What are the horticulural aspects of Thymus serpyllum?

Thymus serpyllum grow in well-draining soil with a pH between 6.0 and 8.0. It prefers full sun to partial shade and requires a minimum of 4-6 hours of direct sunlight per day. Creeping thyme is drought-tolerant but performs best with regular watering.

For optimal growth, plant creeping thyme in the spring or fall when temperatures are cooler. Space plants 6-12 inches apart, depending on the desired coverage. Water thoroughly after planting and keep the soil consistently moist during the first growing season. Fertilize lightly in the spring with a balanced, water-soluble fertilizer.

To harvest creeping thyme, snip off the top 1-2 inches of the stems using scissors or pinch off the flowers. Harvest individual leaves or stems as needed for culinary or medicinal use. Avoid taking too much foliage, as this can weaken the plant and reduce future growth. Harvest in the morning, when the oil content is highest.

Creeping thyme is susceptible to root rot, powdery mildew, and rust. Root rot is often caused by overwatering and can be prevented by improving drainage.
