagation
One of the most common methods for propagating Eragrostis divaricata Cope is through seed propagation. To do this, collect mature seed heads during the fall season and store them in a cool, dry place until ready to use. In the early spring, scatter the seeds on the soil surface and lightly press them into the soil. Water the seeds lightly but consistently until they germinate, which usually takes up to three weeks. Thin the seedlings to a distance of about 12 inches apart and ensure they receive adequate sunlight and water for healthy growth.
Division Propagation
Another effective method for propagating Eragrostis divaricata Cope is through division propagation. Divide the clumps of mature plants during the early spring and replant the divisions immediately. Be sure to dig deeply to ensure that the plant's taproot is not damaged during the process. This method helps promote plant health and vigor and also provides an opportunity to enlarge a planting area or share plants with friends or family.
Cutting Propagation
Propagation of Eragrostis divaricata Cope through cuttings can also be done, but is less common. For this method, take softwood cuttings from the plant during the early summer when the plant's growth is most active. Use a rooting hormone before planting the cuttings in a well-draining soil mix and keep them moist and out of direct sunlight. In a few weeks, the cuttings will start to root, and they can be transplanted into individual containers or into the ground once they are well-established.
Disease Management
Eragrostis divaricata Cope is susceptible to diseases such as anthracnose, leaf spot, and rust.
To manage anthracnose, it is essential to remove and destroy infected plant parts, as the disease can survive until next season in plant debris. Fungicides such as Chlorothalonil can be used to manage anthracnose.
Leaf spot can be managed by avoiding overhead watering and proper pruning to increase air circulation. Fungicides such as Azoxystrobin can also be used to manage this disease.
Rust can be managed by planting resistant cultivars, pruning infected plant parts, and removing plant debris to reduce the spread of the disease. Fungicides such as Mancozeb can also be used to manage rust.
Pest Management
Eragrostis divaricata Cope is not generally affected by pests. However, spider mites can be a problem during hot and dry weather conditions.
To manage spider mites, it is essential to maintain a proper watering and fertilizing schedule to prevent stress to the plant. Insecticidal soap or neem oil can also be used to manage spider mites.
It is important to regularly monitor the plant for any signs of pest infestations, as early detection can prevent the spread of pests to nearby plants.
