Common Names:
Common names for Panicum dichotomum L. var. barbulatum (Michx.) Wood include bearded panicgrass, bearded panicum, and forked panicgrass.
Uses:
Panicum dichotomum L. var. barbulatum (Michx.) Wood is used as a forage and cover crop, and is also used for erosion control. The grass is palatable to livestock, making it a good grazing option. In addition, the grass provides habitat and food for wildlife, such as birds and small mammals.
General Appearance:
Panicum dichotomum L. var. barbulatum (Michx.) Wood is an annual grass that usually grows to be 1-3 feet tall. The stems are slender and erect, and the leaves are long and narrow. The inflorescence is a panicle that can be up to 10 inches long, with numerous branches that produce spikelets in pairs. The spikelets are small and oval-shaped, with long hairs that give the plant its "bearded" appearance. The roots of the plant are shallow and fibrous.
Light Requirements
Panicum dichotomum L. var. barbulatum (Michx.) Wood prefers full sun to partial shade to grow properly. It is a warm-season grass that requires at least six hours of direct sunlight every day for optimum growth. It is important to ensure that the plant receives enough sunlight to ensure healthy growth.
Temperature Requirements
The plant requires a warm climate to grow well. It is frost-sensitive and may die if exposed to cold temperatures. The ideal temperature range for Panicum dichotomum L. var. barbulatum (Michx.) Wood is between 25-30°C during the growing season. The plant can tolerate moderate heat but may suffer from heat stress if the temperatures rise beyond 35°C.
Soil Requirements
Panicum dichotomum L. var. barbulatum (Michx.) Wood is a versatile plant that can grow in a wide range of soil types. However, it prefers well-drained soils that are rich in organic matter. The soil pH should be between 6.0-7.0 for optimal growth. The plant can tolerate a wide range of soil textures, from sandy soils to heavy clay soils. Regular irrigation is required to ensure that the plant receives enough water to grow well.
Cultivation Methods
Panicum dichotomum L. var. barbulatum (Michx.) Wood is a drought-tolerant, warm-season grass that grows well in sandy or loamy soils with good drainage. This grass variety prefers a location that receives full sunlight to partial shade, and it is essential to plant it in the spring or early summer when the soil has warmed up sufficiently. The soil can be prepared by tilling once to twice and adding compost or organic matter.
Watering Needs
Although Panicum dichotomum L. var. barbulatum (Michx.) Wood can tolerate drought, regular watering promotes healthy growth. Newly planted grass should be watered generously to help establish a robust root system. Once the grass is established, it should be watered deeply but infrequently, about one inch of water per week. During extended periods of drought, additional water may be necessary to prevent the grass from drying out completely.
Fertilization
Panicum dichotomum L. var. barbulatum (Michx.) Wood prefers a slightly acidic soil with a pH range of 6.0 to 6.5. It responds well to regular fertilization during the growing season, with applications of nitrogen and phosphorus-rich fertilizers. A slow-release fertilizer can be applied at a rate of three to four pounds per 1,000 square feet once a year, ideally in the early growing season when the grass is actively growing. Avoid overfertilization as it can cause excessive leaf growth, reducing the plant's tolerance to drought and heat.
Pruning
Panicum dichotomum L. var. barbulatum (Michx.) Wood is a low-maintenance grass variety that requires minimal pruning. Dead or damaged leaves and stems can be removed as needed to maintain a neat appearance. If the grass becomes too tall, it can be cut back to a height of four to six inches in late winter or early spring before new growth appears. The grass blades should never be cut below the height of three inches as it may damage the crown of the plant, which can lead to a weakened or stunted plant. Pruning is generally unnecessary as this grass variety prefers a more natural look.
Propagation of Panicum dichotomum L. var. barbulatum (Michx.) Wood
Panicum dichotomum L. var. barbulatum (Michx.) Wood can be propagated by various methods, including seeds, stem cuttings, and division of root clumps.
Propagation by seeds
The most common way of propagating Panicum dichotomum L. var. barbulatum (Michx.) Wood is through seeds. The seeds are collected from mature plants and sown in well-prepared beds in the fall. The soil should be moist but well-drained. The seeds should be sown thinly and covered with a thin layer of soil. Germination occurs within two weeks, and the seedlings should be thinned out to one plant every couple of inches.
Propagation by stem cuttings
Panicum dichotomum L. var. barbulatum (Michx.) Wood can also be propagated by stem cuttings. The stems should be taken from mature plants and cut into pieces about four inches in length. The leaf blades and sheaths should be removed from the lower half of the stem, and the cutting should be planted in a pot filled with moist soil. The pot should be placed in a warm, well-lit area, and the cutting should root within two to four weeks.
Propagation by division of root clumps
Another method of propagating Panicum dichotomum L. var. barbulatum (Michx.) Wood is by division of root clumps. This method is usually done in the fall when the plant is dormant. The clump should be dug up, and the roots should be divided into smaller clumps. Each clump should have several shoots and a good root system. The clumps should be replanted in well-prepared soil, watered thoroughly, and placed in a shaded area until the plants have established.
Disease Management
Panicum dichotomum L. var. barbulatum (Michx.) Wood is susceptible to several diseases, which can lead to significant yield losses. Below are some of the common diseases that affect this plant and ways to manage them:
Leaf Rust
Leaf rust is a fungal disease that causes yellowish to brownish-orange pustules on the leaves. The pustules eventually turn brown and cause the leaves to wither. To manage this disease, it is essential to remove infected plant parts, apply fungicides, and plant resistant varieties.
Southern Blight
Southern blight is a soil-borne fungal disease that causes the plant to wilt. The roots and base of the plant become discolored, and a white fungal mat appears. To control this disease, remove infected plant parts, rotate crops, and apply fungicides.
Virus Diseases
Virus diseases are spread by insect vectors, and symptoms include stunting, yellowing, and leaf distortion. To control virus diseases, it is essential to remove infected plants, manage insect populations, and plant resistant varieties.
Pest Management
Panicum dichotomum L. var. barbulatum (Michx.) Wood is also susceptible to pests, which can lead to yield losses. Below are some of the common pests that affect this plant and ways to manage them:
Fall Armyworm
Fall armyworms are caterpillar pests that defoliate plants and cause significant yield losses. To control these pests, it is important to monitor plants regularly, apply insecticides, and plant resistant varieties.
Mites
Mites are small arthropods that feed on the plant's leaves and cause a mottled appearance. To control mite infestations, spray plants with miticides and maintain adequate soil moisture levels.
Grasshoppers
Grasshoppers are herbivores that feed on the plant's leaves, causing defoliation and yield losses. To control grasshopper populations, it is important to use bait traps, remove weeds, and apply insecticides.
