  • skullToxicity

    • To humans

      Barley is generally considered safe for human consumption, and it is a common ingredient in many foods and beverages. However, in rare cases, some people may be allergic to barley, which can cause symptoms such as itching, hives, and difficulty breathing.
      Additionally, barley may contain mycotoxins, which are produced by fungi that can grow on the grain under certain conditions. Exposure to mycotoxins can be harmful to human health and may cause symptoms such as nausea, vomiting, and liver damage.

    • To pets

      Barley is commonly used as a feed grain for livestock, including cattle, sheep, and pigs. While barley is generally safe for animals to consume, it can be toxic in high amounts.
      Overfeeding barley to animals can lead to digestive problems such as bloating and diarrhea. In severe cases, it can also cause a condition known as acidosis, which occurs when the pH of the animal's rumen (stomach) drops too low. This can be life-threatening and may require veterinary treatment.
      Additionally, some types of barley may contain mycotoxins, which can be harmful to animals if ingested in large amounts.

  • water dropWater

    Barley should be watered regularly, but not over-watered. The soil should be kept consistently moist, but not waterlogged.
    How often to water depends on the growing conditions and soil type, but as a general rule, barley should be watered when the soil surface feels dry to the touch. In many cases, watering once a week should be sufficient.

  • sunLight

    Barley can tolerate a range of light conditions, from full sun to partial shade. In general, barley grows best in full sun, but it can also tolerate some shade. If growing barley indoors, it should be placed in a bright, sunny location, such as a south-facing window.

  • thermometerTemperature

    Barley is a cool-season crop and can tolerate cold temperatures, even freezing temperatures. It grows best in temperatures between 50-75°F (10-24°C). Barley can survive temperatures as low as 28°F (-2°C) and as high as 85°F (29°C). If growing barley indoors, the temperature should be kept within this range.

  • scissorsPruning

    Barley generally does not require pruning. However, if the plants become overcrowded, or if there is any diseased or damaged plant material, it can be removed to promote healthy growth. In general, barley plants will naturally self-prune as they grow.

  • bambooSoil

    Barley grows best in well-draining, fertile soil that is rich in organic matter. The ideal soil pH for barley is between 6.0 and 7.5. The soil should be loose and well-aerated, as this will help promote healthy root growth. If the soil is too heavy or compacted, the barley plants may not grow as well.

  • plantRepotting

    Barley does not typically require repotting, as it is usually grown outdoors in the ground.

  • water dropsHumidity & Misting

    Barley is a relatively low-maintenance plant that can tolerate a range of humidity levels. However, it generally prefers a moderate to low humidity level, as high humidity can promote the growth of fungal diseases. The ideal humidity range for barley is between 40% and 60%.

    Germination: The first stage in the life of barley is germination. This occurs when the barley seed is planted in moist soil and begins to absorb water. The seed then swells and the embryo within the seed starts to grow. Germination typically occurs within 3 to 7 days after planting, depending on the temperature and moisture level of the soil.

    Vegetative growth: After germination, the barley plant enters a phase of vegetative growth, during which it produces leaves, stems, and roots. This stage lasts for several weeks, and the plant will continue to grow until it reaches its maximum height of around 2 to 3 feet. During this stage, it is important to keep the soil moist and to fertilize the plants as needed.

    Flowering: Barley typically begins to flower in the spring, around 50 to 60 days after planting. During this stage, the plant produces spikes, which contain the flowers and eventually the grain. The flowers are wind-pollinated, and the plant produces large amounts of pollen.

    Grain development: After flowering, the barley plant enters the grain development stage, during which the flowers are fertilized and begin to develop into mature grains. This stage lasts for several weeks, and the grains will gradually become larger and heavier as they mature.

    Harvest: The final stage in the life of barley is the harvest, which typically occurs in the late summer or early fall, around 100 to 120 days after planting. The barley plants are cut down and the grains are harvested and processed for use in various products, such as beer, flour, and animal feed.

      Spring - early summer

    • Barley is typically propagated through seeds, and it is not commonly propagated through vegetative means such as cuttings or division.

      The ideal time to sow barley seeds is in the early spring, when the soil temperature is above 45°F (7°C). The specific months of propagation may vary depending on the climate and geographic location. In general, the best time to plant barley is in late winter to early spring, before the last frost date in the area.
