How to grow Common Thyme
Planting
Plant in spring in the sunniest, driest position you have. On clay, grow it in a raised bed, a gravel bed or a terracotta pot with plenty of grit in the compost. Winter wet at the roots kills far more thyme in Britain than cold does.
Pruning
Trim lightly after flowering, taking off the spent flower stems and a little of the current year's growth to keep the plant tight. Do not cut back into the bare woody base — thyme regrows poorly or not at all from old wood.
Propagation
Semi-ripe cuttings in early summer root readily. Low branches often self-layer and can be detached with roots. Seed is possible but slow and variable.
Pests and diseases
Little troubles it. Root rot from cold wet soil is the usual cause of death, and plants can suddenly collapse after a wet winter.
Value to wildlife
The small summer flowers are excellent for honeybees and solitary bees, and are worth leaving rather than shearing off early.
Notes
Thyme is short-lived and goes woody and sparse after about four or five years. Take cuttings routinely so you always have a young replacement ready rather than trying to rejuvenate an old plant.
