Common Names
The common names for Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. include Smooth brome, Hungarian brome or Austrian brome.
Appearance
Smooth brome typically grows up to 1-1.5m tall and has smooth, green leaves. The flower stem is usually erect with a nodding spike-like inflorescence that grows up to 15-20 cm long. The spikelets are about 1 cm long with six flowers in each spikelet. The glumes are unequal with the lower ones being shorter and narrower than the upper ones. It has fibrous and shallow roots that grow densely to form a tough grass sward.
Uses
Smooth brome has a high forage quality and is used for grazing and haymaking. It is also used as a soil stabilizer for its extensive fibrous root system that helps prevent soil erosion. Smooth brome is also used for land reclamation in areas that have been affected by fires, oil drilling or mining.

It can grow in sandy, loamy, or heavy clay soils and tolerate both acidic and alkaline pH levels. The plant prefers full to partial sun exposure and can thrive in regions with annual rainfall ranging from 300-600 mm. Planting can be done either through seeds or vegetative propagnation.
Watering Needs
Watering requirements for Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. are moderate. Water the plant deeply once a week during the growing season when the rainfall is insufficient. In areas with drought conditions, increase the watering frequency to twice a week. Avoid overwatering to prevent waterlogging, which can lead to root rot.
Fertilization
Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. is a low-maintenance plant that does not require frequent fertilization. However, to improve the soil's fertility, add a slow-release fertilizer during the planting season. Alternatively, you can top-dress the plant in early spring with a balanced fertilizer containing nitrogen, phosphorus, and potassium.
Pruning
Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. requires minimal pruning. However, to promote new growth and maintain the plant's shape, pruning can be done in early spring before the new growth begins. Use a pair of sharp pruning shears to remove the dead or damaged stems and cut back the overgrown branches. Avoid pruning too much as it can weaken the plant and affect its natural growth.
Propagation of Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr.
Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. is commonly known as Smooth Brome. It can be propagated through various methods such as seeds, division, and stem cuttings.
Propagation through Seeds
The most common method of propagation is through seeds. The seeds can either be sown directly in the ground or started indoors and then transplanted. It is best to sow the seeds in the spring or fall, as they require cold stratification to germinate.
The seeds should be sown at a depth of approximately ¼ inch and kept moist until germination occurs, which typically takes around two weeks. Once the seedlings have grown to the desired size, they can be transplanted into their permanent location.
Propagation through Division
Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. can also be propagated through division. This method involves separating the plant into smaller sections and replanting them in a new location.
The best time to divide the plant is in the spring or fall, when the plant is dormant. It is important to ensure that each section of the plant has a sufficient number of roots to survive after being replanted.
Propagation through Stem Cuttings
Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. can also be propagated through stem cuttings. This method involves taking a cutting from the parent plant and rooting it to create a new plant.
The cuttings should be taken in the spring or summer, and should be approximately 4-6 inches in length. The bottom of the cutting should be dipped in rooting hormone, and then placed in a soilless potting mix. The cutting should be kept moist until roots have developed, which typically takes around 4-6 weeks.
Overall, Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. can be propagated through seeds, division, and stem cuttings. Each method has its own advantages and disadvantages, so it is important to choose the method that best suits your needs and preferences.
Disease and Pest Management for Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr.
Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. is a perennial grass that is commonly known as smooth brome grass. It is grown as a forage crop and ornamental grass, and as with any plant, it is susceptible to diseases and pests. Here are some common diseases and pests that might affect the plant and ways to manage them.
Common Diseases
Fusarium Patch: This disease is caused by a fungus called Fusarium nivale and is characterized by yellow patches that turn reddish-brown. To manage this disease, avoid overwatering, and ensure good drainage. If the disease is severe, fungicides can be used.
Crown Rot: This disease is caused by fungi such as Fusarium, Rhizoctonia, and Pythium. Symptoms include wilting of leaves, yellowing, and stunting of plants. To manage this disease, practice good sanitation by removing infected plants. Rotate crops and avoid overhead irrigation.
Leaf Rust: This disease is caused by a fungus called Puccinia brachypodii. It is characterized by orange or yellow rust-colored spots on the leaves. To manage this disease, remove infected leaves and avoid overhead irrigation.
Common Pests
Armyworms: These pests are the larvae of moths and can cause significant damage to the grass by feeding on the leaves. To manage this pest, apply insecticides when they are at their most vulnerable stage of the lifecycle.
Grasshoppers: These pests feed on the leaves of the grass and can cause a lot of damage in a short amount of time. To manage this pest, apply insecticides when they are at their most vulnerable stage of the lifecycle. Removing weeds and other host plants can also prevent future infestations.
White Grubs: These pests are the larvae of beetles and feed on the roots of the grass. To manage this pest, use beneficial nematodes, which are soil-dwelling organisms that can kill white grubs. Fertilizing the soil and ensuring proper drainage can also prevent infestations.
In conclusion, managing diseases and pests is an essential part of maintaining the health of Bromus inermis Leyss. var. aristatus Schur ex Scribn. & Merr. To prevent any potential infestations and diseases, it is important to practice good sanitation, rotate crops, and apply pesticides and fungicides at the appropriate time.
