Expert tips
The key tip
Thymus herba-barona tolerates drought well but hates staying wet in winter. In humid climates, plant it in a raised bed or pot.
The common mistake
Don't mulch or add bark around the base: rainwater or dew accumulates and the plant rots in November.
The pro's trick
Harvest young stems year-round (especially May to August): this rejuvenates the plant and prevents it from becoming woody.
Care
Watering
Water moderately during the growing period, especially if the soil dries out. Once established, caraway thyme tolerates drought well thanks to its deep roots. Avoid excess moisture in winter, which promotes rot. Sparse watering is preferable to overwatering.
Light Exposure
Place your caraway thyme in full sun, with a minimum of 6 hours of direct light daily. The sunnier the exposure, the more vigorous and aromatic your plant will be. It tolerates hot and dry conditions without any problem.
Pruning and Cutting
Trim lightly after flowering to maintain a compact shape and prevent the center from becoming bare. Pinch young shoots to encourage branching. You can regularly harvest sprigs for cooking, which promotes density.
Fertilizer
Caraway thyme doesn't require significant nutritional inputs. A light application in spring is more than enough. Poor soil actually suits it better than rich soil, which can promote soft growth and less aromatic foliage.
Soil and Drainage
Drainage is essential: choose a well-aerated, light and permeable substrate. Add sand or gravel if your soil is too compact. This plant thrives in chalky soils and doesn't need frequent amendments.
Diseases and Pests
Caraway thyme is very hardy and rarely affected by diseases. Excess moisture is its main enemy, causing root rot. In very dry climates, watch out for spider mites. Good air circulation prevents most problems.
Did you know?
Caraway thyme owes its scientific name 'herba-barona' to a Corsican legend: the plant is said to have been born from the fragrance of a baroness who adored it, or was named in her honor. In Corsica, this wild thyme is a local icon, renowned for its delicate aroma reminiscent of caraway, and remains a traditional ingredient in Corsican aromatic herbs.
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.
