Growing Thyme in Australia: The Complete Guide
Thyme is an easy perennial herb to grow, needing full sun with low, drought-tolerant once established watering.
We get asked about thyme often enough that it's worth setting out the full picture here, beyond what fits on our printable card.
Thrives on neglect
Thyme does best in lean, free-draining soil with minimal watering once established — rich soil and too much water actually weaken its flavour and vigour.
Planting Thyme
Method — plant from a nursery pot, or strike cuttings. Soil — free-draining, lean — avoid rich, heavily fed soil. Timing — plant in spring or autumn.
Ongoing Care
The key things to get right:
- Water sparingly once established.
- Trim after flowering to keep a compact, bushy shape.
- Avoid mulch touching the woody base.
- Divide or replace plants every few years as they get woody.
What Can Go Wrong
A few things matter most here:
- Root rot — from overwatering or poor drainage.
- Woody, sparse growth — from lack of trimming; prune regularly.
- Powdery mildew — poor airflow; space plants well.
- Few other issues — a hardy, low-maintenance herb.
When and How to Harvest
Signs — usable year-round once established. Method — snip sprigs as needed. Curing — air-dry hanging in small bunches. Storage — fresh in the fridge 1–2 weeks; dried, airtight for a year or more.
