Growing, Harvesting and Storage

Plectranthus barbatus grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires regular watering to maintain moist but not waterlogged conditions.

It thrives in warm climates and benefits from occasional fertilization during the growing season to promote vigorous growth. To ensure optimal health, prune regularly to encourage bushier growth and remove any dead or diseased foliage. Harvesting is most effective in the late summer to early fall when the leaves are fully developed and aromatic, using sharp scissors to cut the stems just above a node to preserve the plant's vitality.

For storage, dried leaves should be thoroughly air-dried and stored in airtight containers away from light and moisture, or refrigerated to preserve potency and extend shelf life.
