Seedling
2-4 weeksTiny seedlings emerge with delicate cotyledons; growth is very slow initially
Keep soil barely moist, not wet. Provide bright light. Thin seedlings to proper spacing early.
Establishment
4-8 weeksSmall rosettes develop true leaves; plant begins creeping outward and forming dense mats
Reduce watering frequency; allow soil to dry between waterings. Avoid fertilizer as it promotes leggy growth in thyme.
Vegetative Growth
8-16 weeksDense mat of tiny, aromatic foliage expands; plant becomes increasingly groundcover-like
Minimal care needed. Water sparingly. Occasional light pruning encourages bushier growth and prevents sprawling.
Flowering
6-10 weeks, typically mid-summerDelicate pink, lavender, or light purple flowers bloom in loose spikes above the foliage
Do not over-fertilize or flowers will be sparse. Deadheading encourages more blooms; leave some flowers for pollinators.
Harvest & Maintenance
