Sow
Thyme can be brought at ready-grown plants, but is also easy to grow from seed.
In early spring fill small pots with seed sowing compost and scatter a few seeds lightly over the surface. Cover with a light layer of sieved compost and water gently. Place in a propagator to germinate. When seedlings are large enough to handle, prick out into individual pots.
Grow
Plants hate too much water and are fairly drought tolerant. Ensure plants in pots are not allowed to dry out completely for any length of time during long hot, dry spells.
Place a collar of horticultural grit or gravel around plants in the ground to protect the foliage from wet soil.
Clip to shape after flowering with secateurs.
Remove fallen leaves that settle on thyme plants in autumn to prevent rotting.
Protect plants in pots from excessive winter wet by placing in a rain shadow or a dry, light position and raise onto pot feet to allow the compost to drain freely.
Plant
Plant out in a warm, sunny spot in the garden. They demand well-drained soil and will rot over winter if the ground is too wet. If your soil is too heavy or you have a small garden, grow thyme in pots – they will thrive in 15cm (6in) pots filled with a gritty potting medium, ideally soil.
