Growing, Harvesting and Storage

Piper betle grows best in warm, humid climates with well-drained, loamy soil that is rich in organic matter and has a slightly acidic to neutral pH.

It requires full sun to partial shade and consistent moisture, especially during the growing season, though it should not be waterlogged. Regular weeding, pruning of old leaves, and occasional fertilization with a balanced NPK fertilizer will promote healthy growth and leaf production. Harvesting is best done in the early morning when the leaves are dewy, by carefully plucking the mature leaves from the stem without damaging the plant.

To preserve its potency, the leaves should be dried in a cool, shaded area with good airflow, then stored in airtight containers away from light and moisture, or kept in the refrigerator for longer shelf life.
