Growing, Harvesting and Storage

Hypericum calycinum grows best in well-drained, loamy soil with a slightly acidic to neutral pH, preferring full sun to partial shade for optimal growth and flowering.

It requires moderate watering, allowing the soil to dry slightly between waterings to prevent root rot, and benefits from regular mulching to retain moisture and suppress weeds. For care, pruning spent flowers regularly encourages continuous blooming, and dividing the plant every few years can promote healthier growth and prevent overcrowding. The best time to harvest Hypericum calycinum is during late summer to early autumn when the flowers are fully open and the plant is at its most potent; harvesting should be done by cutting the flower heads just below the blooms with sharp, clean scissors.

To preserve its medicinal potency, the harvested material should be dried in a cool, dark, well-ventilated area, then stored in airtight containers away from light and moisture, or refrigerated for extended shelf life.
