Hordeum Jubatum L. Ssp. Jubatum - Foxtail Barley

Overview

Hordeum jubatum L. ssp. jubatum, also known as Foxtail Barley or Squirrel-tail Barley, is a grass species native to North America. It is an annual or perennial that can grow up to 3 feet tall and is commonly found in grasslands, deserts, and disturbed areas.

Appearance

The Foxtail Barley has a distinctive, dense, and cylindrical seed head, measuring 2 to 6 inches in length, that resembles a fox's tail. The seed heads contain a multitude of awns, which are long, slender bristles that can measure up to 4 inches in length. The awns twist and coil tightly, giving the plant its characteristic appearance. The leaves are flat and narrow, measuring up to 9 inches long.

Uses

While Foxtail Barley is not typically used for food, it has several practical and ornamental uses. Native Americans used the plant's fibers to make cords and ropes, while European immigrants used it to stuff pillows and mattresses. Today, it is commonly used for erosion control and revegetation in disturbed areas. The plant's unique seed head is also highly valued in floral arrangements and crafts.

However, Foxtail Barley can be a nuisance in agricultural and residential settings as the awns can embed themselves in animal fur, clothing, and even skin, causing discomfort and potentially serious health issues. The plant can also decrease crop yields and contaminate hay.

In herbal medicine, Foxtail Barley is used for its diuretic and sedative properties. It has been traditionally used to treat urinary tract infections, edema, and anxiety. However, more research is needed to confirm its effectiveness and safety.

Light Requirements

Hordeum jubatum L. ssp. jubatum prefers full sunlight. They thrive in bright and direct sunlight for at least 8 hours a day. In areas that are not too hot, it can tolerate some partial shade, but this can slow down its growth process.

Soil Requirements

The plant prefers fertile, well-drained soil, rich in organic matter. It can also grow in a range of soil textures, from sand to clay, but loamy soil is the best for optimal growth. It requires soil pH between 6 and 7.5.

Water Requirements

The plant prefers evenly moist soil, so you need to keep it well-watered during its growth period. Watering once or twice a week, depending on the weather conditions, will suffice.

Temperature Requirements

Hordeum jubatum L. ssp. jubatum can grow in a wide range of temperatures, but the optimum temperature is between 15°C and 25°C. It can tolerate colder temperatures and even freezing but not too much, or it can reduce its growth rate. It cannot grow in extremely hot temperatures because it can quickly wilt and die.

Fertilizer Requirements

The plant does not demand much fertilizer; however, a regular supply of nitrogen fertilizer can help boost growth. You can apply a balanced 10-10-10 NPK (nitrogen, phosphorous, potassium) fertilizer during its growth period. Over-fertilizing can cause the plant to become too bushy and produce fewer flowers.

Cultivation methods

Hordeum jubatum L. ssp. jubatum, commonly known as foxtail barley, is a hardy, annual grass that is native to North America. It is generally easy to cultivate and can grow in a variety of soil types. The plant prefers full sunlight but can tolerate some shade. It is tolerant of drought but can also grow in areas with frequent rainfall.

To cultivate foxtail barley, you can either sow the seeds directly into the soil in the spring or start them indoors in the winter and transplant them to the garden in the spring. If sowing directly in the garden, prepare the soil by loosening it and removing any weeds. Scatter the seeds on top of the soil, then cover with a thin layer of soil. Keep the soil moist until the seeds germinate.

Watering needs

Hordeum jubatum L. ssp. jubatum requires moderate watering. It is tolerant of drought and can survive in dry conditions, but to encourage strong growth and prevent the plant from drying out, water it regularly when the soil surface feels dry to the touch. Avoid overwatering as it can lead to root rot.

Fertilization

Foxtail barley doesn't require much fertilization as it can grow in poor soil conditions. However, to encourage healthy growth, you can apply a balanced fertilizer, such as a 10-10-10 fertilizer, in early spring before new growth appears.

Pruning

Foxtail barley doesn't require pruning as it is an annual grass that dies back in the winter. However, to prevent reseeding and potential weed issues, you may want to cut back the seed heads before they fully mature and scatter the seeds. Use gardening shears to cut off the seed heads at their base, being careful not to damage the rest of the plant.

Propagation of Hordeum jubatum L. ssp. jubatum

Hordeum jubatum L. ssp. jubatum, also known as wild barley or squirrel-tail barley, is a perennial grass species that showcases beautiful panicles with striking bristle-like spikelets that resemble squirrel tails. If you're interested in growing this grass species, you'll be glad to know that it's relatively easy to propagate.

Propagation Methods

The following are the two primary methods used to propagate Hordeum jubatum L. ssp. jubatum:

Seed Propagation

The most common way to propagate Hordeum jubatum L. ssp. jubatum is by using seeds. The best time to sow the seeds is in the early spring when the soil has warmed up, making it easier for the seeds to germinate.

To start, prepare the soil by removing any weeds and rocks and then till the top three inches of soil. Scatter the seeds over the prepared soil, keeping in mind that this plant flourishes in partial shade to full sun. After scattering the seeds, cover them with a light layer (no more than 1/8 inch) of soil, then water.

It takes 10-14 days for the seeds to germinate. Prepare to water them daily until they're established. Once they've reached four inches in height, thin the seedlings (if desired) by leaving about 6-8 inches between each plant. By the second year, the plants will spread, and their roots will form a dense clump.

Division Propagation

Another way to propagate Hordeum jubatum L. ssp. jubatum is by division. This method works well when the plant is established and needs pruning. It's best done in the early spring or in the fall .

To begin, dig up the entire plant while taking care not to damage its roots. Once you've removed it from the ground, divide it into sections using a sharp knife or garden pliers. Ensure that each divided section has at least one new bud. Replant the divided sections immediately into prepared soil at the same depth as when they were previously planted, and then water them.

Expect new growth within a few weeks, and upon establishment, the plants will continue to thrive and spread.

Disease Management for Hordeum jubatum L. ssp. jubatum

Common diseases that affect Hordeum jubatum L. ssp. jubatum include stem rust, leaf rust, stem smut, and barley yellow dwarf virus. Stem rust is caused by the fungus Puccinia graminis, and it typically affects the stem of the plant, causing brownish-red lesions. Leaf rust, caused by the fungus Puccinia hordei, produces yellow-orange pustules on the leaves. Stem smut, caused by the fungus Ustilago hordei, results in distorted stems and leaves. Barley yellow dwarf virus, transmitted by aphids, causes stunted growth and yellowing of the leaves.

To manage these diseases, it is important to plant disease-resistant varieties of Hordeum jubatum. Cultural practices such as crop rotation, removing infected plant debris, and providing adequate irrigation can also help reduce disease incidence. Fungicides may be used in severe cases, but they should be applied according to labeled instructions and with caution to avoid the development of fungicide-resistant strains of fungi.

Pest Management for Hordeum jubatum L. ssp. jubatum

Pests that commonly affect Hordeum jubatum include aphids, mites, leafhoppers, and cereal rust mites. Aphids are sap-sucking insects that can transmit viruses, while mites and leafhoppers can cause damage through feeding. Cereal rust mites feed on the cells of the foliage, leading to loss of plant vigor.

To manage these pests, it is important to monitor plants regularly and take action at the first sign of infestation. Cultural practices such as removing infected plants, maintaining good weed control, and avoiding over-fertilization can help reduce pest populations. Insecticidal soaps and oils may be used to control aphids and mites, while pyrethroid insecticides may be used to control leafhoppers. Additionally, beneficial insects such as ladybugs and lacewings can be released to help control pest populations naturally.
