Information Sheet for Thyme

Common Name: Thyme

Scientific Name: Thymus vulgaris

Areas of the United States Found in Nature

Thyme is commonly grown in gardens and can naturalize in sunny, dry areas such as hillsides and rocky fields throughout the United States. It is a hardy herb that thrives in well-drained, sandy soils and full sun. It is often found in herb gardens, culinary gardens, and as ground cover.

How to Identify It

Thyme is a low-growing, woody perennial herb that forms dense, mat-like growth. It has small, aromatic leaves that are gray-green and oval-shaped, often with tiny hairs. The plant produces small clusters of pink, purple, or white flowers that bloom in late spring to early summer. Thyme has a strong, distinctive fragrance due to its high essential oil content.

How and When to Harvest for the Highest Medicinal Value

Harvest Thyme just before the plant flowers, as this is when the essential oils and medicinal compounds are at their peak. Snip the stems in the morning after the dew has dried, using scissors or pruning shears. Thyme can be harvested throughout the growing season by cutting back the top 5-6 inches of growth, leaving the woody stems to regrow.

How to Preserve the Herb for Future Use

Thyme can be used fresh or dried:

Drying

Bundle small bunches of Thyme and hang them upside down in a dark, cool, and well-ventilated area, or use a dehydrator on a low setting. Once dry, strip the leaves from the stems and store them in airtight containers away from light and moisture.

Freezing

Chop fresh Thyme leaves and place them in ice cube trays with water to freeze. Store the cubes in a sealed container in the freezer.

Medicinal Uses

Thyme is known for its antimicrobial, antiviral, and antioxidant properties. It is often used to treat respiratory issues, improve digestion, and boost the immune system. It is also used topically for skin conditions due to its antiseptic properties.

Tea

Steep 1-2 teaspoons of fresh or dried Thyme leaves in hot water for 10-15 minutes. Thyme tea can help relieve coughs, sore throats, and digestive issues.

Tincture

Fill a jar with fresh Thyme leaves and cover them with a high-proof alcohol like vodka. Seal the jar and let it sit in a cool, dark place for 4-6 weeks, shaking it occasionally. Strain the liquid into a clean bottle. The tincture can be used in small doses (usually 1-2 ml) to support the immune system and treat respiratory ailments.

Infused Oil

Infuse fresh Thyme leaves in a carrier oil like olive or coconut oil. This infused oil can be used topically to treat minor cuts, scrapes, and skin infections.

How to Propagate for Annual Use in Your Garden

Thyme can be propagated from seeds, cuttings, or by division.

From Seed

Sow Thyme seeds indoors in early spring or directly in the garden after the last frost. Scatter the seeds on the soil surface and press them lightly, as they need light to germinate. Keep the soil moist until germination, which typically occurs within 2-3 weeks.

By Cuttings

Take cuttings from healthy Thyme plants in late spring or early summer. Remove the lower leaves, dip the cut end in rooting hormone, and plant the cutting in a pot with well-drained soil. Keep the cuttings in a shaded area until they root, then transplant them into your garden.

By Division

Divide mature Thyme plants in the spring or fall. Dig up the plant and gently separate the roots into smaller sections, each with at least one stem. Replant the divisions at the same depth they were growing before, spacing them about 6-12 inches apart. Water well after planting.

How to Over-Winter the Plant

Thyme is hardy and can survive winter in most regions without special care.

Cut Back

After the first frost or once the plant has fully died back in late fall, trim the stems to about 2-3 inches above the ground. This helps prevent any disease and tidies up the garden.

Mulch

Apply a light layer of mulch, such as straw or shredded leaves, around the base of the plant after the ground begins to freeze. This helps insulate the roots and protect them from severe cold and temperature fluctuations.

Watering

Reduce watering during the winter months, as Thyme goes dormant and does not need as much water. Ensure the soil remains well-draining to prevent root rot.

In the spring, remove any mulch and allow new growth to emerge naturally. Thyme will regrow from its roots and continue to provide its aromatic leaves and medicinal benefits in your garden.
