Overview
Dichanthelium lanuginosum (Ell.) Gould var. fasciculatum (Torr.) Spellenberg, commonly known as Woolly panic grass or Woolly dichanthelium, is a species of perennial grass that is native to North America. It belongs to the family Poaceae
Common Names
Woolly panic grass, Woolly dichanthelium, Woolly rosette grass, and Woolly beard grass
Appearance
Woolly panic grass has a unique appearance and can grow up to two meters tall. It has long, hairy leaves and stems that are characteristic of the genus Dichanthelium. The stems tend to curve upwards and outward, with the seed heads forming at the ends of the flowering stems. The flowers themselves are small and inconspicuous with a greenish hue that blends well with the foliage.
Uses
Woolly panic grass is primarily used for ornamental purposes. It is known to attract butterflies and other pollinators to gardens. The grass can also be used in erosion control measures, as its extensive root system helps to stabilize soil. Its native ecosystem roles are that of a cover plant and forage for animals.
Light Requirements
Dichanthelium lanuginosum var. fasciculatum is a sun-loving plant that requires full sunlight to grow and thrive. It can tolerate some shade, but too much shade will cause the plant to become weak and spindly.
Temperature Requirements
The plant is native to the central and eastern regions of North America and can tolerate a wide range of temperatures, including hot summers and cold winters. However, it prefers moderate temperatures with an annual average of 14-21°C (57-70°F).
Soil Requirements
Dichanthelium lanuginosum var. fasciculatum grows best in well-drained soils that are rich in organic matter with a pH range of 5.5 to 6.5. The plant can tolerate a wide range of soil textures, from sandy to clay soils, but it prefers loamy soils that are rich in nutrients. Additionally, the plant is sensitive to soil salinity, making it unsuitable for growing in saline or alkaline soils.
Cultivation Methods
Dichanthelium lanuginosum (Ell.) Gould var. fasciculatum (Torr.) Spellenberg, also known as velvet panicum, is a native grass in the United States. It is a warm-season perennial grass that requires full sun exposure to grow. It prefers well-drained soils to thrive. Therefore, it is crucial to plant it in areas where the water does not accumulate. When planting, ensure you loosen the soil to a depth of at least 6 inches so that the roots can establish well.
Watering Needs
Watering is essential when it comes to cultivating velvet panicum. Once the plant is established, it requires moderate watering. During the summer season, you need to water at least twice a week if there is no rainfall. On the other hand, during the winter, you may need to reduce the watering frequency since the plant is dormant.
Fertilization
Fertilization is another crucial aspect when it comes to the cultivation of velvet panicum. It requires regular fertilization for proper growth and development. It would help if you used fertilizers that are high in nitrogen content, such as 16-4-8, 20-10-10, among others. You should fertilize at least once every three months when the plant is actively growing.
Pruning
Pruning is not necessary when it comes to velvet panicum. However, if you notice any dead or damaged foliage, you may need to remove them immediately. Also, you can occasionally cut back the grass to help it maintain a desirable form or size. It is advisable to prune the plant during the dormant season.
Propagation of Dichanthelium lanuginosum var. fasciculatum
Dichanthelium lanuginosum var. fasciculatum, commonly known as woolly panic grass, is a perennial grass native to North America. Propagation of this plant can be done in several ways:
Seed Propagation
Propagation of Dichanthelium lanuginosum var. fasciculatum from seeds is a common method. The seeds of the plant can be sown in spring or fall when the soil temperature is consistent. The seeds should be sown at a depth of ¼ inch and the bed should be kept moist until the seedlings appear. The seedlings can be transplanted when they are large enough to handle.
Division
Division is another method of propagation for Dichanthelium lanuginosum var. fasciculatum. In the spring, the plant can be divided into several sections using a spade or garden fork. Each section should contain a shoot and roots. The divided sections can be replanted in pots or directly in the ground.
Vegetative Propagation
Vegetative propagation is a method of propagation for Dichanthelium lanuginosum var. fasciculatum that involves rooting stem cuttings. The best time to take cuttings is in the summer months. The cuttings should be taken from healthy plants and rooted in moist potting soil. These cuttings can be transplanted once they have developed a strong root system.
Disease Management
Dichanthelium lanuginosum var. fasciculatum is generally a disease-resistant plant, but it can sometimes be susceptible to a few diseases. Common diseases that can affect this plant include:
- Rust: This fungal disease appears as yellowish-orange pustules on leaves and stems. To manage rust, remove and destroy infected plant parts, maintain good air circulation and avoid overhead watering.
- Leaf spot: This fungal disease causes circular, brown spots on the leaves. To manage leaf spot, avoid overhead watering, and remove and destroy infected plant parts. Fungicides may also be necessary.
- Root rot: This soil-borne disease causes the roots to rot and the plant to wilt. To manage root rot, improve soil drainage, avoid overwatering, and remove and destroy infected plant parts.
Pest Management
Like most plants, Dichanthelium lanuginosum var. fasciculatum is susceptible to pest attacks. Common pests that can affect this plant include:
- Grasshoppers: These insects can chew on the leaves and stems, causing significant damage. To manage grasshoppers, physically remove them by hand or use insecticides.
- Aphids: These small insects can suck the sap out of the plant, causing stunted growth. To manage aphids, use insecticidal soap or neem oil.
- Spider mites: These pests suck the sap out of the plant, causing leaves to turn yellow and dry out. To manage spider mites, use a forceful stream of water to knock them off the plant, or use insecticidal soap or neem oil.
Regular monitoring of Dichanthelium lanuginosum var. fasciculatum and early detection of diseases and pests can go a long way in managing them effectively.
