Valerian is a beautiful and fragrant plant that has been cultivated for centuries for its medicinal properties. It is believed to have soothing effects on the nervous system and is used to treat insomnia, anxiety, and pain. While it can be found in the wild, cultivating valerian in your garden can provide a steady supply of this medicinal herb. In this article, we’ll provide you with all the information you need to cultivate valerian in your own backyard.

Soil and Site
Valerian thrives in well-draining soil that is rich in organic matter. It prefers a soil pH of around 6.0 to 7.5. The site should receive at least six hours of direct sunlight, although valerian will tolerate some shade. It’s also important to choose a location where the plant can spread without crowding out other plants in your garden.

Propagation
Valerian can be propagated through seeds or root cuttings. If you’re starting from seed, sow them indoors six to eight weeks before the last frost. Sow the seeds ¼ inch deep and keep the soil moist. The seeds will germinate in two to four weeks.

If starting from root cuttings, you’ll need to wait until the plant enters dormancy in the fall. Dig up the roots and cut them into four to six-inch lengths. Plant the root cuttings horizontally in your garden bed in spring, 8-12 inches apart.

Watering
Valerian requires consistent moisture, but it doesn’t like to be waterlogged. Irrigation is usually only necessary during prolonged dry spells. Avoid overhead watering to prevent fungal diseases. Instead, water at the base of the plant.

Fertilizing
Valerian doesn’t require a lot of fertilizer, but it will benefit from a top dressing of compost or a slow-release organic fertilizer in the spring. Avoid using chemical fertilizers, as they can cause the plant to grow too quickly and diminish its medicinal properties.

Weeding
Weed control is important in valerian cultivation. Use mulch to suppress weeds and keep the soil moist. Hand pulling weeds is also an effective method of control. Valerian is a tall and bushy plant, so it should help shade out a lot of weeds on its own.

Harvesting
The roots of valerian are the most valuable part of the plant for medicinal use. The roots are harvested in the fall of the plant’s second or third year. Dig up the roots and clean them thoroughly. Cut them into small pieces and dry them in a well-ventilated area or use a dehydrator. Once they are dry, store them in an airtight container in a cool, dark place.

Pruning
Valerian doesn’t require much pruning, but you can deadhead spent blooms to encourage the plant to flower longer. In addition, you can cut back the plant in late summer to encourage a second flush of growth.

Pests and diseases
Valerian is relatively pest and disease-free. Slugs and snails can cause damage to the leaves, so use organic control methods to keep them at bay. Powdery mildew and root rot are potential diseases that can affect valerian. Adequate spacing, good air circulation, and proper watering can help prevent these problems.

In conclusion, cultivating valerian in your garden is a great way to ensure a steady supply of this medicinal herb. By following the tips we’ve outlined in this article regarding soil and site, propagation, watering, fertilizing, weeding, harvesting, pruning, and pest and disease control, you’ll be well on your way to cultivating a thriving valerian plant.
