Light Requirements
Paspalum pubescens Muhl. ex Willd. grows well in direct sunlight. The plant needs at least 6 hours of sunlight per day to develop fully. It can tolerate some shade but may not grow as well.
Soil Requirements
The plant prefers well-drained soils that are neutral to slightly alkaline. Paspalum pubescens Muhl. ex Willd. grows best in soils that are rich in organic matter. The plant can tolerate drought but does not grow well in waterlogged soils.
Temperature Requirements
Paspalum pubescens Muhl. ex Willd. can tolerate a wide range of temperatures. However, it grows best in temperatures that range from 20 to 30°C. The plant can tolerate frost but may not grow well in extremely cold temperatures.
Cultivation methods
Paspalum pubescens Muhl. ex Willd. is a warm-season grass species that thrives in subtropical and tropical regions. The plant can tolerate a wide range of soil types, but well-drained soils are preferable. It is recommended to plant Paspalum pubescens Muhl. ex Willd. in late spring or early summer after all spring frosts have passed.
The optimal conditions for the growth of Paspalum pubescens Muhl. ex Willd. require it to be cultivated under full sunlight exposure. The seedlings should be spaced 30-45 cm apart in rows. The germination of Paspalum pubescens Muhl. ex Willd. can take up to 14-21 days under optimal conditions.
Watering needs
Paspalum pubescens Muhl. ex Willd. requires frequent watering for optimum growth. Watering should not be too much or too little, as the plant can be sensitive to variations in water availability. Once it is established, watering needs rely on the soil type, temperature, and weather conditions in that area.
It is recommended to water the Paspalum pubescens Muhl. ex Willd. plants consistently, but not over-water them. Overwatering can lead to root and crown rot, wilting, yellowing, and stunted growth.
Fertilization
Fertilization plays a crucial role in the growth of Paspalum pubescens Muhl. ex Willd. Proper fertilization enhances seed production, growth, and quality. It is recommended to fertilize Paspalum pubescens Muhl. ex Willd. after the harvest, preferably using a slow-release fertilizer to allow for a slow and steady release of nutrients.
To calculate the correct fertilization dosage, it is essential to consider the soil type, climate, plant age, and the growth stages of the plant. Additionally, it is important to avoid over-fertilization, which can lead to short, weak, and diseased plants.
Pruning
Pruning of Paspalum pubescens Muhl. ex Willd. is essential to maintain plant health, vigor, and aesthetic looks. The cutting-down process is carried out to control the plant's height, overall shape, and to promote lateral shoot formation. A lawnmower can be used when pruning Paspalum pubescens Muhl. ex Willd. to encourage the lengthening of the lateral shoots.
Pruning of Paspalum pubescens Muhl. ex Willd. should be done before or during the growing season to allow for new growth and to reduce the risk of damaging newly formed leaves.
Propagation of Paspalum pubescens Muhl. ex Willd.
Paspalum pubescens Muhl. ex Willd., commonly known as hairy-fruit paspalum, is a warm-season perennial grass native to North America. It is commonly used for pastures, erosion control, and turfgrass. There are several methods of propagating Paspalum pubescens, including:
Seed Propagation
The most common method of propagating Paspalum pubescens is through seed. The seeds are typically planted in the spring or early summer when soil temperatures reach at least 60°F. The seeds should be planted at a depth of 1/4 to 1/2 inch in rows that are spaced 18 to 24 inches apart. Germination typically occurs within 10 to 14 days.
Vegetative Propagation
Paspalum pubescens can also be propagated vegetatively through stem cuttings or division. Stem cuttings should be taken from the plant during its active growth period and planted in a suitable rooting medium. Once roots have formed, the cuttings can be transplanted to their permanent location. Division involves separating the plant into smaller sections, each with its own root system. This method is typically used for older plants that have become too large or are in need of rejuvenation.
Sod Propagation
Paspalum pubescens can also be propagated through sod. Sod is typically harvested from healthy, mature plants and rolled out in the desired location. This method provides the advantage of an established root system, allowing for quicker establishment and growth.
Regardless of the propagation method used, Paspalum pubescens requires well-drained soil, adequate moisture, and regular fertilization to ensure successful establishment.
Disease Management
Paspalum pubescens Muhl. ex Willd. is susceptible to various diseases that can cause significant damage to the plant. The most common diseases that affect Paspalum pubescens are:
- Brown patch: This disease is caused by Rhizoctonia solani and manifests as circular patches with brownish-gray rings. Proper irrigation and fertilization practices can help prevent this disease. Fungicides such as azoxystrobin, flutolanil, and propiconazole can be used to manage brown patch.
- Pythium blight: This disease is caused by Pythium spp. and manifests as circular patches of wilted or water-soaked turf. Proper irrigation and drainage practices can help prevent this disease. Fungicides such as etridiazole and mefenoxam can be used to manage Pythium blight.
- Dollar spot: This disease is caused by Sclerotinia homoeocarpa and manifests as small, silver dollar-sized spots with reddish-brown margins. Proper irrigation and fertilization practices can help prevent this disease. Fungicides such as azoxystrobin, flutolanil, and propiconazole can be used to manage dollar spot.
Pest Management
Aside from diseases, Paspalum pubescens Muhl. ex Willd. can also be infested by pests that can damage the plant. The most common pests that affect Paspalum pubescens are:
- White grubs: These are the larvae of scarab beetles and they feed on the roots of Paspalum pubescens. Proper soil preparation and good cultural practices can help prevent white grub infestation. Insecticides such as imidacloprid and chlorantraniliprole can be used to manage white grubs.
- Moles: Moles feed on white grubs, which can indirectly damage Paspalum pubescens. Proper soil preparation and good cultural practices can help prevent mole infestation. Trapping and repelling are effective methods for managing moles.
- Armyworms: These pests feed on the blades of Paspalum pubescens, causing significant damage. Proper irrigation and fertilization practices can help prevent armyworm infestation. Insecticides such as bifenthrin and lambda-cyhalothrin can be used to manage armyworms.
