Germination
10-14 daysTiny seeds begin sprouting; first miniature cotyledons appear within 10-14 days

Seedling
2-3 weeksFirst true leaves with characteristic rounded shape emerge; plant remains very small and delicate
Maintain high humidity with a humidity dome or frequent misting. Keep soil evenly moist. Provide bright indirect light. Thin seedlings gently to prevent crowding.
Vegetative Growth
4-6 weeksPlant develops creeping stems with dense tiny leaves; low-growing mat begins forming. Stem nodes root easily where they contact soil.
Water regularly to keep soil consistently moist. Provide partial shade in hot climates. Fertilize lightly with balanced fertilizer every 3-4 weeks. Pinch tips occasionally to encourage bushier growth.
Flowering
Variable, 2-4 weeks or longerSmall purple, pink, or white flowers appear on short stems above the foliage. Flowering may be sporadic depending on conditions.
Continue regular watering. Pinch off flowers if you want to encourage leaf production, or allow flowering for ornamental appeal and pollinator activity.
Established
Ongoing; several months to yearsPlant forms dense groundcover mat with vigorous creeping growth. Becomes perennial in appropriate zones.
Harvest leaves regularly to encourage bushier growth and prevent legginess. Divide or propagate from cuttings. Reduce watering slightly in winter. Cut back if plant becomes sparse.

Harvest Tips
Pinch or cut leaves from the top as needed once plant is established (at least 4-6 weeks old). Harvest in the morning after dew dries for strongest flavor. Can be harvested continuously throughout growing season. Cut stems above leaf nodes to encourage branching. Use fresh immediately or dry for tea. Freezing preserves flavor well for longer storage.
