Growing, Harvesting and Storage

Ervatamia coronaria grows in well-drained, sandy or loamy soils in full sun to partial shade, preferring a slightly acidic to neutral pH.

It thrives in temperate climates with moderate rainfall and requires regular watering during dry periods, but it is drought-tolerant once established. To ensure healthy growth, it benefits from occasional fertilization with a balanced organic fertilizer and mulching to retain moisture and suppress weeds. Harvesting should occur in late summer to early autumn when the plant's essential oils are most concentrated, using clean shears to cut the stems just above the base to encourage regrowth.

After harvesting, the plant material should be dried in a cool, dark, well-ventilated area to preserve its potency, then stored in airtight containers away from light and moisture to maintain its medicinal properties.
