What are the horticulural aspects of Phyllanthus amarus?

Phyllanthus amarus grow in tropical and subtropical regions, preferring well-drained soil and full sun to partial shade conditions. The plant thrives in areas with temperatures between 20-30°C and high humidity.

For optimal growth, plant phyllanthus in a location with good air circulation, about 30-40 cm apart. The soil should be rich in organic matter and have a pH between 5.5-7.0. Water the plant regularly, but ensure the soil is not waterlogged.

Harvest the phyllanthus leaves when the plant is about 30-60 cm tall. Cut the stems near the base, leaving about 5-10 cm of stem intact. Harvesting during the morning or late evening helps minimize damage to the leaves.
