How to Grow Creeping Thyme
Thymus serpyllum
Creeping thyme is a tough, mat-forming evergreen ground cover that hugs the ground at just 5-10 cm tall. It thrives in full sun and poor, sharply drained soil — perfect between paving, on dry walls, and as a fragrant lawn substitute for low-traffic areas. Masses of tiny pink-purple flowers smother the foliage in midsummer, attracting bees and butterflies. Once established it needs virtually no care — just a light shear after flowering to keep it tight. Drainage is critical; wet winter soil kills it faster than any frost.
Yearly Lifecycle
Care Essentials
Rarely needed. Thrives in poor, well-drained soil. Over-feeding produces leggy growth that loses its mat-forming habit.
Watch For
- Root rot in wet soil
- Generally pest-free
- Crown dieback in waterlogged winter conditions
Companions
Lavender, Sedum, Dianthus, Rosemary

☀️ Light
Full sun, 6+ hours daily
Full sun is essential. Creeping thyme needs at least 6 hours of direct sun daily to flower well and maintain a tight, dense mat. Part shade is tolerated but growth becomes leggy.
💧 Watering
Very drought-tolerant; avoid overwatering
Extremely drought-tolerant once established. Water only during extended dry spells in the first growing season. Overwatering causes root rot and is the most common mistake.
🌱 Fertilizing
None needed; lean soil is ideal
No feeding required. Creeping thyme thrives in poor, lean soil. Fertilising encourages loose, floppy growth that defeats its ground-cover purpose.
✂️ Pruning
Light shear after flowering; avoid old wood
Shear lightly after flowering finishes in late summer. This removes spent flower stems and encourages fresh dense foliage. Never cut into old bare woody growth.
Growing Tips
Plant for cracks and crevices
Creeping thyme excels between paving stones, in gravel, and over dry walls where few other plants thrive.
Walk on it
Unlike most herbs, creeping thyme tolerates light foot traffic and releases fragrance when stepped on.
Shear after bloom
A light trim after flowering keeps the mat dense and prevents bare woody centres from developing.
