Thyme

Thyme

Thyme (Thymus vulgaris) is one of the oldest cultivated herbs and it was first grown in the Levant and surrounding regions. Thyme was used for a variety of culinary, religious, and medicinal purposes throughout the ancient and modern Middle East. It spread to Europe following Roman conquest, who used the herb to purify their rooms and add aroma to their food. It became popular in Medieval Europe as a symbol of bravery and courage, and was frequently given to knights as gifts before battle, another tradition likely brought about by the Romans [1].

Thyme grows best in hot, sunny locations with well-drained soil – all three of which are present in the Levant and other Middle Eastern regions. It grows as a perennial, and requires frequent pruning to keep from growing a woody stem [1]. Thyme is still grown across the Middle East today, although most of it comes from countries like Turkey, Spain, Jordan, and Morocco [3].

Growing Instructions for Thyme

FOR OUTDOOR GROWTH

LIFE CYCLE: Summer  and Orange thyme: Tender perennial in Zones 6–8. German Winter and Creeping thyme: Perennial in Zones 5–8.

CULTURE: Transplant (recommended) — Start seeds in flats 8–10 weeks before the last frost. Sow seeds on top of the growing medium and cover with a thin layer of soil mix. Keep moist until germination. Transplant to individual containers when plants have 4 true leaves. After last frost in spring, transplant outside and space 6–8” apart, in rows at least one foot apart. Pinch off growing tips off upright growing varieties to make bushier plants. Thyme will become woody and needs to be divided or replaced after 3–4 years.

Direct seeding is not recommended. 

GERMINATION: 14–21 days at 67–70°F (18–21°C).

LIGHT/SOIL REQUIREMENTS: Thyme does best full sun, except in very hot climates where it needs part shade to do well. Prefers light, dry, well-drained soil in full sun.

HEIGHT: 6–12”

HARVEST: Cut only a few leaves the first year in order for the plants to winter over. In subsequent years, harvest just as the flowers begin to open. Cut back to within 4–5” above ground.

 

FOR INDOOR GROWTH

Choose a container at least 6-10" deep with good drainage (clay pots with drainage holes are best). To germinate seeds, use well-draining potting soil and sprinkle seeds on top. Cover very lightly with soil. Keep soil moist until seeds germinate. To increase success, cover the top of the container with plastic to increase humidity until germination occurs. Once seeds sprout, continue to keep soil moist, but do not allow the soil to get waterlogged — Thyme grows better in slightly dry soil rather than wet soil. Place the container in a sunny location. Pinch stems back regularly to encourage bushier growth and prevent legginess. Trim flower buds as they appear, as this will encourage continued leaf growth and prevent the flavor from diminishing. Repot when overcrowding occurs.
