How to care for your Thyme
Everything you need to keep your Thyme healthy: watering, light, humidity, feeding, repotting and pruning.
Common thyme is a small woody subshrub native to the western Mediterranean basin, where it grows wild on dry, limestone hillsides. Its tiny evergreen leaves, grey-green and highly aromatic, concentrate essential oils with recognized antiseptic properties. In spring, it covers itself with small pink to lilac flowers that are highly attractive to bees. An exceptionally hardy plant, it can withstand cold down to -15°C and only requires well-drained soil and sunshine.
Watering your Thyme
Every 7 days
Water sparingly, allowing the substrate to dry out completely between waterings. Thyme is very drought-tolerant and susceptible to root rot caused by excess water.
How to know it needs water
- Substrate completely dry
- Plant appears slightly wilted
- Pot feels very light
How much light a Thyme needs
Full sun
Full sun, at least 6 hours of direct light per day. Essential for fully developing its aromas.
- Direct sun tolerated
- 6 to 12 h a day
- Orientations that suit it
- South-east, South, South-west, East, West
Humidity and misting
30–50 %
30–50% No misting necessary. Thyme is a garrigue plant that prefers dry air and good ventilation.
Feeding and fertiliser
Every 90 days
Fertilize very little, at most twice a year. Thyme develops a better aroma in poor soil. Excess fertilizer produces soft, weakly fragrant growth.
- Recommended feed
- Very dilute organic fertilizer or light compost. · 5-10-10
Repotting your Thyme
Every 24 months
Use a very well-draining substrate: compost mixed in equal parts with coarse sand or perlite. Prefer a terracotta pot to encourage evaporation.
- When
- Spring (March–April)

The tell-tale signs
- Plant becoming bare in the centre
- Roots completely colonising the pot
- Vigour decreasing despite good care
Pruning your Thyme
After flowering in late spring and lightly in autumn. Thyme regenerates better when pruned regularly. Cut back flowering stems by a third without touching the old woody wood. Thyme does not regenerate easily from old stems. Harvest whole sprigs by cutting the young shoots.
Through the year
Watering is not set once and for all: it follows the light and the growth. Allow 13 days between waterings in the depth of winter, against 6 in the growing season.
