About Creeping Lemon Thyme

Thymus citriodorus 'Aureus' · also called Golden Lemon Thyme, Creeping Lemon Thyme · herb

Thymus citriodorus 'Aureus' is a low, spreading lemon-scented thyme with tiny gold-variegated leaves that release a bright citrus aroma when brushed. Ideal for paths, cracks, edging and pots, it is drought-tolerant, bee-friendly and culinary. It needs full sun and sharp drainage, forming a fragrant, evergreen golden carpet.

Mature size: Low and spreading at about 10-20 cm tall and 30-40 cm wide, forming a dense carpet.

Watch for — Root rot from wet soil: The main cause of decline, from heavy or waterlogged ground. Plant in gritty, sharply drained soil, water only when the surface dries and avoid standing water, especially in winter.

How to tell creeping lemon thyme needs repotting

Repotting on a calendar is less reliable than reading the plant. For creeping lemon thyme, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot creeping lemon thyme

Every 2–3 years, into bone-dry mix. Creeping Lemon Thyme's growth habit — a low, spreading, mat-forming evergreen subshrub with tiny gold-variegated aromatic leaves; pale pink flowers attract bees in summer. — sets the pace.

What size pot to step creeping lemon thyme up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Creeping Lemon Thyme stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot creeping lemon thyme

Spring or summer, while creeping lemon thyme is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting creeping lemon thyme

Repot dry. Do not water creeping lemon thyme for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty gritty, sharply free-draining soil ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set creeping lemon thyme at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep creeping lemon thyme completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for creeping lemon thyme

Creeping Lemon Thyme wants gritty, sharply free-draining soil. Thrives in poor, stony, well-drained ground; amend heavy soil with grit or sand, or use a free-draining herb or alpine mix in pots. Neutral to slightly alkaline pH suits it. Waterlogging quickly rots the roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
