Growing, Harvesting and Storage

Pelargonium graveolens grows best in well-drained soil with a pH between 6.

0 and 7. 0, requiring full sun to partial shade for optimal growth and essential oil production. It thrives in warm climates with moderate water supply, needing regular watering during dry periods but avoiding waterlogging to prevent root rot. Regular pruning and fertilization with a balanced fertilizer during the growing season help maintain plant health and enhance essential oil concentration. Harvesting should occur in the early morning when essential oil content is highest, using scissors to cut the leaves and flowers carefully to preserve their potency.

After harvesting, the plant parts should be dried in a cool, dark, well-ventilated area, then stored in airtight containers away from light and heat to maintain their medicinal properties.
