Expert tips
The key tip
Thyme demands little but hates stagnant water. Plant it in well-drained soil, ideally poor soil, and water moderately in summer. Grow it on the dry side rather than wet—it's true Mediterranean nature.
The common mistake
Most gardeners kill thyme by over-composting and overwatering. Soil that's too rich makes it soft, unscented, and prone to rot.
The pro's trick
Cut it short after flowering (July/August) to keep it compact and bushy. This pruning stimulates aromatic new growth for winter.
Seasonal watch
In humid winters, check that water doesn't pool at the base. If you're in a very rainy climate, plant on a raised mound or in a pot to prevent root rot.
Care
Watering
Thyme dreads excess moisture. Water moderately when planting, then let it dry between waterings once established. In a dry climate, weekly watering is enough. Avoid wetting the foliage to prevent fungal diseases.
Exposure
Thyme requires a sunny location, minimum 6 to 8 hours per day. A well-lit spot promotes the concentration of essential oils and foliage density. Avoid partial shade or overly damp areas.
Soil
Prefer light, stony or sandy, well-drained soil. If your ground is heavy, improve it with sand or gravel. Thyme tolerates poor and even chalky soils. Soil that's too rich favors vigor at the expense of flavor.
Pruning
Prune lightly after flowering to maintain a compact shape and rejuvenate the plant. Regularly harvest stems for cooking, which stimulates branching. Avoid cutting into dead wood in late autumn.
Fertilizing
Thyme hardly needs it. A light application of compost in spring is more than enough. Excess fertilizer weakens flavor and hardiness. In pots, a moderate application once or twice per season is sufficient.
Diseases and pests
Thyme is very resistant. Watch for powdery mildew and rot if humidity is excessive. Good air circulation and regular watering are enough to prevent problems. Pests are rare on this plant.
Did you know?
Thyme inspired the ancient Greeks, who considered it a symbol of courage: warriors wore sprigs of thyme before battle. In the Middle Ages, it was placed under pillows to chase away nightmares and promote peaceful sleep. Its Latin name "Thymus" may come from the Greek "thymon," literally meaning "strength" or "energy."
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.
