Cultivation
Stipa nevadensis B.L. Johnson, commonly known as Nevada feathergrass, is a cool-season native grass that grows in dry to moderately moist soils within the Great Basin and Mojave Desert regions of North America. This plant can be grown both indoors and outdoors, either from seed or as young plants from local nurseries. The first step when growing this grass is to consider its adaptability to the environment and soil conditions. The ideal planting period is in the fall or early spring.
Watering Needs
Stipa nevadensis requires infrequent but deep irrigation, particularly during the summer months when moisture levels are low. It can tolerate drought conditions and actually prefers it to excess water. Water supply should be kept to a minimum, with just enough to prevent the grass from drying out or turning brown. Over-watering will cause root rot and other diseases.
Fertilization
Feathergrass is generally a light feeder and does not require a lot of fertilization. The soil must be tested to determine the type and amount of nutrients that are deficient. A slow-release fertilizer with a balanced NPK ratio (nitrogen, phosphorus, and potassium) applied every spring will provide ample nutrients for healthy growth. Organic fertilizers like compost or bonemeal will also deliver a steady release of nutrients into the soil.
Pruning
Pruning is not a necessary part of maintaining Stipa nevadensis. However, it is advisable to remove dead and damaged parts, weed overgrowth or controlling the spread of the plant. Deadhead spent blooms to encourage further growth and tidy the appearance of the plant. If you prefer the grass to be shorter, you can trim the top of the blade to achieve the desired height. Pruning is best done during late fall or winter before the new growth season starts.
Propagation of Stipa nevadensis B.L. Johnson
Stipa nevadensis B.L. Johnson, also known as Nevada feather grass, is a perennial grass species that is native to the Western United States. It is a popular ornamental grass that is commonly used in landscaping and requires minimal maintenance. If you are interested in propagating Stipa nevadensis, there are several methods you can use.
1. Seed Propagation
The easiest and most common way to propagate Stipa nevadensis is through seed propagation. This method involves collecting seed heads from the plant and sowing them in a well-draining soil mix. It is best to sow the seeds in the early spring, as this will give the plants a full growing season to establish themselves before winter. You can also sow the seeds in the fall, but the plants may not establish as well.
When sowing the seeds, make sure to moisten the soil mix before planting, and cover the seeds with a thin layer of soil. The seeds will germinate in three to four weeks, and you should see new growth within a few weeks after that. Once the seedlings have established themselves, you can transplant them to their permanent location.
2. Division
Another way to propagate Stipa nevadensis is through division. This method involves digging up an established clump of the plant and dividing it into smaller sections. This is best done in the early spring before new growth begins. You should use a sharp shovel or knife to gently divide the clump into smaller sections, each with its own set of roots. Make sure to plant the new sections in a well-draining soil mix and water them regularly until they have established themselves.
3. Cuttings
Propagation through cuttings is also possible, but it is less reliable than the other methods. This method involves taking stem cuttings from an established plant and rooting them in a soil mix. You should take the cuttings in the early spring before new growth begins, and make sure to dip the cuttings in a rooting hormone before planting them in the soil mix. Keep the soil moist and keep the cuttings in a warm, bright location until they have established themselves.
Overall, Stipa nevadensis is a relatively easy plant to propagate. Whether you choose to propagate through seed, division, or cuttings, you will be able to quickly add this beautiful ornamental grass to your garden.
Disease and Pest Management for Stipa nevadensis B.L. Johnson

Alongside providing ideal growing conditions, keeping an eye out for potential diseases and pests is essential to maintain healthy plants. Here are some of the common diseases and pests that might affect Stipa nevadensis and ways to manage them:
Common Diseases
Crown and Root Rot: Crown and root rot are caused by fungi that thrive in moist soil. The infected plant shows symptoms like wilted leaves, yellowing, and stunted growth. Proper soil drainage and watering practices are essential to prevent crown and root rot. Fungicides can be used as a preventive measure or to treat the infection.
Leaf Spots: Leaf spots occur due to different fungi species. The infected plant's leaves develop spots of various colors, sizes, and shapes. Good air circulation and watering practices help prevent leaf spot infections. Removing infected leaves, using fungicides, and avoiding overhead watering can also help manage leaf spots.
The Smut Disease: The smut disease appears as blackish or brownish masses on the plant’s leaves and stems. This disease spreads through fungal spores that move quickly through water and soil. Following proper sanitation practices such as removing infected plant debris and using fungicides can prevent smut disease.
Common Pests
Aphids: Aphids are tiny insects that suck sap from the plant's leaves causing them to wilt and curl. Regularly inspecting the plant's leaves and shoots and using insecticides or natural predators like ladybugs can help prevent aphid infestations.
Mites: Mites are small pests that feed on the plant's foliage, causing yellowing and decreased growth. They thrive in hot and dry weather. Proper watering and the use of pesticides or miticides can help manage mite infestations.
Slugs and Snails: Slugs and snails feed on the plant's leaves, leaving large holes in them. They are most active at night and can be prevented by removing their hiding spots like weedy areas. Handpicking, using barriers or slug baits can help control slug and snail populations.
In summary, managing diseases and pests for Stipa nevadensis requires a combination of different strategies. Preventive measures such as proper soil drainage and watering practices, proper sanitation, regular inspections, and using natural predators are effective disease and pest management strategies.
