How to Grow German Thyme

Soil, care & harvest

Prepare well-draining soil with a pH between 6.0 and 8.0, as this species tolerates a wide range but dislikes wet feet. Because thyme is a warm-season herb requiring frost-free conditions to establish properly, sow seeds outdoors only after the last frost date has passed. Alternatively, start indoors a few weeks prior if you wish to transplant later. Press seeds lightly into the soil surface and do not cover them deeply, as they require light for germination which takes 14 to 21 days.

Space plants 8 to 12 inches apart to ensure good air circulation throughout your herb garden. Once established, German Thyme is drought tolerant but benefits from low to moderate watering; allow the soil to dry slightly between waterings. Apply a light layer of mulch around the base in early summer to retain moisture and suppress weeds, though avoid piling it against the stems. Feed sparingly if growth seems sluggish, as this plant generally requires little fertilizer.

Watch for spider mites during hot weather by keeping foliage dry and ensuring good airflow; these pests are otherwise rare on this hardy herb. Avoid overwatering to prevent root rot, the primary disease threat. Harvest leaves once the plant reaches maturity, typically around 90 to 95 days after sowing. Snip stems just above a leaf node in the morning when essential oils are most concentrated for best flavor.
