Expert tips
The key tip
Thymus serpyllum absolutely refuses heavy or wet soils. Plant it in very well-drained terrain, even rocky.
The common mistake
Watering it regularly: it's the opposite you need to do.
The pro's trick
After flowering (July), cut it short (2-3 cm).
Care
Exposure
Creeping thyme demands full sun to thrive. It tolerates shade and stagnant moisture poorly. Install it in a warm, very bright spot, preferably in a rock garden or on a slope.
Watering
Once established, creeping thyme requires virtually no watering. In a pot or as a young plant, water moderately after planting, then let the soil dry between waterings. Avoid excess moisture, which promotes root rot.
Soil
Well-drained, poor and chalky soil is ideal. Creeping thyme dreads compact, moist substrates. Enrich the soil with coarse sand or gravel if the soil is too rich in organic matter.
Pruning and cutting
Prune lightly after flowering to maintain a compact, dense shape. Leaves can be harvested fresh throughout the season. Regular pruning rejuvenates the plant and prevents it from becoming choked.
Fertilizer
No fertilizer is necessary, nor even desirable. Poor soil encourages better concentration of essential oils. Only a handful of very fine compost in spring is enough if the soil is very depleted.
Diseases and pests
Creeping thyme is remarkably resistant. Powdery mildew can appear with excessive moisture. Root rot threatens in damp soil. Prevention: good air circulation, impeccable drainage and no mulch that retains water.
Did you know?
Since antiquity, creeping thyme has been a symbol of courage and strength in Mediterranean culture. In the Middle Ages, warriors wore sprigs before battle. Its essential oils, rich in thymol, make it a renowned medicinal and culinary plant, capable of thriving on rocky slopes where few other plants survive.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
