Vegetative Growth
3-8 weeksPlant establishes creeping runners with increasing leaf density; new leaves continuously emerge from nodes
Maintain consistent moisture and humidity. Feed with dilute balanced fertilizer every 2-3 weeks. Ensure adequate light but not intense heat. Thin runners if becoming too dense.
Mature Growth & Production
Ongoing (weeks 6+)Plant forms dense mat of round leaves on creeping stems; begins producing small white or pale pink flowers on thin stalks
Begin regular harvesting of outer leaves to encourage bushiness. Continue consistent watering and humidity. Maintain moderate fertilization. Flowers are edible and can be harvested.

Harvest Tips
Begin harvesting outer leaves once plant is 4-6 weeks old and well-established. Pinch off leaves individually or cut stems with 3-4 leaves. Harvest frequently (2-3 times weekly) to encourage branching and prevent flowering. For maximum potency, harvest in morning after dew dries. Can be harvested continuously year-round in warm climates. Fresh leaves taste best; use within 1-2 days of harvest or dry for tea.
