Establishment
2-3 weeksSmall rooted cuttings or seedlings with 2-4 leaves begin developing root systems
Keep soil consistently wet; maintain warm temperatures (70-80°F); provide bright indirect light; mist if indoors
Vegetative Growth
4-8 weeksPlant spreads horizontally with new stems and fleshy, spoon-shaped leaves emerging along runners; dense foliage develops
Maintain saturated soil conditions; fertilize every 2-3 weeks with diluted aquatic plant fertilizer; thin crowded growth if needed
Flowering
4-6 weeks (ongoing intermittently)Small delicate flowers (typically white or pale pink/purple) appear along stems above foliage
Ensure consistent moisture and warmth; flowering indicates plant vigor; maintain nutrient levels for seed production if desired
Harvesting
Ongoing throughout growing seasonStems are abundant with mature, full-sized leaves suitable for harvest and use
Harvest upper 2-4 inches of stems regularly to encourage bushier growth; use fresh or dry for teas and extracts
Winter Dormancy (cooler zones)
3-4 monthsGrowth slows significantly; foliage may decline in appearance
Move indoors or to heated greenhouse; reduce watering slightly but maintain moisture; lower light is acceptable; minimal fertilizer

Harvest Tips
Harvest upper 2-4 inches of stem tips when plant is established (8+ weeks old). Cut just above leaf nodes to encourage branching. Harvest regularly to promote bushier growth and prevent flowering (if foliage harvest is primary goal). Harvest in morning after dew dries for best potency. Fresh leaves can be used immediately in teas, tinctures, or eaten raw; dry leaves by hanging or using a dehydrator for storage. The entire aerial plant is harvestable.
