Paspalum Platyphyllum Griseb., Non J.a. Schultes - >>urochloa Platyphylla

Origin and common names

Paspalum platyphyllum Griseb., non J.A. Schultes, also known as the broadleaf paspalum or flatstem paspalum, is a species of tropical grass native to South America. It can be found in a range of habitats, including moist forests and wetlands, as well as disturbed areas like roadsides and pastures.

General appearance

Broadleaf paspalum is a perennial grass that can grow up to 1.5 meters tall. It has a flat stem that gives the plant its common name, and the leaves are long and narrow with rough, serrated edges. The inflorescence is a spike-like arrangement of small flowers that can vary in color from green to purplish-brown.

Uses

Broadleaf paspalum has several traditional medicinal uses in South America, where it is used to treat conditions like fever, diarrhea, and respiratory problems. The plant is also used as forage for livestock in areas where it occurs naturally, and it has been introduced to other parts of the world as a forage crop. Additionally, the root system of this species can help stabilize soil and prevent erosion in areas prone to landslides or heavy rainfall.here

Light Requirements

Paspalum platyphyllum Griseb. requires full sun to grow and thrive. It does not tolerate shady conditions well and can suffer from stunted growth.

Temperature Requirements

The plant has a preference for warm climates, with temperatures ranging from 20-30°C being ideal. It is not frost-tolerant and requires protection during cold winters.

Soil Requirements

Paspalum platyphyllum Griseb. grows best in well-drained soils with a pH range of 5.5-7.5. It is not particularly picky about soil type and can grow in sand, loam, or clay soils as long as they are well-drained. The plant prefers soils that are rich in organic matter, and benefits from regular fertilization to encourage healthy growth.

Cultivation Methods for Paspalum platyphyllum Griseb.

Paspalum platyphyllum Griseb. requires a well-draining soil mix, a sunny location, and protection from extreme heat and cold. The plant should be grown in a container with at least one drainage hole to prevent root rot. It can be propagated through dividing the clumps or by planting fresh seeds.

Watering Needs for Paspalum platyphyllum Griseb.

The plant should be watered regularly to keep the soil moist but not waterlogged. During the summer, the frequency of watering should be increased, while during the winter, the plant can be watered less often. The soil should be allowed to dry slightly between watering sessions to prevent root rot.

Fertilization of Paspalum platyphyllum Griseb.

Paspalum platyphyllum Griseb. benefits from regular fertilization during the growing season. A balanced fertilizer with a ratio of 10-10-10 or 20-20-20 can be applied every two weeks during the growing season. Slow-release fertilizers can be used instead, following the package instructions carefully.

Pruning Paspalum platyphyllum Griseb.

Pruning Paspalum platyphyllum Griseb. is not necessary apart from removing any brown or yellow leaves or dead stems. This should be done with a clean, sharp pair of pruning shears, taking care not to damage the healthy parts of the plant. Overzealous pruning can damage the plant or even kill it, so it should be avoided.

Propagation of Paspalum Platyphyllum Griseb.

Paspalum platyphyllum Griseb. is a clump-forming perennial grass that is native to Central and South America. It is commonly known as "Bahiagrass" and is often used for forage and turf. There are several methods for propagating Bahiagrass including seed, vegetative propagation, and sod.

Seed Propagation

The most common way to propagate Bahiagrass is through seed. Seed propagation is easy and cost-effective but can take longer to establish than other methods. The seed should be planted in the spring or early summer when the soil temperature is warm (around 65 degrees Fahrenheit).

The seed can be broadcast or overseeded onto a prepared seedbed or directly onto an established lawn. It should be lightly covered with soil and kept moist until it germinates. Once germinated, Bahiagrass requires regular watering until it is established.

Vegetative Propagation

Bahiagrass can also be propagated vegetatively using plugs or sprigs. This method involves taking small pieces of the plant and rooting them in the soil. It is a quicker way to establish a new lawn but can be more expensive than seeding.

To propagate vegetatively, small plugs or sprigs are taken from an established lawn and planted in the desired location. The area should be watered regularly and kept moist until the plugs are established. Once established, the Bahiagrass will spread and fill in the area.

Sod Propagation

Sod propagation is the quickest way to establish Bahiagrass but is also the most expensive. Sod is essentially small pieces of turf that are cut and rolled up, ready to be transplanted.

To establish a lawn using sod, the area must be prepared by removing any old grass or weeds and leveling the soil. The sod is then laid in a staggered pattern to avoid visible seams. The sod should be watered heavily after installation and kept moist until it is established.

Regardless of the method of propagation, Bahiagrass requires regular watering and maintenance until it is established. Once established, Bahiagrass is drought tolerant and requires little maintenance.

Disease and Pest Management for Paspalum platyphyllum Griseb.

Paspalum platyphyllum Griseb., non J.A. Schultes, commonly referred to as broadleaf paspalum, is a type of grass that is commonly found in wetland areas. Like any other plant, it is susceptible to diseases and pests that can affect its growth and productivity. Here are some common diseases and pests that might affect the plant and suggestions on how to manage them:

Diseases

Leaf Spot

Leaf spot is a common disease that affects Paspalum platyphyllum. It is caused by a fungus called Bipolaris spp. The fungus causes small, round or oval spots on the leaves of the plant, which can merge and form large brown patches. The infected leaves eventually die and fall off, leading to defoliation of the plant.

To manage leaf spot, it is important to keep the plant healthy by providing it with adequate nutrients and water. Fungal sprays can also be used to control leaf spot.

Rust

Rust is a fungal disease that affects the leaves and stems of Paspalum platyphyllum. It is characterized by the appearance of small, yellowish spots or pustules on the leaves. As the disease progresses, the spots turn reddish-brown and cause the leaves to wither and die.

To manage rust, it is important to remove the infected leaves and stems and destroy them. Fungicides can also be used to control rust.

Pests

Armyworms

Armyworms are common pests that feed on the leaves of Paspalum platyphyllum. The larvae of the armyworms are known to cause damage to the leaves, leading to a reduction in plant growth and productivity.

To manage armyworms, it is important to regularly monitor the plant for signs of infestation. Chemical sprays can be used to control the pest.

Sod Webworms

Sod webworms are another type of pest that feeds on the leaves of Paspalum platyphyllum. The larvae of the sod webworms cause damage to the leaves and stems of the plant, leading to reduced growth and productivity.

To manage sod webworms, it is important to keep the plant healthy by providing it with adequate nutrients and water. Chemical sprays can also be used to control the pest.

Overall, the key to managing diseases and pests that affect Paspalum platyphyllum is to maintain a healthy plant through proper cultivation and monitoring. By doing so, the plant will be better able to withstand attacks from diseases and pests, leading to improved growth and productivity.
