Overview
Calamagrostis neglecta (Ehrh.) P.G. Gaertn., B. Mey. & Scherb. var. gracilis (Scribn.) Scribn. is a species of perennial grass that is native to North America, specifically found in the United States and Canada. It is commonly known as slender small-reed or in some instances, seldom soft-grass.
Appearance
Slender small-reed can grow up to 1 meter in height. It has thin, light green leaves that are flat and taper to a point, with a rough texture. The stem of the grass is slender and erect, with clustered spikelets at the top that are purplish-brown, beige, or pinkish in color. The inflorescence displays an airy panicle that reaches tall and narrow.
Uses
Slender small-reed has some uses, such as landscaping and erosion control due to its deep root system. The species' grass is also able to improve the soil due to its root structure by letting air and moisture into the soil. In addition, the slender small-reed is often used for ornamental purposes, as its airy panicle complements other plants in gardens.
Aside from these, the species has also been used as a habitat for wildlife, specifically birds, which nest and feed on the grass seeds.
However, this species of grass does not have significant economic importance, and it is not considered a useful grazing grass or crop for livestock feed.
Light Requirements
Calamagrostis neglecta var. gracilis thrives in full sunlight, but it can also tolerate partial shade. It is recommended to plant it in a location that receives at least six hours of direct sunlight each day for optimum growth.
Temperature Requirements
The plant prefers cool temperatures and can survive in a range of temperatures from 40°F to 90°F (4°C to 32°C). However, it is important to note that it does not tolerate extreme heat and may require extra watering during hot weather to prevent wilting.
Soil Requirements
Calamagrostis neglecta var. gracilis grows best in moist, well-draining soils with a pH range of 6.0 to 7.0. It can tolerate a range of soil types, including sandy, loamy, and clay soils. However, it is recommended to avoid planting in heavy clay soil to prevent waterlogging and root rot.
Furthermore, it is important to ensure proper soil moisture levels to avoid drought stress and wilting. Maintaining a layer of organic matter on top of the soil can help retain soil moisture and provide adequate nutrients to the plant.
Cultivation Methods
Calamagrostis neglecta var. gracilis prefers full sun to partial shade and well-drained soil. It grows best in USDA Hardiness Zones 3-7 but can adapt to other zones with proper care. It is a low maintenance plant that is tolerant of drought and salt. It can be grown from seed or by division of established clumps.
Watering Needs
Calamagrostis neglecta var. gracilis requires regular watering during its first growing season to help establish a deep root system. Once established, it is somewhat drought tolerant but should be watered deeply once a week during hot and dry weather. Overwatering can damage the plant, so it's crucial to ensure soil drainage is adequate.
Fertilization
Fertilization can help promote healthy growth in Calamagrostis neglecta var. gracilis, but it is not necessary. If you decide to fertilize, use a balanced, slow-release fertilizer in the early spring before new growth appears. Avoid fertilizing late in the growing season as this can interfere with the plant's natural hardening-off process and make it more susceptible to winter damage.
Pruning
Calamagrostis neglecta var. gracilis does not require extensive pruning to maintain its shape, but it can benefit from periodic maintenance pruning. Cut back the plant in late winter or early spring before new growth emerges to remove any dead or damaged foliage. If you notice any brown or diseased leaves during the growing season, remove them promptly to prevent the spread of the disease.
Propagation of Calamagrostis neglecta var. gracilis
Calamagrostis neglecta var. gracilis can be propagated through both seeds and division.
Propagation through seeds
The best time to collect the seeds of Calamagrostis neglecta var. gracilis is in mid-summer to early autumn. After collecting, the seeds should be dried and stored in a cool and dry place. They can be sown in trays of compost in the early spring or autumn. The seeds should be covered with a thin layer of soil and kept moist until they germinate, which usually takes 1-2 weeks. Once the seedlings are established, they can be transplanted into individual pots.
Propagation through division
Calamagrostis neglecta var. gracilis can also be propagated through division. This is best done in spring or autumn, when the plant is dormant. The clump should be dug up and divided into smaller sections, each containing some roots and shoots. The sections can be replanted in well-draining soil and watered regularly until they are established.
Both of these methods are effective in propagating Calamagrostis neglecta var. gracilis, and can help to create new and healthy plants that can be enjoyed in a variety of landscape settings.
Disease and Pest Management for Calamagrostis neglecta var. gracilis
Calamagrostis neglecta var. gracilis, commonly known as slender reed grass, is a hardy plant that is easy to grow. However, like any other plant, it is susceptible to diseases and pests. Here are some of the common diseases and pests that affect this plant and ways to manage them.
Diseases
Fusarium root rot: This fungal disease attacks the roots of the plant, causing wilting, yellowing, and stunted growth. To manage this disease, remove the infected plants and disinfect the soil before replanting. Also, avoid overwatering and improve soil drainage.
Crown rot: This disease affects the crown of the plant, causing it to rot. It is caused by a fungus that thrives in wet soil. The symptoms include yellowing, wilting, and death of the plant. To manage this disease, improve soil drainage, remove infected plants, and avoid overwatering.
Leaf spot: This disease is caused by a fungus that attacks the leaves of the plant, causing circular yellow spots. The spots gradually increase in size, turning brown or black. To manage this disease, remove infected leaves and improve air circulation around the plants.
Pests
Spider mites: These tiny pests can cause a lot of damage to the plant by sucking out its sap. The symptoms include yellowing and wilting of the leaves. To manage spider mites, spray the plant with a mixture of water and dish soap or neem oil. Also, improve air circulation around the plants.
Grasshoppers: These pests can cause extensive damage to the plant by eating its leaves and stems. To manage grasshoppers, use insecticidal soap or neem oil. You can also use row covers to protect the plants from these pests.
Slugs and snails: These pests feed on the leaves of the plant, leaving large holes in them. To manage slugs and snails, use slug and snail baits or traps. You can also remove them by hand, especially during the night when they are most active.
By following these disease and pest management tips, you can ensure that your Calamagrostis neglecta var. gracilis plants remain healthy and free from diseases and pests.
