Thyme

Thymus vulgaris

Thyme (Thymus vulgaris) growing in a UK garden

Common thyme is a compact, woody evergreen subshrub producing intensely aromatic leaves used in stocks, stews, stuffings, and bouquet garni. Tiny lilac-pink flowers smother the plant from May to July, attracting large numbers of bees and butterflies. Native to the western Mediterranean, it is fully hardy in the UK and thrives in hot, dry conditions. Excellent for edging paths, filling gaps in paving, and planting in gravel gardens where the scent is released underfoot.

How to grow thyme

Plant in a sunny position with very well-drained, even poor soil. Thyme dislikes rich, moist conditions — lean soil produces the most aromatic leaves. A south-facing raised bed or gravel garden is ideal. Space plants 20-30 cm apart. Water only during prolonged drought. Do not feed or mulch. In containers, use a gritty, loam-based compost mixed with extra perlite for drainage. Harvest sprigs regularly throughout the growing season — this keeps plants compact and encourages fresh growth. Thyme is at its most flavourful just before flowering. Pick in the morning once the dew has dried for the strongest essential oil content. Plants become leggy and woody after three to four years, so take cuttings and replace them regularly.

Pruning

Cut back hard after flowering in late summer, removing about one third of the growth but never cutting into bare, woody stems. This prevents the plant from becoming leggy. Lightly trim in spring to tidy up any winter damage.
