Valerian powder is an condiment that has been used for medicinal purposes for centuries. All corridor of the valerian factory are used medicinally, but the roots and rhizomes contain the most salutary composites. Valerian has dreamy,anti-anxiety, and sleep- promoting parcels, making it helpful for treating wakefulness, anxiety, and stress. Understanding where valerian grows stylish allows tillers to give the ideal conditions for the factory to thrive and produce the loftiest quality medicinal composites. This article will provide a brief background on valerian and discuss the optimal growing conditions, geographic distribution, and cultivation methods for producing excellent valerian plants.
General Information About Valerian
Valerian is a imperishable flowering factory that's native to Europe and corridor of Asia. The factory can grow up to 5 bases altitudinous and has fern- suchlike leaves with clusters of small white or pink flowers that bloom in summer. The name" valerian" is deduced from the Latin verb valere, meaning" to be strong" or" to be healthy." Valerian root was used as a drug during Greek and Roman times, with the first recorded medical use dating back to the 2nd century bulletin Hippocrates, Galen and other croakers of the classical period honored valerian’s capability to treat wakefulness, unease, temblors, and heart pulsations. During World War I and II, valerian was used in England to relieve stress and anxiety caused by air raids.Today, valerian remains one of the most popular herbal sedatives worldwide.
In order for valerian to develop its full concentration of active medicinal compounds, it requires specific growing conditions. Valerian grows best in loose, fertile soil with abundant organic matter. Well-drained, moist soil is ideal, as valerian roots can rot if exposed to standing water or soggy conditions. The plant thrives in soil with a neutral or slightly alkaline pH of 6.5-7.5. While valerian will tolerate partial shade, full sun exposure results in higher essential oil concentrations in the roots and rhizomes. Proper growing conditions will ensure valerian reaches full medicinal potency.
Ideal Growing Conditions for Valerian
Valerian grows best in loamy, well-drained soil rich in organic matter. The addition of compost or manure creates ideal growing conditions. Clay soils often drain poorly and retains too much moisture for valerian's liking. Sandy soils dry out too quickly. The stylish soils for valerian have a admixture of beach, ground, and complexion to give the nutrients, drainage, and humidity retention that valerian requires. Prior to planting, the soil should be cultivated to a depth of 12- 18 elevation to break up compacted layers and ameliorate aeration and drainage.
Valerian thrives best in neutral to slightly alkaline soils with a pH between 6.5-7.5. Acidic soils below pH 6.0 can inhibit growth and cause chlorosis, or yellowing of the foliage. If a soil test reveals the pH is too low, agricultural lime can be added to raise the pH to the target level. The lime should be thoroughly mixed into the soil 2-4 weeks before planting valerian.
Valerian requires consistently moist, but not saturated soil. Excess moisture will cause the roots to rot. The plants should receive 1-2 inches of water per week from rain or irrigation, with the soil drying slightly between waterings. Use drip irrigation or soaker hoses rather than overhead sprinklers to keep foliage dry and prevent disease. Mulching around plants helps moderate soil moisture and temperature.
While valerian will tolerate partial shade, full sun is ideal for maximum medicinal potency of the roots and rhizomes. Choose a site with 8 hours or more of direct sunlight each day. Morning sun is essential, with some afternoon shade acceptable to keep soil from completely drying out on hot days.
Valerian thrives in areas with cool summers and cold winters. Daytime temperatures of 65-70°F and nighttime temperatures around 55°F are optimal during the growing season. Valerian can tolerate brief temperature dips to -5°F over winter. Hot summer temperatures above 85°F slow growth and decrease essential oil production. Provide shade if growing valerian in warmer climates.
Geographic Distribution of Valerian
Valerian is native to Europe and parts of Asia. The plant grows wild in damp meadows and woodland areas from Sweden to the Mediterranean and across Russia, China, and India. Historical records trace the cultivation of medicinal valerian back over 2,000 years to Greece, Rome, and Asia Minor. The ancient Greeks likely spread valerian further across Europe. As demand for the herb grew over centuries, valerian could be found growing across much of continental Europe by the Middle Ages.
Valerian was brought to North America and Australia by early European settlers. It has naturalized across much of the United States and Canada, growing freely in fields and waste places. The transition zone from southern Canada into the northern U.S. provides an excellent climate for cultivating valerian. The herb also grows exceptionally well in the Pacific Northwest. Valerian has been able to adapt to a wide range of climate conditions outside its native range.
While valerian grows wild in damp areas across many parts of the world, the high demand for medicinal grade valerian has resulted in focused cultivation. The condiment is commercially grown in England, Eastern Europe, Russia, the Netherlands, the United States, and corridor of Asia. Oregon, Idaho, Washington, California, and the Great Lakes region are crucial valerian- producing areas in theU.S. Valerian grown in Russia and Eastern Europe is considered exceptionally high in medicinal quality.
Valerian is grown from root cuttings or seeds planted directly in the garden. For root cuttings, dig up valerian plants in late fall or early spring, removing young white rhizomes for replanting. Trim the rhizomes to 4-6 inch pieces and plant 12-18 inches apart, 2 inches deep in a prepared bed. Valerian grown from seed can be started indoors 6-8 weeks before the last frost date. Give the plants 14-18 hours under grow lights before hardening off and transplanting into the garden after all danger of frost. Direct sow seeds outdoors in fall or early spring, planting several seeds together every 12-18 inches and thinning later.
Keep plants well-watered, especially during hot, dry weather. Place a layer of mulch around plants to retain soil moisture and reduce weeds. Cut back any flower stalks to direct the plant’s energy into root and leaf growth rather than seed production. Valerian requires minimal fertilization, only needing an application of fish emulsion or compost tea a few times over the growing season. Stake or cage tall varieties that tend to flop over from top-heaviness. Monitor for aphids and thrips which can be dislodged with a strong spray of water. Valerian has few serious pest or disease problems.
Harvesting and Preparing
Valerian roots and rhizomes are harvested in late fall after the foliage dies back but before the ground freezes. Carefully dig up mature plants, removing soil then washing and drying the roots before use. The roots can be used fresh, or dried for later use in teas, tinctures, and supplements. Spread freshly harvested valerian roots on screens or mesh trays out of direct sunlight until thoroughly dried. Store dried valerian roots in airtight containers in a cool, dark place to preserve medicinal compounds. Properly grown and dried Valerian Standardized Extract produces potent therapeutic remedies to help fight insomnia, anxiety and pain.
Where Does Valerian Grow Naturally?
Valerian grows wild in many parts of Europe and Asia. It is native to the temperate climates and altitudes of southwest Asia and Europe, including England, southern Scandinavia, the Mediterranean region, Russia and the Caucasus. The plant favors damp conditions and is commonly found growing along streams, in flooded meadows and in partially shaded woodland areas. Valerian has been introduced to North America, Australia and other temperate regions where it has naturalized readily. The herb can be found growing wild in moist fields, thickets and roadside ditches, spreading readily where conditions suit its preference for rich, moist soil.
What Climate Does Valerian Grow In?
Valerian is best suited for growing in temperate climates with cool summers and cold winters. Ideal conditions for growth include daytime summer temperatures between 65-70°F and nighttime temperatures around 55°F. Valerian can withstand winter temperatures as low as -5°F provided the roots are protected by insulating snow cover or mulch. Hot summer temperatures above 85°F will inhibit growth and reduce medicinal potency. Valerian grows best with cool summer nights and brightly sunny but not excessively hot days. The herb thrives in areas with high humidity and consistent rainfall. Perfect areas to grow valerian include coastal and mountain regions where fog and cloudy skies help moderate summer heat.
What Zone Does Valerian Grow In?
Valerian grows well in USDA plant hardiness zones 3 through 9. Zone 3 covers areas with winter lows between -40°F and -30°F, while Zone 9 includes regions with winter lows of 20°F to 30°F. Valerian can survive cold winters with adequate snow cover insulating the roots and rhizomes. However, hot summer weather in Zones 8 and 9 may reduce growth. The herb flourishes in Zones 4-7 where summer heat is moderated by cooler nights, moist conditions, and partial shade. Zone 5 growing areas with winter lows from -20°F to -10°F provide close to ideal conditions for cultivating high-quality valerian root.
Does Valerian Like the Sun?
While valerian will tolerate partial shade or dappled sunlight conditions, full sun exposure results in the highest concentration of medicinal essential oils in the roots and rhizomes. Valerian plants grown in 8 hours or more of direct sunlight per day show markedly higher levels of therapeutic valerenic acids compared to plants in shadier locations. Morning sun in particular seems to boost chemical constituents. However, excessively hot afternoon sun can dry out the soil too quickly. Some afternoon shade allows the soil to retain adequate moisture on hot days. Proper sun exposure is critical for both successful valerian growth and optimal medicinal potency.
Does Valerian Grow in America?
Valerian was brought to North America in the 17th century and planted in colonial gardens for its medicinal benefits. Escaping cultivation, the herb quickly naturalized and could be found growing wild across the eastern half of what is now the United States by the early 1800s. In the U.S. today, valerian grows freely in moist fields, wetlands and roadsides from Maine to Florida and west to Oregon and California. High-quality valerian is commercially cultivated in Oregon, Idaho, California, and the Great Lakes region, prized for its medicinal properties. The transition zone from southern Canada through the northern U.S. provides excellent growing conditions for valerian. The Pacific Northwest also has ideal climate conditions to support thriving valerian plants.
From its origins in Europe and Asia, valerian has spread around the world and can readily grow in many regions with suitable climate and soil. While it propagates freely in the wild, cultivating valerian under controlled conditions ensures the highest levels of medicinal compounds for use in natural remedies. With attention given to proper sun exposure, moisture, soil fertility, and temperature extremes, valerian will reward growers with bountiful harvests of roots and rhizomes packed with beneficial phytochemicals. As demand for natural anxiety and sleep aids continues to rise, growing optimal medicinal valerian will become increasingly important. Both small-scale gardeners and herb farmers can succeed in producing robust, high-potency valerian crops when they understand and provide for the plant's ideal growing requirements.
