Light Requirements
Eragrostis pectinacea var. tracyi requires full sun exposure for optimal growth. This grass species cannot tolerate shade and will struggle to grow in areas with limited sunlight.
Temperature Requirements
The optimal temperature range for Eragrostis pectinacea var. tracyi growth is between 70-90°F (21-32°C). However, this grass species can tolerate a wide range of temperatures as low as 40°F (4°C) and as high as 105°F (41°C).
Soil Requirements
Eragrostis pectinacea var. tracyi prefers soil that is well-drained and has a slightly acidic to neutral pH level between 5.5-7.5. This grass species can adapt to a variety of soil types, including sandy, loamy, and clay soils, but it thrives in nutrient-rich, loamy soil. It is important to note that this plant is not drought-tolerant and requires consistent moisture.
Cultivation methods
Eragrostis pectinacea (Michx.) Nees ex Steud. var. tracyi (A.S. Hitchc.) P.M. Peterson is a warm-season grass that thrives in well-drained soil and full sun. The plant can be direct seeded or transplanted in late spring when the soil has warmed up to at least 60°F (15.6°C). If you plan to direct seed, prepare the seedbed by removing weed and grasses and loosen the soil. Broadcast the seeds and lightly rake them to cover the seeds. For transplanting, start seeds indoors 4-6 weeks before the last spring frost, and transplant the seedlings once they have grown to about 3 inches (7.6 cm) tall.Watering needs
Eragrostis pectinacea (Michx.) Nees ex Steud. var. tracyi (A.S. Hitchc.) P.M. Peterson requires moderate watering to establish, but once established, it can tolerate drought. Water the plant deeply once a week or when the top inches of the soil feel dry. Avoid watering the plant too often or for a short time as it can lead to shallow root growth and poor plant health.Fertilization
Eragrostis pectinacea (Michx.) Nees ex Steud. var. tracyi (A.S. Hitchc.) P.M. Peterson is a low-maintenance plant that does not require frequent fertilization. However, if you choose to fertilize the plant, do it in early spring using a balanced slow-release fertilizer. Avoid fertilizing the plant in late summer and early fall, as it can stimulate new growth that will not survive the winter.Pruning
Eragrostis pectinacea (Michx.) Nees ex Steud. var. tracyi (A.S. Hitchc.) P.M. Peterson does not require pruning, but you can mow the plant to a height of 4-6 inches (10-15 cm) to promote denser growth. Mow the plant once in late winter or early spring before the new growth appears. However, avoid mowing the plant too short, as it can damage the roots and weaken the plant.Propagation of Eragrostis pectinacea var. tracyi
Eragrostis pectinacea var. tracyi is a warm-season grass that is native to North America. This plant can be propagated through different methods, including seed propagation, cutting propagation, and division.
Seed Propagation
Seed propagation is the easiest and most common method of propagating Eragrostis pectinacea var. tracyi. The seeds should be collected in late summer or early fall when they are mature. The seeds should be stored in a cool, dry place until the following spring.
In early spring, the seeds can be sown directly outdoors or started in a greenhouse. To start the seeds indoors, sow the seeds in trays filled with soilless potting mix, cover lightly with soil and keep moist. The trays should be kept in a warm, bright location. Once the seedlings have grown to a height of several inches, they can be transplanted outdoors.
Cutting Propagation
Cutting propagation is another method of propagating Eragrostis pectinacea var. tracyi. Cuttings should be taken in the spring or early summer when the plant is actively growing. Choose a stem that is at least 3 inches long, with multiple leaves.
To prepare the cutting, remove the lower leaves and dip the cut end in rooting hormone. The cutting should be placed in a pot filled with soilless potting mix and kept moist. The pot should be covered with a plastic bag to maintain humidity. Once roots have developed, the new plant can be transplanted to its permanent location.
Division
Division is another method of propagating Eragrostis pectinacea var. tracyi. This method involves dividing the clumps of grass in the spring or fall. Dig up the clump of grass and using a clean knife or spade, divide the clump into smaller sections. Each section should have its own roots and shoots. The divided sections can be planted directly in the ground or propagated in containers.
Disease Management
Various diseases can affect Eragrostis pectinacea var. tracyi, including:
- Leaf Spot - This disease is caused by fungi and results in the formation of dark spots on leaves, eventually leading to leaf death. To control leaf spot, remove infected leaves and apply a fungicide.
- Anthracnose - Anthracnose is caused by fungi and causes wilting and death of leaves, stems, and flowers. To manage anthracnose, remove infected plant parts and apply a fungicide.
- Root Rot - This disease is caused by fungi, and it affects the roots of plants, causing them to rot. To prevent root rot, avoid overwatering and ensure the plant is growing in well-drained soil.
Pest Management
Several pests can infest Eragrostis pectinacea var. tracyi, including:
- Sod Webworms - Sod webworms are the larvae of lawn moths, and they feed on grasses and plants. To control sod webworms, apply an insecticide or use biological control agents like nematodes.
- Aphids - Aphids are small insects that feed on plant sap, causing damage to plant tissues. To manage aphids, use insecticidal soap or neem oil, or introduce natural predators like ladybugs and lacewings.
- Cutworms - These caterpillars cut the stems of plants, causing damage and death. To control cutworms, use insecticides or biological control agents like Bacillus thuringiensis.
